So I just got a eg coupe and threw on some ebay coilovers and spc lca's for the time being. I don't know if this matters but its slammed in the back and and the tires are 205/50/15's. At about 50 miles per hour the back of the car becomes real unstable and driving on the free is near impossible. Any idea's on what this could be?

 

If you have not gotten an alignment after installing the coilovers, that may be a large part of your issues.

 

Yea I haven't gotten an alignment yet. Ill see if I can get one tomorrow. Thanx for the info.

 

Your issue is your ebay suspension. If you go cheap it will run cheap

 

Did you have your wheels balanced

 

so i tried to get an alignment today and the technician at my work told me that my car was to low to align. i took off the front bumper so the 2 arms on the alignment machine could see each other but it was still to low. so he raised the car up a little bit on the lift so it would work. he aligned it and the problem is somewhat fixed but not perfect so i think im going to take it to les schwab and see if they can help me out. and no i havent gotten the wheels balanced. if they are out of balance that usually just causes vibration.

 

I'm guessing your ebay coilovers are slip on's. Most likely you need new shocks.

 

raise the car. or try to find a place that has an in ground alignment machine. or you can DIY by careful measuring and using string lines.

 

I WAS THINKING THE SAME THING

 

maybe you just shouldnt lower it so much?

they dont handle as well if riding on the bumpstops.
