Camber: does this look right? (track video inside)
 

...videos from Willow Springs track day 2 weeks ago.

kep points:

-2.2* camber -- alignment done right before track day
Global West control arms
ATS AFX spindles

need further info?

We were surprised to not see more dynamic camber in this video. Any ideas?

Thanks

Kinda hard to actually tell... from the vantage of the camera.

Just sitting still from that vantage... doesnt even show the static that you have dialed into it. But in motion... it does look as if the tire had enough camber in it to address body roll and the suspension compression.

You dont have any tire temps do ya ?

Hard to tell, it looked square in the well..............the best way to measure would be with tire temps across the face of the tire......and on that note the worst way to find out is when your tire is bald on one side, lol.

Yes tire temps were recorded throughout the day but that folder is in the car and I am not with said car. Will have them later tonight and will report back.

Thanks guys.

Ok got temps for you guys. CCW track.

1st session -- warmup

Left Front: Outside to Inside = 88* to 89*
Right Front: Outside to Inside = 100* to 100*

Left Rear: Outside to Inside = 87* to 89*
Right Rear: Outside to Inside = 114* to 110* to *103


2nd session -- litte faster

Left Front: Outside to Center to Inside = 100* to 107* to 108*
Right Front: Outside to Center to Inside = 117* to 116* to 113*

Left Rear: Outside to Inside = 105* to 109*
Right Rear: Outside to Inside = 108* to 106*

3rd or 4th session -- full boogie

Left Front: Outside to Inside = 100* to 106*
Right Front: Outside to Inside = 132* to 127*

Left Rear: Outside to Inside = 106* to 106*
Right Rear: Outside to Inside = 122* to 117*

Over the sessions we also gradually brought tire pressures down from 35 to 32 psi cold, and they were gaining about 5 psi per session.


Comments?

Hmmm.......first thing first, are you experiencing any under steer? If not, a little more neg. camber might help. When I ran 255/40's up front I ran -2.5 camber. Where are you at now?

Yes there is some. And if you don't believe me, Mary P said after driving it at Marina "this thing pushes like a dump truck!" :rofl:

Camber is now at -2.2*. We aligned it a few days before the track day.

I thought that was before the sway bar..

Nope. I've had the sway bar for every autoX and road course I've done.

I never thought the understeer was as bad as Mary thought, but what do I know? I have no baseline.

315's in the rear with 245's up front doesn't help but I know 275's in the rear are not an option for you.

What front and rear spring rates are you running? Adjustable shocks?
