Well I finally got around to finishing my colour coded rear grill project.

A reminder of my previous journal entry....

jonttt wrote:
One of the few things left on my "to-do" list for this year......... has turned out to be a thing of beauty Very Happy ....

Colour coded rear spoiler grill


I had been tempted by the 2S split grills which are designed to be painted and are available as an OEM option for all 993.

However I did not feel that the split grill actually complimented the shape of the 993's sweeping rear and it was in fact the colour coding that made them appealing to me.

I decided that the ideal option for me was to retain the wide one piece grill which helps to emphasise the wide rear of the 993 widebody 4S but colour coded and not the contrasting OEM black on a silver bodied car.

This is not without its problems (and maybe part of the reason why you don't see many colour coded one piece grills) due to the fact that these one piece grills where never designed for painting.

I approached a few bodyshops which were reluctant to carry out the work and the general opinion was that normal painting would not work and that the grill would have to be primed using specialist plastic paint. Even then it would require addiitonal layers of paint and laquer to cover the textured finish and which would make it both costly and without their standard paint warranties.

I therefore decided it would be a good DIY project Surprised

The first stage was to source a second grill as I wanted to retain the original under my remit of any changes to the car being reversible. Once again eBay was my friend and a second hand piece was purchased.






Luckily for me one of the oldest and biggest car paint suppliers is based 15 minutes from my office and on advice from them I used a plasticoat paint as an initial primer to prepare the surface for more traditional primer to be used....




This was applied in very thin layers until a good but thin surface covering was achieved...... part way through the process.....




Once that stage was completed more traditional primer, paint, laquer process was followed but instead of the normal 3-4 thin layers being applied at least double that was completed for each layer over a number of days to allow plenty of time for curing.....

pre laquer....




I completed the paint earlier this week and spent 1.5 hours today polishing, waxing and sealing the paint.

I am really pleased with the end result which is much better than I could have hoped for......










So the final stage will be to fit it and then time will tell if the paint will hold (it does feel and smell gorgeous though lol)



I could have tried to fit the grill without removing the rear spoiler but seeing as I also needed to replace the spoiler curtain wall which has split I thought it sensible to tackle both jobs properly and remove the spoiler. (nb the spoiler curtain can also be replaced without removing the spoiler but its easier to see what you are doing with it removed, especially if you have not done one before).

So the starting point, standard 993 retractable spoiler with split curtain wall.......












The spoiler is simply held in place by x4 torx bolts......




These are easy to remove with either a ratchet or screwdriver with the correct size hex bit....

nb I dropped the spoiler to the 2/3 open position to make curtain fitment easier later. It does not affect access to the spoiler bolts.




nb you don't have to worry about nuts falling in the engine etc... as all of the parts except the bolt and its washer are fixed to the spoiler.

The 4 removed bolts...




As my spoiler curtain had completely split into 2 parts the spoiler just lifted away with the bolts removed but usually the curtain would still be fixed.

He is the car spoilerless but with the bottom part of the curtain still in place.....




To remove the bottom part of the curtain you simply need to pull it away from the retaining bar (nb this does take some force to get started)....






Once free of the retaining bar there is a rubber strip along the bottom which the curtain needs to be slid out of from the side. You can pull the rubber strip away from the car at this point and remove the curtain from it away from the car.

Here is the rubber strip removed from both the car and damaged curtain. This can be cleaned and reused....




A wipe over and treatment to keep it nice and flexible...




The rubber can then be refitted to the car....




and the new spoiler curtain slid into place along the top of the rubber.......




The curtain wall can then be attached to the retaining bar. Note that there is a plastic ledge about halfway up the curtain which retains a "dowl" that purtrudes from the car on both sides. Make sure these are placed on the ledge correctly prior to pushing the curtain onto the retaining bar....






and the new curtain wall fixed in place to the car....




Now onto the removed spoiler. The first job is to remove the top have of the old spoiler wall. This is very easy to remove and just slides off...




