autocross alignment done
Got my alignment finished today over @ FasTrack
Great place, a pro shop that can deal with custom suspensions no problem.
Car was aligned weighed, so it would be correct with me in it.
Set the ride height 1st.
Stock is
7.8in front & rear
I set mine @
6.25in front
5.75in rear
which actually makes the wheel lip clearance even.
Camber, I decided to go ahead and crank up the camber since I have my truck for a daily driver, and I like to autocross.
Front
2.5 degrees
7.0 degrees caster
0.05 degrees toe out
Rear
2.0 degrees
0.20 degrees toe in
I managed to get that much caster & camber with the much ride height because I have adjustable a-arms on the front.
Previously, I had the car 'in the weeds' but this made the top a-arms angle UP, stock they angle DOWN, so I knew that couldn't be good for geometry.

just got the 500 miles on it
putting a bigger overflow tank it in
we tried running a smaller one but it wasn't working out.
fortunately Vortech still had some despite the kit being discontinued.
The brown van arrives tomorrow

Nice! I just got mine aligned as well. I cut down the conical spacers but the camber wasn't even per side. The inside of the tires is getting worn down pretty fast street driving. The car turns sooo much better with the camber!!! I could not get that much caster with the stock arms. This is the most:

Doing some more research, it turns out stock is an anhedral suspension geometry
The IC is on the outside.
Which of course changes when the car is lowered
