I think it’s the perfect set up for our local B roads, with Cayman R front precision, handling capability but a bit more damping compliance and rear stability than a R.
Hey
@ecarca
, those look like great numbers for a spirited B-road setup—and you're right to be happy about that perfectly even caster! What specifically were you trying to improve on from your previous alignment? I'm sure others would be curious to hear how the car feels with these changes.
What I’ve generally seen on our cars is that front negative camber is greater than rear. Is there a reason this is the other way?
It’s just a guess, but I would think that the car would understeer quite a bit?
I could maybe have gone more aggressive with camber in the front, but the point is I am not optimizing it for track but for the road, and wanted to keep a balance similar to factory, but more oriented towards
Cayman
R stock values, still taking into account the following.
I have lower ride height than a stock S, thanks to the R springs, and more compliant shocks. I should get the sharp turn in with the toe. Also the caster as it is (not adjustable) should get me more dynamic camber and more front grip. Last, with the CSC7
tires
, I need to be in a sort of sweet spot (not too low but also not too high), they take less than say PS4S. So think about it as a system.
There should be more understeer than if I was running say -2.0 in the front, but it's not obvious, even on spirited drives. And I think -1.8 or -2 or anything above -1.4 or -1.5 would not suit the CSC7. As it is, it's really quite able. Last we also have several quite wet months with heavy rain, and I believe it will still perform really well in the wet. To be evaluated soon
All in all, I don't think I would really get more grip, for my particular setup with more front camber. That would probably reduce stability, negatively impact tire wear and not necessarily improve the turn in because the toe and caster should already achieve that.
It's quite theoretical and I hope it makes sense. I don't really push that hard on public roads, but so far it seems to make sense behind the wheel.
