Yes, and yes.


The 3 strut hat bolts bolt into slots on the strut tower. Removing the alignment pin, loosening the 3 nuts, and sliding the strut hat more inboard gives you ~-.6deg (approx.) for an unlowered car... more if lowered.

The slots only allow about 3/8" travel, but allows you 3/8" more room on the fender side, for rubber.

Wider tire, plus increased front grip. On MacPherson cars when the struts are under compression, the wheel will go into a positive camber state, causing you to ride on the outer edge of the tire. This results in a smaller contact patch and less grip.

By adding more negative camber, you will have a larger contact patch under compression and more grip in the turns (which the 1 needs).

Free camber mod is easy:

  • Open the hood.
  • Loosen, but do not remove, the 3 bolts each on top of the strut towers
  • Remove the centering pins. Use big ass pliers . . . you may have to drill them out (the dealer did on mine.)
  • Stick a closed ended wrench into the hole on top of the strut tower and gently pry the rubber strut top towards the centerline of the car. You should get about a half inch of movement.
  • Retighten the bolts to 34 N*m
  • Go get an alignment, as you toe is now likely borked.

A decent alignment shop will do all this for you if you pull the pins.
