I know that the front of the evos sit a little higher then the rear. Is there a specific guideline or ratio for the height difference? I am redoing my suspension and just want to make sure that my height adjustment from Front to Back is correct.

Any guidance is appreciated.

Look at your virtual centers and it will become apparent.

measuring from the side rail jack point, my rear is about .5" higher than front.

Call it a rake. It is important for handling. Different hight front rear or equal is important for a race - set up and the surface you are attempt to run. It should be a part of tge wheel aligment you get or you do.

Its a bit of an illusion. The front fender gap gives the appearance the front sits higher, but its not.

Read this thread if you have the time. There are a few experts that chimed-in

Thanks for the the link. Some good info for sure that will be helpful setting up my car for next season. I would like to see some more input about corner balancing and rake.

I try to achieve a level "looking" rake. I then Corner Weight the car with the car in its "race" mode (Gas tank half full, me in car, ect...). And last, I do my alignment.

My CW:

I shoot for the front left/right to be equal more than a 50/50 cross weight.

^ very similar to what I ended up with, but your front weight is a bit lower than mine. How much do you weigh?

Great thread, going to have to re-read that when I have time.

The only thing I think I really learned about setting up an Evo this year, is if you're going to do anything to the diffs, do that first, and then set up the suspension. I just did the OEM re-arrange and it had a really profound affect on the car, to the point where I feel like I have to reevaluate a lot of the suspension choices and see if they still make sense.

^ Lol... Thanks for all the input guys. Keep this going. Lot of good info being tossed around here.

IMO... I set the instant center of the fronts where I feel is optimal based on kinematics, because it's the grip limited end of the car. After I set the fronts; I adjust my rear roll center to achieve the desired "flick-ability."

I need a custom set of uprights and then I'll get the front end super low....and bring the back end with it, bringing my CG instantly lower.

Let me know when you figure that out. Until then I'll be rockin' the drag launch appearance while sitting still

I actually have used a similar strategy for my ride height. I set the front based on suspension geometry and then messed with the rear to get the feel I wanted. Going to have to redo this spring after the whiteline roll center kit goes in, but will start at last years end point.

I've got it figured out... I just need to money to buy a huge chunk of 7075. I've got a 5-axis Mazak awaiting material...
