I have a 04 ep3 with Megan coilovers and am having a problem with the rears. I measured both before I installed them, both being perfectly even.

Now that they are installed, I can fit a good finger in between the tire and fender one the passenger side where as the driver side I can't even fit a pen in between. What would cause that and how can I fix it.

 

Normal

Adjust the sleeves. They aren't ever going to be even.

 

Would It be better to just set them measuring from the wheel center to fender?

 

doesnt matter.

adjust it however you want. your car is not symmetrical after 10 years of driving and an already uneven weight balance.

youre missing the point in adjustable sleeves....

 

I'm sure Megan has extremely tight quality standards on the consistency of their products.

JK. They don't.

Make sure you're on flat ground. Adjust the height how you want it. It's not uncommon for 2 sides to be uneven. The weight distribution of te car is not 50/50 side to side or back/front.

You'll need to adjust them again in 500-1000 miles after they settle.

If you didn't clock your bushings, you'll need to adjust the height again once those bushings weaken up or tear. Lesson being that you should clock them now. Maybe the heights will even out...and your bushings will last more than a few months.

 

Hi, how do you clock the bushings ?? Thanks

 

the stock rubber bushings are made of a inner metal sleeve and an outer metal sleeve. there is rubber filled between the two and bonded to the surface of both sleeves. the inner sleeve can only rotate so much relative to the outer sleeve because the rubber only allows so much stretch. it also stretches elastically, like a spring. bushings actually contribute to the spring rate of your suspension. when you tighten the bolt to the bushing, it locks the relative position of the inner sleeve to the outer sleeve, plus the range of motion and spring force the bushing allows.

if you do not reset/clock your bushings, then the bushing is forced to be in a stretched position most of the time at an outer range of the intended motion, instead of resting at the middle, unstretched position. and once you over stretch the bushing, it loses its capacity to stretch and breaks the rubber like a rubber band. which is how you easily kill a bushing. gone is the spring rate of the bushing and will likely deteriorate faster and cause slop in positioning the inner sleeve concentric to the outer sleeve.

to reset your bushings, put the car on 4 jackstands. take the wheels off. loosen the suspension bolts. put a jack under one of the suspension corners and raise it until that corner is off the jack stand. bounce the car a bit. then tighten. dont forget to tighten every bolt youve already loosened.
