I have seen older posts on costs for Bilsteins on all 4 corners and a 1 inch spacer. Would like to know what price is reasonable for the product, install and alignment. I live in Houston, Texas. I want bilstein 5100s set at 1.75 in front with Bilsteins in rear with a 1 inch rear spacer. Got a quote from a place for $850 which includes an alignment. Is that too high or going rate?
