PostPosted: Sat Nov 24, 2018 11:14 pm    Post subject: Bigger brake discs Reply with quote

I've been googling and can't find an answer to my question.
Can I get bigger brake discs for my 1998 996 c2 3.4. It's quite popular with different marques to go for larger brake discs and keep the same calipers by fitting a spacer in between the calipers and mounting point so the calipers sits further out from the centre of the hub. I see it can be done on turbo/c4s' from 330mm to 350mm.
At this point I should mention that I don't need these but it's the sort of thing I like. It's more a visual thing than anything else and might never do it. I could make the brackets if I could find the discs to suit.

Thanks vlad. Funny a cayenne set up was what I had looked at for my last impreza. I wasn’t really thinking of that but if there was a bigger disc available with a friction height to suit the pad pad area on the standard caliper, it’s only a matter of a spacer for the caliper.

If you do the fronts then you really should do the rears to keep the balance the same. GT3 front hubs and 6 piston calipers or Cayenne calipers with spacers would be the main options to keep them OEM. This is exctly what I have done, using 350mm 997 GT3 disks front and rear.

Yes, that's true.

I did a Cayenne Turbo brake upgrade on my old B5 RS4 and if you braked hard with any sort of steering angle on, you could definitely feel the imbalance trying to spin the car Surprised

I might never go this way with the brakes but it’s something I have done in the past. It’s just something to give the car more of a gt3 finish. I’d say I’ll probably never get gt3 brakes as I have a lot of other ways for the money to go, like suspension. My brakes are new all round before I bought the car so I don’t need it.
It’s just big brakes are the sort of thing that floats my boat

Rdodger that’s exactly what I was looking for. The photo of my Impreza brakes have rotors from reyland I’m told. I bought that kit 2nd hand off a rally car which came with the 8 pot calipers, brackets, the bells with 330mn rotors and brand new ferrodo ds2500 pads. The guy told me he sourced the rotors from reyland. It was an excellent set up. It wasn’t brembo/ap etc quality but they were sensational and saved my bacon on a few occasions as it was a very sharp car.
I did a lot of research on fitting porsche brembos to the rear on the p1 but never got round to it.
I have a background in cars but currently work in a small engineering shop so making brackets wouldn’t be a problem. It’s only a matter of sorting the discs to match the calipers and more importantly the pad size. There’s absolutely no reason why it has to be so expensive

You don't need bigger brakes for the road Ned, only on track maybe.

Good quality fresh discs, pads and fluid along with GT3 ducts should be fine on the road. Thumb

I agree. But they do look good. Ducts are super cheap from OPC.

I know I don’t need to need them. It’s more a visual thing. And it’s just the sort of thing that tickles my balls Very Happy

I will look into the ducts though. I’m just the type that likes to think what if.
I’m more than capable of doing/modifying anything to suit my needs. And I just like to have or make something that no one else has. Some of you guys have excellent threads on rebuilding suspension and that’s just the sort of thing I love. I enjoy working at the cars as much as driving them. If I’m fit.
I appreciate all the pointers I get on here. I’m only a new member but I think I’ll fit in very well Cool

Oh and while it’s in my head, anyone ever make a rear strut brace?

No point - the struts don't determine the rear suspension geometry, it's the upper and lower arms that do, and they're bolted to the subframe halves, which is bolted to the side members of the car.

If you want to 'stiffen' up the rear, replace the subframe rubbers with solid bushes - elephant racing do them.

Just got out for a run with my 8,4 and 3 year olds. What I can say is I’m very happy with the air box mod and I think the suspension feels very tight so unless I see anything when I get through it, I won’t be touching it any time soon. Obviously I wasn’t goin to fast withthe kids on board. It was their first time in in and they loved it which means I’ll be able to use it more often. Result
Never got a chance to get a feel for the brakes but again, they’re new before I bought the car. I definitely think a fluid flush and a fill of 5.1s definitely in order and maybe a set of braided hoses for good measure. Still be very keen on bigger discs if I can get them at reasonable money. On the front at least

Yep no denying big discs and calipers look great. I had the mk2 6 pots and Alcon discs on my GT3 and they filled the wheels very well.

If the car isn't going on a track though then it's just bling really and extra weight where you don't want it - unsprung and on your steered wheels. More negatives than positives from a driving aspect.

Alex. Just a little more noise but thought it was ok when just cruising. I have a full exhaust set on but think I can still hear the air box on full throttle

Mark. I know what you mean. It’s just the sort of thing I like doing. I know I’ll never need it.

On first couple of short runs when I got the car with tyre pressures around 32 before I looked at what they should be. Today I tried it with 36 front and 40 rear. Felt a lot better. Steering felt nice and sharp but very light at low speeds like parking.
Overall I’m very happy with it
