Independant Porsche GT3 MK1 Brake Specialist suggestions?

Hi,

I have a 1999 Porsche GT3 MK1 with the MK2 front brake upgrade with 350mm discs and the bigger calipers. I have had the car nearly 6 years now and the brakes have always been totally underwhelming / currently positively dangerous. It just simply doesn't stop and all that happens is that the ABS kicks in before any stopping happens!

I have had the discs skimmed, brake calipers overhauled, new braided steel hoses, new master cylinder, brake fluid changed. Tried some Pagid Pads, standard factory Pads and currently have fitted PFC 01 Pads. Tyres: Toyo Proxes R888 SG's Front / GG's Rear.

The car is used purely for the odd drive out to a 911uk meet or the occasional Sprint, so I'm not sure if I even need the bigger front brakes anyway which were on the car?

I recently took it to the Porsche Dealership in Tonbridge to have it checked out. They said that no ABS faults came up on the diagnostics, but that they could do no more as the car had been modified. All they suggested was that I try an Independent who would be willing to work on it.

The car is currently away in storage for the winter, so no immediate rush to get it sorted. If however someone can point me in the direction of a reputable/capable Independent Porsche/Brake Specialist who would be able to fix my problem once and for all I would be forever grateful.

I live in KENT but am quite willing to travel distances as required.

Thanks in advance......

N:B. I would also be interested too in having fitted a proportional brake bias valve into the brake system, to make balance adjustments as required.
 
You should speak with Matt @ Fearnsport. What he doesn't know about GT's isn't worth knowing. Pretty sure he would have come across this before.

Have you driven any other gt3's for reference?

Thanks for that, I was unaware of the company. Just had a look at on the internet and this does look like a good first port of call. Only 2 hours max. from me too!
 
While Fearnsport may be great and GT3 specialists they are a long way from Kent. Brakes are really not that complicated and I would expect any good dealer to be able to sort this out quickly. For example 9E or Precision Porsche are probably nearer to you.

How old are the tyres on the car?

I'm sure Nick could offer advice but Uber9s are a brake part supplier. They work closely with Fearnsport so would probably refer GP to them as already suggested.

Yes, I'm aware of that Terry. My angle was more from a troubleshooting/sleuthing perspective as Nick has tried and tested many different component combinations. Matt could check the hardware out without a doubt.

Good question. About 4 years now and marginally legal, I will invest in a set of new Pirelli road tyres before going any further, to eliminate these from the equation first.

Other questions: No I have never driven another GT3 or 996 to compare braking performance. Not related, but I also drive a BMW 535d and the brakes on this are superb. If the brakes on the GT3 were even close to this I would be fairly happy at the moment.

Thanks everyone for the advice on the various independent Porsche Specialists to try. All noted.
 
Don't worry about the tyres, they are only a factor if the wheels are locking up and your problem is the opposite. Indeed, in the dry, it's arguable that worn treads give better braking (Slicks!).

My std facelift car has a relatively heavy pedal feel. Not sure if that is typical because it's the only one I have driven but it certainly initially feels as though there is no braking compared with my Mondeo. However, press a little harder and they are excellent. After a few minutes driving, I get completely used to it.
