as it sits it looks like the drivers side is a different angle than the passengers side. maybe my eye. it would be good to talk with a front end alignment guy and see what he says. also, check the geometry on the spec sheet for whatever front end you have there and set it up according to what is correct for that set up, then decide if the stance is what you want. if not correct it by getting the right spindle set.

Thanks for the response! That a corvette k member and veter a arms and spindles. I set the truck on jack stands so that the bottom a arms were level to the ground and then install the brackets and coilovers as I let the truck down on the ground it came out with the a arms not sitting level and being about two inches to high. The only thing I can come up with is I need shorter shocks and springs? With the truck sitting on the ground my shock has 3 1/2 travel up and down! But my spring is as low as I can get it.. What do you think now?