Normally you would refit the spoiler at this point affixing the top of the curtain as you go but I am replacing the grill for the colour coded one I prepped previously.......

The grill is held on by a combination of x10 "spring" clips and a bonding compound.

The first job is to remove the spring clips. These work by simply pushing onto plastic pins protruding from the grill through holes in the spoiler frame. They are sprung so that once pushed onto the pin they grip it and will not move away. To remove them it is simply a matter of removing the spring load on the pin using a small screwdriver blade....




Once all 10 spring clips are removed it should still be retained in place by the sealing compound. I was therefore expecting to have to slowly break the bond using trim tools. However after 16 years the compound had totally failed Surprised . This was great for me as the grill just fell away but not so good if you were not doing this job and your spring clips have rusted away Judge








Fortunately despite the compound still being available from Porsche I had already decided that 16 years was a long time in bonding compound science and had already sourced a newer product used for this purpose. I would definitely not use the Porsche compound if you are doing this job having seen it will totally fail over time.




It was pretty easy to remove the remaining bond on the spoiler frame and clean it all up. Nb this does not need to be removed 100% so long as the area is flat and even.




It was simply a matter of then running a bead of sealant, fitting the grill and replacing the spring clips onto grill posts at the back of the spoiler. The spring clips work really well and retain the grill in place with pressure to ensure a good bond....




And finally refitting to the car is the reverse of removal. I fitted the spoiler loosely at first using only the front most retaining bolt on each side. This allows the spolier to be moved forward / back and because it is in the 2/3 open position there is enough slack in the spoiler curtain to easily push it into place on the spoiler. Once the spoiler curtain is in place the remaining bolts can be lined up and everything tightened up. Job done !

A new spoiler wall in place.....




and the fitted colour coded engine grill........








I am really pleased with the final result. It is just what I was looking for.

Here is a before and after for comparison......

Now I am always up for a bargain and part of my hobby is sourcing parts as cheaply as I can. However there are occasions when impulse gets the better of me and "Man Logic" is just not logical at all.

Last week Man Logic failed me completely PC

One of my current "holy grail's" had been an original 993 Tequipment Carbon Handbrake lever to match my gear stick. These were expensive new 16 years ago (c£600) and so are pretty rare so far as I can tell. I've certainly seen very few 993's with them fitted.

To make the search even harder I was only interested in a true RHD version (ie with the Porsche lettering facing the driver).

I had enquired with Porsche and although the item is not NLA (No longer available) there is no stock at all and so they are made to order. The problem is Porsche will not arrange for them individually and so you have to wait for a batch of orders to be met. Although "batch" was not quantified to me in terms of how many that was I was told I could wait for over 12 months Sad

So I resigned myself to the holy grail in the hope that sometime over the next few years a second hand RHD one would come up for sale......

So imagine my surprise when a NOS (brand new old stock) original 993 part number, black in RHD Tequipment carbon hand brake came up for 99p auction on ebay from a seller in Holland Bandit

My holy grail to the max......

It was a long 9 day auction frustrated

The same seller also had a NOS full carbon dash trim kit for sale which ended 20 minutes before the handbrake. Now I was obviously also interested in that (for a reasonable price) but the priority was the handbrake as I'm not 100% about the dash kit.

So I spend a week deciding how much to bid and biding my time.

I decided to bid slightly over what I figured most people would offer for the trim kit as I figured if I ended up not fitting it I could always sell such a rare kit on and get my money back.

The trim kit went for a fortune Surprised

Now this panicked me as I figured anyone willing to pay really strong money for the trim kit would probably want the matching hand brake lever Sad

To make matter worse during this 10 minutes I was in the middle of a poker tournament and so only had my phone with me PC

So in between poker hands Mann Logic came into force. I figured if I lost the auction I could always order one from Porsche. However, could I wait 12 month, would it take years. Could I convince my fellow 993ers that a group buy for a carbon handbrake at £600 was a wise thing to do Question Would Porsche make them NLA Surprised

So I did the only sensible Mann Logic thing to do. I put a stupid last minute bid into ebay at well over RRP Very Happy

I won the auction by 50p Grin

I had a mixture of elation and then a feeling of "how can you spend so much on a hand brake!"

