Wheel alignment and pulling while braking

MaysEffect

Other than the rear camber being too negative, nothing is unusual. The toe setting will change with camber adjustment, so finding a competent mechanic that wont flip out when this happens is important. I'm not going to advertise spending money on adjustable control arms.

Unfortunately steering wandering under braking and cruising is just a nature of the car do to the low caster and anti-dive design. Increasing Toe-in on the rear will help marginally.

Keeping some additional weight in the rear should help a bit too. Just depends if you want the weight penalty.
