Rims size, change in performance Options

[gnetik]

hey guys, I was just wondering, how much difference would you feel between using stock 15 inch rims and 17 inch rims (not chrome or lightweight performance) such as the adr gt sports? Anybody who switched from stocks to 17 inchers, please tell me what difference you felt (how much slower). Also, anybody with track experience, what is the difference in quarter mile from stock 15 inchers and 17 inchers? Anybody with input please........uh.. input? haha! yeah, well thanks! (sorry if this is stupid question)

I don't know where you guys are getting your stock wheel weights from... but stock 15in alloys probably doesn't weigh more than 18 pounds a piece... and that's the very max.  I'd bet they're only about 15-16 pounds. 

Basically... if you're getting wheels over 17 inches... they're not gonna be performance lightweight wheels unless you're paying over 2g's for them... the cheapest may be some kosei k1s which can still weight as much as 17-18 pounds in 17 inches.  If you want lightweight wheels... 7th gen GTS wheels are nice and light... that, or get some 5x114.3 camry hubs pressed onto your spindles and buy some Rotas.

What would be the point of going to 5x114.3? They make Rotas in 5x100 in 40 and 48mm offsets.
