Fit the bigger RS rotors (to gain their superior heat dissipation) and retain the standard calipers spaced away from the hub to accomadate them.
A cheap alternative to Big Reds with most of the performance increase.
Great to do if you need new rotors anyway as RS ones are only marginally more expensive than standard ones.
I'm going to do this, but I use 17" (Cup) wheels for DE's and am aware that the caliper will foul the wheel without a wheel spacer. It should be fine if you run 18" wheels.</strong><hr></blockquote>
I run 7" and 9" X 17" Cup Wheels and Big Reds. I did not need to install any spacers. Big Red rotors are not cheap, neither are the pads, compared to stock pads. But who said that going fast was ever going to be cheap!

Hi,
I thought that big reds improved the 'fade' rate under repeated heavy breaking (ie on the track): and did not change braking distances etc.
What are the subject/objective opinions of those who have made the change?

I'm sure that's their advantage. I can't see how they'd make my braking distances shortes since I'm locking up (ABS want's to kick in) all the time with stock brakes.
BTW, now that I changed my pads to Hawk pads & took out all that anti-squeal stuff, pedal feel is much firmer.

Just read this thread. I think it's my car that MarkC is talking about (18"Ruf with RS discs, std calipers and modified caliper bracket). Dead cheap mod and it really does make a difference. The car does a lot of open pit track days (some like Spa and Bugatti are two day events). I have suffered from brake fad, pad break-up and fluid boiling over the last two years and have now found a setup that doesn't let me down. Here are some of the things I have tried with comments:-
ATE Super Blue Brake fluid - OK bit found Castrol SRF to be better. Costs a lot more but then...
EBC Green pads aren't up to serious track days. The red ones broke up at Spa and faded after a few laps.
Ferodo DS2000 pads worked well for about 6 sessions at Brands Hatch, then over heated, then scored the front discs beyond use. New discs and pads needed!!
Swapping to RS discs and std calipers was cheap and certainly gave me more brake. Helped the over heating problems I was having.
Porterfield pads are a different league. No fade and the pedal feels the same all weekend.
I had bespoke cooling made for me by Barwell Motorsports in the UK. 1 large scoop in the undertray at the front, a 'Y'splitter and two short 2.5" pipes direct the air onto the back of the caliper. Again it's cheap, doesn't give clearance problems and really works.
The current setup is RS discs, std calipers, Porterfield pads and SFR fluid. No issues with this - the car just stops every time you ask it to, no fade, no drama and the discs stay in good condition.
P.S. for info the car is a '94 993 Carrera 2, RS LWF and clutch, Bilstien PSS9s, RS top mounts all round, RS rear anti roll bar, RUF front roll bar. Milltek twin 100 cell cross over cats and rear boxes, AMD chip. 306bhp and loads of torque.

Yes Huffwood you are my inspiration for this, we spoke at Walton Hall and the Bedford PCGB Track Day....
FYI, I've had the PSS-9's fitted and set-up at AMD (by Nathan) and will be returning for the braking mods we're talking about here shortly.
How are the Portfield pads for road use? Very noisy?
I currently use EBC Green Stuff which are a reasonable road/track compromise but as you say they don't last long at the track.

They squeak when first fitted but after a few big stops they calm down. I just get a very quite squeak occasionally. They seem to be kind to the discs and wear fairly well although I did use 3/4 of the fronts at Bugatti (circa. 300 track miles).
