17's or 15's

I have some 17" rims that weigh 13 pounds each and i was wondering if i should use my 17" 13 lbs. rims or my 15" stock rims when i race.

with smaller diameter wheels will spin up faster than larger diameter. but 1 lb of wheel weight is equal to 8-10 lbs of static car weight so if you're 15s are really heavy then i'd go for the 17s. im not sure though, wait till CivicSiRacer or jackasssi responds, they knows a bunch about suspension.

what size tires are on the 15s? 195/50 15?

what type of racing?
what size tires?

Seriously man :biggrin: Rota slipstreams in 15''s weigh almost 13 lbs

my friend has some 17s that weigh 11 lbs each... they're a new company and i dont remember the name. they were 1600 for the set though.

SSR Competition are that light. But that's about the only one I can think it can be?

I was thinking maybe TE37's.. but at 17x7 im pretty sure they weigh around 15 lbs
