performance in all categories has decreased.
What have you guys done to remedy this problem? I can definitely tell I need lowered now more than ever because of the hightened center of gravity. My tires currently are 215/50/17....hopefully some 215/45s will give me a bit more of my power back. blah. |

Also like to add that it made my steering feel a lot heavier...I know this is just because the wheels are heavier, but it doesn't feel good.

I went from 14" steelies to 17" wheels, so I know what you mean. 215/45/17 tires would probably improve the areas of complaint in all respects.

I'd say a smaller tread patch... If you think about it, the contact patch on a 215 is huge. Lower it to a 205 and you should have a better result. You can rock a 205/50 comfortably since it's a balance up from OEM size. I'd never go wider on a tire than OE spec, but if you go taller, always go skinnier. Same rule applies to wider. But, regardless 215 is a large tread.

changing to a 45 won't make much of a difference. most of the performance loss comes from the weight of the wheels. lightweight and smaller wheels will give you better acceleration, braking, and handling. 17s are mainly just for looks. when i switched to 17s it made a noticeable difference and the car felt a lot slower, but after a while of driving you get used to it.

hmm why did you get 215/50R17 in the first place? I'm assuming to fill the wheel gap.
get your self some 215/45R17 tires and lowerings springs and you should be set. -------------------- Group buy to replicate Narrow E series transaxle parts

When I put 17s on my Celica I didn't notice a single bit of difference in performance. It's more the weight of the wheel than tire spec. It's more rolling mass that your car has to get moving. I'm running a 245/35/19 and 275/30/19 on my Lexus, the performance aspect is phenominal!!! Ride is a little rough due to almost no sidewall though

I used to have a staggered set of 18's & the acceleration went downhill, but I got accustomed to it. After a month or so, if you are still bothered by it, switch back to smaller wheels.

From what I've read the 17" matrix wheels weigh in at around 27lbs for just the wheel. The stock 15"gt wheels are between 16.5-17lbs each. So that's a big difference and your acceleration, handling, braking and gas mileage will suffer. I went with the 17" tC wheels which weigh in at around 21lbs each. Your choices are either live with the wheels you have or swap them out for something lighter.

The wheels I'm looking to get are 18's and they weigh in at a little less than 22 lbs. There's your problem. The power from your car is being sucked by the weight of your wheels. |

regular OZ wheels are about 8 kgs and cast wheels are around 10-12 kilograms..I dont know about you but I think 17" is the best there is in relation to looks/handling/performance when it comes to taking it to the track...i put 225's 17 55 on the gt four and It is a relief to not skid around and get amazing launches...But then again second reviews to come when i finish the beast, still got to put the whole thing together with new suspension and a diff cushion

Be prepared to continue being disappointed because the weight is still going to be substantial; I'm running 215//45/17 on tC wheels and the combined weight is about 40 pounds at each corner compared to the stock 15's on 205/55/15 weighing about 36lbs.
At this point, knowing what I do now if I had a chance to do it again I'd either choose 16" GT-S rims or pay for very light 17s. Good luck. This post has been edited by Keiri: Jul 25, 2011 - 6:42 PM -------------------- Has no more Celicas
