If I was smart im sure I could figure this out on my own but im not. Just wondering what type of effect in acceleration I would see going from 16 to 18s (I have 2.73 gears if that plays as big as a role as i think its going to). Also Im afraid I am getting 18s for the wrong reasons as in i hate how small my whels look now in comparison to the rest of the car. I like the wheels i have now but they just look so small and have so much rubber rapped around them and look tiny in the wheel wells. would I be better off buying 17s and springs to lower it an inch or so? Which would be best for performance?

I know thats a lot but I would really appreciate some help from someone that knows what they are talking about.

 

well for the best performance would be not lowering and not getting bigger rims.your gears are gonna kill you when you move up to a bigger rim cuz its got more to rotate.17" IMO is the best size for performance/street.
i wouldnt go with more than a 1.5" drop

 

it all depends on what you plan on doing to your car in the future. My car will never be an all out track car. I want an all around fun street car. So it didnt bother me much to get the 18s. I didnt notice much of a difference in power loss or anything, but then again i had 17s on there so it wasnt a big jump as you. Plus i have 4.11s. I like the way my 18s fit with my bmr springs(one inch drop) and my front lowered just a bit more cause i got the qa1's. Check out my link to see pics.
