Hi,
I just got my car back from the tyre shop and i suspect that the caster setting are way to high. My car is not a daily driver and i intend to do the odd track day.
Wheel specs: Work vs-ss
F: 18x7.5 +40
R: 18x8.5 +52
Tyres: Kumho XS KU36
F: 225/40/18
R: 245/40/18

Alignment specs:
Rear
L Camber R
-2.3 -2.3

L Toe R
+1 +1

Front
L Camber R
-1 -1

L Toe R
-0.5 -0.4

L Caster R
+11 +11


Should i be concerned with the caster setting? I thought i'd get your advice before taking it back to the tyre shop.
Your input would be much appreciated. i hope i have provided sufficient information above.

Thanks

 

sorry, i should have posted this in the suspension forum.

i have now re-posted this in the right area.

 

11 degrees?! Is that even possible? If true, then yeah, that's way too much caster by about a factor of 2!

 

I wouldn't be too concerned, just seems like a typo or maybe you use different units of measure. It's typical to set camber/toe and then run max caster, don't think they will be able to adjust anything. I'd be more concerned about your toe. Are those in degrees? Seems like too much toe in on the rear and too much toe out in the front.

 

Assuming that toe is in mm, looks ok.

 

Yeah toe is in mm.

Thanks for your feedback guys.

 

I took my car back to the tyre shop this morning and had them redo the alignment.
Rear toe is now set at 0 (L&R)
Caster was dropped back to +8mm. I'm still surprised with the amount of caster. I max i have seen ppl on s2ki run is +7.


ZDan, 1Nate7: Thanks for your help guys.

 

Caster in mm? Would that be "trail" like for a motorcycle? Never seen it presented that way for a car...
