I have 20" Lexani rims (deep lip in rear), and needless to say, they're considerably heavier than the stock. My question is: how much of a difference will it make in my 1/8 and 1/4 mile times? I know that it's hard to tell unless you know exactly how heavy they are, but is it going to be around .1-.2 sec in the 1/8, less, more?

Any imput will be appreciated

 

Heavy wheels will make a huge difference. Even going from my heavy winter wheels which are Blizzaks on 17" base 350Z wheels to the summer tires on the OEM RAYs 19s is VERY noticeable, even on the street. I use a lot less throttle to get rolling and the throttle response is much snappier on the forged 19's.

 

i like the look of bigger rims
