The guy who did my LS2 tuning recently bought a new alignment rack. This thing is so cool. It can measure bumpsteer, check if the chassis is square to the body and a host of other things. I guess it cost over $50k installed and uses digital cameras on targets. The technology and graphics were stunning.
Anyways, the best news was that my car is perfectly square.. to the hundreth of an inch.
And even though my car is a bit lower than optimal the bumpsteer is very minimal. Almost none in a rise and very slight to the right on a compression (1 inch each way).
Sorta cool:
My thrust angle was at about 2-degrees so we brought that to around zero. Scott was impressed with how easy the LD three-link was to adjust. We went for a good performance street alignment since that's where the car will spend 90% of its life.
The final specs:
The alignment wasn't cheap but I feel it was worth every penny. The car tracks dead straight, doesn't "hunt" the ruts in the roads and feels great. We also did some computer fine tuning and figured out my front squeek. When I had my alt bracket powdered they coated the nub where the idler rides by accident. I cleaned it off, but not good enough thus causing the pulley to ride at a VERY slight angle. This causes the chirp. I will order up a new brackt tomorrow and just paint the damn thing. lol
I also found out that my car runs out of gas at 1/2 tank on the gauge.. don't ask but I need to adjust the sender.
