Yes you have to take some off the rear toe block to put the anti squat shims in.only 5 mins work with the dremel.
The Gen 2 has a raised gearbox compared to the Gen 1 car so you don't need to take much at all from the arms, just test fit them and take a little from the original diff outdrive cut away.
Hope this helps
