>Wow, that was really informative... thanx!

You're welcome. That's what I'm here for

Now when U say

>metal or something.

There are specific spacers made for putting on cars, but they should be easy to find. Just go to any local shop that sells rims for import/performance cars (there are about a million of these places now). Usually they are steel, but you might be able to find aluminum ones like I did (which are no big deal really). Either way they'll get the job done.

I also doubt you're causing any damage, it's just that stock lug nuts don't fit that well and might not be a good idea over the long term as they MIGHT loosen up as you drive.

Oh, I see you meant high end as high mph, as if your car can travel at a faster mph now due to the slight change in the final drive ratio. I don't know if it would really make that much a diffrence because with our gearing stock we could (if we had enough power) go about 162 mph or so (you'd be on the rev limiter in 5th gear at about 162mph). A taller tire would make it possible to travel at a higher mph, but we don't have to power to get even close to that (without a turbo kit) so the taller tire probably isn't affecting the top speed of the car, at least when it comes to gearing.

Now, the wider tires might actually slow the car's top speed down a few mph due to greater rolling resistance and more aerodynamic drag from just being a wider tire. (Yes, what may be small differences aerodynamically at low speeds become big differences as speed increases, because drag goes up with the square or the cube of your speed, I forget which.)

I meant high end as in power your car gets to the ground at high rpms (regardless of gears). For cars with relatively no power (that means us) turning 225 tires is alot harder than turning 195 tires. The heavier, wider tread will cause your car to be slower and put less power TO THE GROUND regardless of your rpms. That's what I meant when I said you are loosing high end as well.

Try getting that 1/8th or 1/4 inch spacer and see if that solves the problem.
