If the calipers are the same as on the 996 then in terms of calipers with adapters, you are struggling for the 6 pistons used on the 996 turbo and I think the 997.1 as the bolt spacing is similar to what you have, just a bit wider.

These are the two setups I have produced. One is a modified Cayenne turbo with bracket to take 997.1 350mm GT3 disks. The other is a 997.2 GT2 caliper with bracket for 380mm disks. Note the much wider bolt spacing on the later GT2 calipers. The rears can use a simple spacer.







I would run these with a 27mm master cylinder.

Hi MC
Are the bigger 997 calipers plug-and-play with the spacers onto a 996.2 C2? IF yes, would you be interested in producing some for sale? I’m sure a lot of people would be interested.

Yes they are, you can run the modified Cayenne ones on 18" wheels with 7mm spacers but the PCCB ones really need 19" wheels. I'll do a thread on them when I have the yellow ones on the car with wheels and tyres.

Hi Dagerous

I bought HiSpec 6-pots with 370x32mm rotors with Ferrodo DS2500 pads in the end. I say in the end because it seemed like I was waiting for most of this year for HiSpec to deliver........ They said they would deliver in 4 weeks but they took 10 weeks. I had to send the discs back because they didn't fit the hubs. After I got the discs back I then discovered the caliper mounting brackets didn't position the caliper central to the disc, so they had to make new brackets. All in all an absolute useless company. I wouldn't advise anybody to use them. I paid £2300 for months of false promises and agony.

I had read horror stories back in 2002 when I was building my Westfield kitcar but I thought 'it'll be fine, just a few bad stories on the internet'. How wrong was I. Their customer service is atrocious. I designed more of the brake kit than they did.

(Sorry for the rant, you did ask.... Smile )

Having said all that, I love the brake setup now. The car really hauls down and pedal feel is great. You can pin it to the apex with confidence. I wouldn't claim to know the in's and out's of other caliper manufacturers compared to HiSpec but I suspect any big disc setup (with appropriate size caliper pistons to master cylinder) with a decent pad would feel similar to what I have.

I also bought the GT2 plastic ducts. I'd be amazed if anybody could tell the difference between those and the standard Carrera ducts I removed but they were cheap and its cool to have a GT2 part on the car, haha.

If I was doing it again and I couldn't find a kit like what is being discussed above, after the heartache i had with HiSpec, I would quite happily pay £3340 for the Brembo GT 380mm kit.

Some pics to follow.

Hope this helps.

Craig
