Default track car - alignment. what do you think?

Just got the track car back from alignment and got the Hunter printout attached.

Wow, was your front toed-in before. And with the rear toe and front caster all uneven, the car must have been a a handful. Ready to race now.

the only thing to do is go out on track and see how it handles. keep a dairy of tire pressures and temps from the inner, middle and outer sections of the tires - front and rear. i predict you will have trouble getting heat into the outer third of the rears with this much camber - its what im running and thats my experience. im less certain on how much rear toe is required, it seems opinions vary. did you get the alinement with a half tank of gas or a full tank? this can affect the rear geometry quite a bit.

i think the front can probably take more camber for an all out track attack but otherwise i like the front toe and im guessing you maxed out the front castor? it seems some cars have more ajustment here than others.

Yes, almost ready... just need a gearbox...
but I got a hot lead on an '85 LSD box.
I replaced the steering rack, that's why the toe in was way off.

yes, I maxed out front values, was shooting for 5 degree of caster and 3 degrees of camber...
the tank was half full and no one in it...
So I need to buy a temp gauge.

thanks,

For anyone in South Florida by the way, Expertech in Sunrise is a great place for alignment. They have a Hunter 600 alignment rack and charged me $107. took them about two hours.

$107 for 2 hours on the rack - absolute bargain.

you need way more camber on the front. the toe on the rear seems out of whack I run .15 degrees/side

the only way I will get more camber in the fron is by changing upper A arms and that is not in the budget for now. At least that's what I have found out.
I was told to start with no toe in the rear or a tick of toe in to start and take it from there.

you dont need more camber in the front. both anderson and i took much of the camber out of the front and rear and got better handling and wear. ESPECIALLY Anderson, who had a bunch more camber in the rear and was real loose and was burning up the inside edge. im near 2 degrees on all 4 corners.
rear toe might make you a little loose under power. (that coupled with the 2.5 degree rear camber)

remember, you are not setting up a 911 or BMW

You will see at the track.

The 928 doesn't need nearly as much camber as a car with regular struts.
