I Installed skunk2 full coil overs & SPC lower control arms and after it the car feel's unstable, anything over 80mph and running threw gears the car wants to pull to one side hard

I noticed my trailing arm bushing's are a bit warn and showing sign's of large cracks. could that play a big factor?

the chassis has over 150k so im sure its time for new bushings

should I go with stock or urethane? anyone got some good replacement kits they recommend?

 

Did you get it aligned after you put them on? Which way is it pulling? What condition are your tires in?

 

did you get it aligned after you put the coilovers in?

 

No havent got it aligned yet.

tires are brand new

It just feels like the *** end wants to come around doing slight lane changes at freeway speed, when i push the car side to side its solid as a rock only thing that moves is the 40/17 series tires lol

im thinkin it needs an alignment and new bushings/ball joints.

SPC lower control arms are shorter than OEM. that makes the rear less cambered. less grip in the rear.

plus, you need an alignment since you changed your ride height.

 

a alignment should solve the problem.

 

Parts are nothing without a proper setup...and proper working parts - replace the bushings ASAP! Think 'package'!

 

You will need to have the wheels aligned immediately, especially while the tires are still new. I'm betting that you're toed out in the rear.

If the trailing arm bushings are broken, you will need to replace them before aligning the car because everything will be thrown off if you don't, rendering the money you spent on alignment a waste.

Check all ball joints. If they have no play, then they don't need to be replaced; if there is any perceptible play, replace. Check bushings, and replace any that are broken or deformed. You won't need to replace all of them. Don't bother with polyurethane.

well yeah I just had to replace my rear tires WAY PREMATURE.

The above post is correct I am Toe'd out big time and that's why its unstable at highway speeds.

Can they align my car with the stock setup? or do i need pieces to ajust the Toe/Camber?

What is a good kit for bushing replacement? urethane? (energy?) prothane? (p-s-t.com?) or buy the Spherical bearing conversion for front and rear?

 

camber kits aren't really necessary. just have them set your toe to zero and you are set!

The toe can be adjusted using stock/oem arms. Camber is not adjustable in stock form.
