Tein HE's. Amazing coilovers. Your tyre setup and sway bar setup will determine quite a bit. But if you just wanna slap something on there and get a great change for the better then HE's or the new Drift Spec c/o. Just make sure you've got some quality tyres up front, and maybe some tie rods and ends. Those two things made a huge difference for me. The extra steering angle is a godsend. Non stickies up front = understeer city. When I first started drifting I took a 90 degree corner like the noob I was and plowed all the way through it into a shallow ditch. Not even a clutch kick saved my noob ***.
