Car is finally done, 441hp at the wheels, newest problem is at high speeds. When at about 135mph, the car becomes wavy, feels like it is being blown around and is difficult to control. I think that this is due to the stock wheels and tires(my bad, I'm changing them) and the amount of air going under the car at that speed. I've heard some ideas to solve this: lower the car, put speed flaps in the front, different tires...etc. This forum is full of experts, please help. What tires are recommended, how has this problem been solved by others(aside from not driving that fast), what do you guys think? Any help is greatly appreciated.

emm first off why would you go so fast and where???
second my car is stable at 132 with stock wheels and tires. I would make sure that all your suspention components are working right. tie rods, upper and lower control arms... etc etc and i would seize driving this fast if this is occuring since it could lead to a catastrophic loss of control.

I have no answers for you as far as solutions, but I do have a question. Where do you get to drive 135 MPH unhindered? (I wonder can you put un in front of hinder?) Anyway, my car is fine (at the track) at 131, so maybe something else is wrong.
edited to say someone beat me to the question...oh well

lowering the car will help a lot. I do not know what you are wanting to do with this car, but if you are wanting torun the silver stakes or something you need to do some other things. Let us know what you have in mind, and we can help point you in the correct direction. Need more info.

i used to run my car to 140+ all the time in miami and it was very stable. my car is slammed at all times though with sticky nittos on all corners. I95, I75, and a few other roads were all prime targets for my high speed runs.

We'll tell you how to make it handle but you have to tell us more about your combo.There are not a lot of marks going around over 400 WHP.I'm thinking maybe 3-4 MAX.
Dennis,Dujuan,the one Dennis built for that guy,Todd on the 200 shot.

Mine and Dans USED to be.
Who am I missing?
