Title: R32/S3 rear floating discs
Post by: Daemon on July 03, 2011, 04:23:55 pm

Hi guys,

I've just done the R32/S3 rear brake upgrade so I weighted the discs, the result was about 16kg a piece wich is kind of heavy.Is there any possibility to get floating discs? does anybody make some? I guess you can shave about 5-10Kg wich is a lot for us time attack guys.Less is more right ?:)

DaveB a little help please


Cheers,
Alex

It's impossible for the rear 310mm discs to weigh that much. The fronts are about 11Kgs/piece. Rears should be like 7kg/piece !

What about RS4 rear discs?

Or RS6 rear discs.....at the behest of the 450-500bhp TTRS chaps, just done these you need around £1k and alloy rear hubs but works and fits well.

Are they C6 discs Dave?

2003-2005 so C5 I think.

It's win win, the TTRS chaps are uber weight sensitive, even with the adaption there's no weight increase, the disc are directional and sort of floating.

Even though it's a heavy casting, the OEM 310mm disc won't take much heat so you're sort of limited to a DS2500 pad really, the better disc allows RS29's in essence the next group of pads up.

The TTRS caliper carriers are required they're different to R32/S3 ones
