volk gtp on the tt?
i'm looking into rims for my tt, and i'm thinking about volk gtp's. does anyone have any experience with these rims? are they forged like the [tl]e-37's? finally, any opinions on how they might look in 18" on a tt coupe? i'd like to do them staggered with ~18x8 (225/40/18) front and ~18x9.5 (255/35/18) rear.
all thoughts welcome.
regarding the wider rims: i don't understand -- are you suggesting that porsche twin turbos suffer from understeer? after all, they're all wheel drive and have staggered rim widths. as, such i have a tough time understanding your argument.
Offset it 30 up front and 20 at the rear,
Kumho 712 all round 225x40x18 and 255x35x18 rear.
Hope his helps,
Marcus

ps. one aspect of this equation that does make sense to me is sidewall flex -- for instance,
if one ran a staggered tire setup (e.g., 225/40 front 255/35 rear) on the same width wheel, i can imagine having problems due to the varience in sidewall flex (since the 255 is gonna be stretched in comparison to the 225). hence why i want to vary the rim width as well as the tire width.
As far as sidewall flex, i think the difference in height is neglible. As far as width.. its not that wider in back will cause catastrophic problems (understeer being safer), just that ideally i'd think you want to make the car as balanced as possible, which means not adding understeer. To me the TT is more like a WRC rally car (same size F&R) than a Porsche cup car with staggered wheel sizing.
As far as that rim on the tt.. IMO, it would look good in 9-10 in. widths with 255-275 tires and if the car was heavily modified.. to match the rims race looks.
