I disagree with the previous statement about locked 2 degrees of toe. You have to put shims in the rear arms to adjust the toe - but that does also affect your track width at the same time.
Perhaps I worded it incorrectly. On the EVO2 both the front and rear hinge monts for the rear arms necessatie the addition of shims to achive rear toe adjustment. On the T1R, the front hinge mounts, on the rear arms, are larger then the rear ones, thus negating the need to add the shims, of course you can add more shims to get more rear toe but you can have zero deg rear toe on the EVO2 (not that anyone would want it), but it's not an option on a standard T1R.
The only accessories for might need for either car is a front roll bar and a one way diff.
