I see the under ride and the over ride and then there is also the oldschool kind that you can get from pep boys. They are all the same price but which is the way to go.

I have a 5 leaf mideye spring and i am running 17 in wheels if it makes a difference.

Also, a couple days ago i completed the shelby drop and installed 620 springs and kyb gr2 shocks. the passenger side is sitting about 1/2 lower than the driverside. Should this settle?

I love driving this car!

 

Did you torque down the UCA bushings with the car on the ground, or in the air? Or did you just bolt them back in as-is? UCA bushings need to be torqued with the car on the ground at rest height, otherwise you preload the bushings which can cause ride height variations.

Otherwise, I'd wait a month or two for it to settle and see what happens. Where'd you get the springs from?

Traction bar wise, avoid the cheapo bolt-on types. I'd recommend quality Traction Masters under-ride traction bars. They are the OEM for the original Shelby units. Cal-Tracs are another option, but they're pricey and overkill IMO for most street cars.

 

If you have orig spring perches one could be worn down more than the other. Unlikely, but something to check out.
