this is from someone who does rwc..
"coilovers are acceptable but there base height ajustability cannot be below minimum clearence ie: 110mm , they also have to have soild tops no camber or castor adjustability is allowed and to top is all off no pillow ball mounts or dampning adjusters... and the spring rates must be to oem standards
lol it pretty much excludes 99.9% of coils"
