i am very aware that you need grip to drift. as the track in Perth is a high speed track.
I have run entry level coilovers (d2) with non-adjustable suspension bits (sway bars, controls arms etc), then i have run the d2 with adjustable suspensions bits.
i have almost run some shock and spring setup (cant remember brand was years ago)
I think you will find that my car is setup for my driving style so it suits me perfectly. When it was driven by the suspension specialist that setup my car, he found the front to be perfect but the rear to be alittle too hard for him and he advice me to drop the spring rate down to 6 or 8 but said it was only worth it if i was really doing to spend alot of time at the track.
Also just to add i run nismo non-adjustable arms, which may people have told me are unless and do nothing for my setup but again i found them to work perfectly and do everything i wanted and i am able to get all the things i want from my setup when i go for a wheel alignment
