My 2003 evo with 74k miles sits a tad bit lower in the rear on the right side than the left. Maybe a quarter or a little less than a half inch (cant tell by eye). Car has lowering springs (sport comp) or something. Car drives straight at all speeds on nice roads, but with two fat friends on the right i can feel it but i think thats normal. Car was mostly stock its whole life and autocrossed a little. I had an alignment recently. Is the suspension just worn??

 

blown strut?

 

I don't think a strut would affect ride height, its most likely the springs, how long have they been on? Any visible compromising rust?

 

^^^you seriuos? have you seen a vehicle with a blown strut? your wheel to fender gap increases.

 

So your saying a blown strut increases wheel gap? I don't think so....

 

A while back the back right was squeking a bit then it stopped, it dosent really affect drivability like i said i can go high speeds with no hands sometimes tracks perfectly straight. How can i tell if the springs weak?? The previous owner put them in

 

Steel cold wound springs "settle" during their life. Easy way to check would be pull the rear springs and swap them.

 

Are those the type of springs i have?? I will the find the exact name when i go home im pretty sure they are your typical lowering springs

 

They are racecomp engineering GTworx springs, the right backs like 1/4 inch low. Can the cause go as far as rear bushings being worn or something along those lines?

Probably springs. May need to replace them or re-check installation.

 

Are you measuring on a level surface? Not one that looks level, but a place that has actually been leveled? Cause just measuring in your garage you will be off by significant amounts left/right and front/rear due to sloping and concrete settling.

Also, the spring rate of the GTworx are around 330 rear with a M.R. or ~0.91. That gives a wheel rate of ~270lb/in, a difference of 70lbs left/right will give you a 1/4" difference. The evo rear is pretty well balance stock, but if you have a sub on one side or measuring with a driver that could cause a difference.

 

I measured with my car facing both directions in my garage the right rear remains low the fronts are the same. Trunk is completly clean no subs or junk. Maybe if i put a full tank maybe the left one will go down and match the other side???? I just dont want there to be any misignments with body but i cant even see that being a problem

 

In my eyes this can be the result of a couple different things.

1. Your garage inst perfectly level
2. Your right rear strut is blown
3. The weight balance of your car unfavorable.

Given the fact that you said its not your garage and the known general weight distribution of evos, I would put my money on a blown strut.

Others mentioned the integrity of your springs and I am willing to bet that its not an issue with your springs. The GTworx springs are a quality product. If they were to sag which they will do initially but very slightly there is no way one side has sagged a 1/2"

 

Make sure you're on a level surface. We've also seen side to side variations in stock EVOs plenty of times. Check your rear shocks for leaking fluid.
