In Sa height adjustable suspension (coilovers) are not allowed. the only way you can have them in your car is to weld the adjusting nuts...... which makes having coil overs useless. Just out of curiosity how many people on hear have coil overs? and if you do when you corner weighed your car were the weights pretty good to start with? did you move much weight around to get them better?
on the other topic they would probely at least like rear discs.
