Hey everyone. I was wondering if 18's will really hurt the XB's performance (not handling, but acceleration performance). There will be a decent amount more rotational mass, and a bigger diameter. Is it going to make what is a slow car even slower? Thanks!

most likely the 18 will be about the same diameter as the stock 15s as long as u dont get alot of crome u should be ok it should not make as big as a differents as u would think but if the diameter is big then stock your speed will be off a little i think thats going to be your bigges problem

Actually they will be bigger because I'm running 17" w/ 205/40/17's and they are about they are mere millimeters larger then the stocks so the 18's with 35 series would be larger. Just try to steer away from heavy 18's and you should be good.

I have 18x7.5" ADR Sokudo 8s, which weigh 26.5 lbs w/o tires, and there is no noticable decline in power.
