Agreed on that one. To try and compensate...either turbo or get an upgraded clutch and lightened flywheel to help put the power to the ground a lot quicker. -------------------- 95 Toyota Celica GT

It all depends on drivers...not cars...IMO..;] Anyways, it should be fine unless you plan on racing. 18's aren't racing rims... as far as crusing around goes, you should have no problems. |

18's on ANYTHING tend to get flats. Your tires are going to be real low profile, meaning less air is getting hotter. And smaller things can puncture them. Check the airpressure constantly. I dont kno what kinda rims you got, but my Focals were a helluva lot heavier than my stocks and you could definately feel the difference.

But on low profile tires, you have less tire, even tho its a lil bigger.
Its called inertia...theres more to spin so it takes more power. This post has been edited by Supersprynt: Oct 3, 2003 - 6:11 PM -------------------- |

The problem here is unspring weight.
The rotational mass to turn an 18 is more than a 14 due to weight and radius of the rim. If the 18 is the same weight as a 14, then the performance maybe be the same. It is like lowering the car. You see how much different it makes in handling the speed. Checkout some physics! You will see why. So to come back that, and increase of hp or tq, especially tq to solve that problem. Thats why when you are moving (if you notice,) it kind of hard to stopped!

rims just weigh more then air... which is what your reducing with bigger rims... you may be burning your clutch if the engine revs and you dont go anywhere... get a stronger clutch, or better yet, dont race in an ST.
