OEM Porsche vs Sachs Lightweight Flywheel/Clutch Kit
Is there a difference between piecing together a lightweight flywheel/clutch kit using OEM Porsche RS parts and the Sachs Lightweight Flywheel/Clutch Kit? Would always prefer OEM but the difference in price is substantial. When do you guys suggest? Are the parts the same just without porsche branding?

Yes, Sachs is def the supplier of the Porsche parts. I found an old post stating that the Porsche clutch disc was measuring thicker then the Sachs equivalent...like Porsche made some modifications that were unique to their own part. This seems unlikely though.

The Sachs RS clutch kit that most aftermarket Porsche suppliers/Rennlist sponsors sell that is "compatible" with the 993 uses the stock 964 pressure plate (blue dot). If you buy the pieces separately from Sachs you can buy the 993 pressure plate which has a greater clamping strength and as such will last longer. You have to download both Sachs catalogs to figure this out... I couldn't say whether or not the OE and OEM discs are still a different thickness, they were 10+ years ago. Somebody recently measured an OEM disc and posted but they didn't take into account that there are springs between the two discs which make it appear thicker. Nowadays the price spread between OE and OEM is just too large to ignore. The only thing I would be careful about is that Sachs (boxed as LUK and a few other companies, etc.) pressure plates from Rockauto have been turned on a lathe. Which would point to a remanufactured plate (and all the flange corrosion makes you wonder too) even though they are shipping with the regular part numbers and not the R number.

This!!!!^^^^^^^
I went with the "764" PP, and 997GT34.0 disc, both "Sachs" motorsports parts.
