Optimal toe for daily/occational trackday
Had my car in at the dealership after I lowered it. They are technically within spec, but the toe is as close to 0 as they managed, and as a consequence my car is very nervous at speed and VERY sensitive to any ruts and poor roads.
What do I want to aim for for a nice stable high speed setup? I'd rather sacrifice a little turn-in to benefit motorway stability. |

What are the actual specs you ended up with?
0 front toe and about 1/16" rear toe in isn't unstable on the highway, sounds like you might have some toe out?

@atledreier Being sensitive to ruts typically has to do with camber, not toe. Your tire isn't sitting flat on the ground to just go over the grooves. Instead it is cambered in and will be more likely to follow in the grooves.

Measured values after the alignment:
All values are left/right side and degrees Front: Caster: 5:48/5:54 Camber: -0.24 / -0.36 Toe: +0.03/+0.03 Rear: Camber: -1.54/-2.24 Toe: 0.0/0.0 So, it seems the front toe is actually very slightly positive, not sure if this is out or in, it doesn't say. The spec says minimum -0.45 and max +0.45 degrees, again, doesn't really give me anything to determine if it's in or out. The rear camber stands out as very uneven, but apparently that was the best they could do with no adjustable rear arms. The car is lowered just shy of an inch, and I run 20mm spacers front and 25mm rear. Stock wheels, 225/45-17 Michelin Pilot Sport 3 front and rear. |

You want a bit of toe in at the rear for stability. Probably should get some rear LCAs to fix the camber.
