I have one in PDF format but not an actual, physical copy, and my dealer asked me not to post it anywhere but you may be able to obtain one from your dealer.
Plus the WP is really just cosmetics at this point, no real proven weight reduction and performance benefits. The mag wheels yes, but I like the design of the standard and can get a set of track wheels to abuse for way less money and have similar weight reduction.
Do you or does anyone know of wheels that would work on the GT4RS, same dimensions, ET, width, 20 inch dia that are approaching the weight of the factory option magnesium wheels? I have been trying to find something that will work but have been unsuccessful so far.
I was able to save 16 pounds of weight on my Cayman R which came standard with the lighest 19 inch wheels Porsche had up to that point in time, the Spyder wheels. Due to the Cayman R relatively small standard rotors I went with OZ Racing HLT wheels in 18 inch dia, with the same width as the 19 inch Spyder wheels. I put the Spyder wheels away to keep them nice for the next owner, (which may be coming up when I get my GT4RS in January).
But the GT4RS has such large brakes whether iron rotors or PCCB. The calipers do not have much clearance to the wheel barrel. I do not think downsizing to 19 inch dia will work, plus they must be centerlocks.
If anyone knows of lighter weight wheels (than the standard GT4RS aluminum forged wheels) please share your info.

HRE R101LW's or BBS FI-R's are both about 16 pounds front and 19 pounds rear for 20's on the GT4/Spyders. Both are probably working on coming out with a set for the 4RS.

The most recent BBS are now called FI-R Evo and should be coming in 4RS sizes…

Litespeed Magnesium.....you could do 19" if you also swap the brakes for AP or PFC system.
For the ones who already took delivery or broken in, has anyone installed the DSC module as replacement to the PASM? Does that make the same impact as the regular GT4 or is the "out of the box" suspension tuning of the 4RS already on the sweet spot? What about alignment?
Thanks!
Bumping this question from @tdlondon . I didn't see any replies. Has anyone tried the DSC Controller with a GT4 RS? @TPC Racing - any experience with the GT4 RS's yet?
I am amazed at how sublime the ride is on bumpy country roads in my GT4 with the TPC Rear Toe Links and the DSC Controller. I swear it is less harsh than my GTS 4.0's (with the stock suspension and the DSC). Sublime in ride quality and fantastic control at high speeds over sketchy terrain.
