Its not bad, its just harder to work with. You have to raise your roll center the lower you go.

Its just more of a pain in the ass. But it does have a larger increase in camber gain then most would want under compression. Its useable up to a degree. But most racing set ups ditch it for the ease and adjustablity of an A-Arm set up.

I posted up a Double A-Arm rear suspension conversion for 240s like 2-3 weeks ago. Its 8k from japanland. Its an entire subframe and link set-up. Its bad ass. Then all you have to do is convert the front to double wish bone from a skyline or custom a-arm and your set for ultimate grip.
