As the title says, does adding more toe in at the rear (say 1mm to 2.5mm per side) increase your traction on take-off? Reason I ask is, just two weeks ago when I had my 18"MPSS (225/255) and 1mm toe in rear, I could spin wheels in 1st and 2nd gear while rolling at 40km/h. Now with my 19"MPSS and 2.5mm toe in (same 225/255 widths) I am finding it very difficult to even spin in 1st while rolling. (Obvious factors have been checked, DTC completely off, boosting healthy etc.)
Any ideas?