I exited the poker tournament with aces being cracked by 46 off within 5 minutes of the auction end PC

So I've been slightly in a state of Man Logic shock this week but the handbrake was delivered in quick time by the seller.

The great news is that the item is exactly as described NOS and even had the original box and labeling in place.

A brand new unused original 993 Tequipment black leather / Carbon handbrake in RHD ...........








and fitted....










Needless to say I paid significantly more than £600 for it but I am really chuffed to bits iwith it and sometimes you just have to dig deep for that holy grail Bandit

You're mental. I was watching that an know what it went for Surprised

I wasn't actually interested in it for mine as I prefer the leather and alloy version personally. I think they can still be purchased along with gear lever but the price is eye watering. My excuse for not buying is retention of originally Grin

You have got to treat yourself now and again lol

I class any porsche part which was available to fit to the car when new as being original. Different definitions I guess Wink

£1,100 quid for new Tequipment alloy/leather handbrake lever and gear knob nooo

The standard black leather ones in my C4S are pretty smart. Certainly like them more than the steel grey painted ones I had in my old S. Was never a fan of those.

Wow, your spending is making my tight-fistedness look really bad. I'm having an internal debate over whether I can justify an exhaust upgrade on top of the maintenance (check-strap broke again...).

Joking aside, I like the job you've done on the spoiler. thumbsup

Wish I had the confidence and skill to do something similar but judging by the dogs-dinner I made of my garage door I won't be tackling any paint jobs on the porsche in a hurry.

Rob if there was one upgrade I would do first it would be the rsr muffler conversion. You really need to bring out that oil cooled burble. I believe the hollamby bypass is similar for less cost.

I would definitely recommend it, I love the look. Looks very very OEM as if porsche should have done it that way in the first place.
It's also a surprisingly easy install and therefore reversion back to OEM if needed.

It cost me £60 for the second hand grill (I'm not sure how much a new one is?) and c£40 for paint and sealant so for £100 it is Big Bang for the bucks IMHO.

If you doing it in winter don't do it with the temp too low as it makes it harder to get a good finish and for the paint to cure.

Use a plastic primer to pre prime and then prime, paint and lacquer as normal. I just took my time over a few days and built up extra layers than normal due to the plastic texture.

I would also get the paint cans from one of the online suppliers. Just give them your paint code. You get a lot more paint in a can than normal and they are cheaper. I'm lucky enough that one is based near my office so I just nip round.

thanks for the tips Jon. Will look out for a second hand one on the bay and try to get it done before the weather turns. I'm ok for paint thanks as I had the whole car repainted last year. At the time they provided a swatch of the exact shade on a sample plate. Got a large can mixed up at a local paint shop.

Will post some photos when I get it done. Can't promise them to the detail of yours tho Smile

lol unfortunately I've been busy at work and outside but the 993 has had a new stablemate to compensate Bandit




this dial always makes me smile




unbelievably I'm getting the same MPG as the 993 Grin

I have not neglected the 993 totally though......... I have a new replacement part for the faulty vacuum system to be fitted when I get 20 minutes and I picked up one of these Dont know






Its an original Bosch Porsche specific 301 "Hammer" diagnostic tool Smile

I've not really had chance to play around with it yet in detail but it does seem a fantastic piece of kit. I can switch individual servos, etc... on / off and so I know for example that the oil cooler high / low fan ballast controller is working properly as I have full control over turning it on/off at the press of a button.

It has come up with two faults which I think are related to the part of the vacuum system I currently have disconnected due to the faulty diaphram to be replaced.....



Hopefully I'll get chance over winter to have a full play around with it and I'll post up a full review.

Obviously I'm available for diagnostic checks at car shows next year for a cup of coffee Wink
