I put eibach springs on my gs today and still have the stock wheels on. My aftremarket wheels will be here next week and are 20x8.5 with 245/35/20 tires and 20x10 with 275/30/20 tires for the rear.

I want to get my car re aligned but my question is what is the diameter of our stocks wheels vs. my after market ones? Are they close enough to get the alignment done with the stock wheels, so my aftermarket ones dont get scratched or dinged and then Ill just put my aftremarket ones on ?

 

The stock 17's are 25.32" in diameter

the 245/35R20 are 26.75" in diameter
the 275/30R20 are 27.57" in diameter

 

so is that a no on doing the alignment with the stocks?

 

yeah wait for your 20s before the alignment
