The only thing that makes them perform like shit is the camber and stretch on the tires. Anyone who doesn’t own two sets of wheels is a ratard and anyone who has 4*+ camber is either on bags and doesn’t give a shit about handling or has adjustable camber in some form and can throw it back into normal specs in an hour.
If I ever get back into autoX in the MR2 all I’ll have to do is buy another set of K1s or the equivalent and I’ll be ready to rock. I’ll only have 2.5-3* of camber so that won’t be too dumpy.
