ok i really need some helps, im running on aftermarket rims and tires right now, but i bought em as one of the first mods to my car, and i didnt know much about them and just got them for the looks, but now i read on how rims affect acceleration, lots of rotational inertia = bad, and generally smaller rim = less rotational inertia which allow the wheels to spin up faster, but then i heard on the other end that once the wheels do spin up their smaller circumference size means that larger rims cover more ground, is this true? The car is used mostly for point a to point b racing, no street and no oval track, what would be a good sized wheel? Also...is there any way we can get those nice Mickey Thompson drag slicks to fit on our cars? i know their not street legal and i heard slicks are bad for steering, but im just goin in a straight line, and how much time can drag slicks cut off 1/4's???

 

Yep bigger wheels will slow you down alright. I'd suggest slapping some 15" wheels on there and maybe some Nitto NT555R Drag Radials (street legal even ). As far as the giant rubber tires used in NHRA, it might be possible with a lot of work, I donno. If you do it lets see some pics!

All drag slicks are going to do is give you a ton of traction, and wear real quick. I've never experienced slicks before but I imagine after you lit them up you could launch at *HIGH* rpms.

Oh how do you like that JWT ECU? I've heard lots of people say that ECU upgrades don't do much.
