Coilovers, upgraded bushes and adjustable drop links are the minimum when lowering in my eyes coilovers can be adjusted to ur driving prefrence had springs on the last car and was ok done coilovers on this one n what a diffrence for track I'd say go with that n if u have standard rays atm keep them as they r lighter n better for track
So u can set the car up for show on road nice 19" alloys n soft ride coilovers and then light strong rays on track with firmer suspension by using coilovers
