How much slower am i going to be with 16"

[DaksGT]

It's probably a dum question, but I bought OEM GT-S wheels with the Yoko's, so I was wondering how much if at all will this slow me down.

heh... i'll let you know...

i've been running autox w/my 18" rh d6000's w/215/35/18 paradas...

just got my stolen stock 16's back w/kumho's on them, and there's an event on sunday.... i'll let you know how i did

you're gonna have about 27% more rotational inertia in the wheels cuase of both the outstreched center of gravity and the increase in wheel and tire mass...

good thing: lower profile, more metal on the road.

Smaller diameter tire= faster turn in, slightly lower gear ratio, lower center of gravity/roll.
If you are a TOP AXer, it would make a few tenths difference on a 60 sec course. For most of us mere mortals, driver skill and tire grip will make a much bigger difference.

SO basically I wont notice it?
:D

[pitcrew]

EXACTLY!

yep... i didn't notice much difference when running w/my stock 16's yesterday compared to the 18's.

I did notice that the car was a little springier around turns, but that was most likely due to the sidewall flex (50 series compared to 35 series)
but yeah... i placed in the general area that i usually place in...
