I know we have a thread on this but I want everyone with wider tires on the rear wheels to help me out. So i dont want people saying that same size all around is better. You can do that in the other thread. I just got my Volk LE37T put on 8.5 in the front and 9.5 in the rear. I dont know if the shop aligned the car again or what but my understeer is terrible. I have Tein coilovers and with my bald OEM tires with 20,000 miles it handles very well. And now with new tires the understeer is terrible and I feel like I am driving an SUV. The car feels like it is swaying a lot of the tires. I know there has to be some way to eliminate most of this problem because a honda element could out handle my car right now. So if anyone has some alignment specs or any other adivse they could give me I would greatly appriciate it.

p.s I will get the pics of the wheels up soon. They are the LE37T in gloss black. SO NICE

What kind of tires are you running? the volks you sold me work just fine. It seems the same to me. i haven't lowered the car yet but now maybe i won't .

Im sorry to hear that you didnt get what you expected. It all ways sucks when that happens (and I have lots of experience with not getting what I expect ) I am sure with a little tuning you can get the car back into shape

First, I would suggest you check behind the front wheels and make sure every thing is connected. Something sounds very fishy. Did you have any other work done? Also just eyeball the camber and toe. To do what you are describing, there has to be something seriously wrong (unless you are exagerating, which hardly ever happens here )

When you say that it oversteers, what exactly does the car do? Also describe the corner, too. Does the back end lose grip and whip around hard and sudden? Or does it just drift a little. Also, In my limited experience, SUVs tend to understeer (I am going to resist suggesting that you miss wrote oversteer for understeer and then I am going to resist suggesting that you should expect understeer with staggered tires cause you stated that you did not want that sort of advice )

There is a long long multi post thread with every spec you need for alignment in this forum posted by the moderator with the rotor avatar. Search for that.

Im sorry, i meant understeer. When I turn the car it seems like a delayed reaction and the front nose just slowly drifts to the left or right like in one slow moving piece. It doesnt dart side to side like im used to. Correct me if im wrong but when you turn the wheel the tires turn and bank slightly to that side correct. It feels like they turn flat and I dont have that quick side to side turn like I used to. I am not sliding out or anything but i havent really taken a turn hard yet mostly because im afraid too. I am running Cooper Zeon 2XS. They arnt the best tires but its all I could afford at the time. Spent all the money on the wheels. But im sure next year I will prob just get good tires and sell these ones.

Well if you had bald tires in the front that's what your experiencing now with good tires.

Plus you made your back end stiffer than the front so you created more under steer with wider wheels and tires.

this is what it feels like. A boat. Good answer. This might be the reason but alignment is prob it also. I cant find those alignment specs. I used them before but cant find them now. If someone can find them and post them that would be great. And those specs should prob be made a sticky cuz Im sure a lot of people would use them. Also does the alignment need to be different with the different tire sizes? as compared to the OEM wheels
