Okay, took my DC5 to Winton on sunday.
Quick review, these coilovers on full dampened settings in the rear end (not sure how they would go if you had no bracing) combined with my Rear Strut Bar, Upper bar, C-Pillar bar, front sway bar and front strut.
These are incredible, if you can find a reasonably priced used set, i encourage you purchase as i said earlier. Was beautiful on track, had only -1 Camber Front and -2 Camber in rear.
They not incredibly rough on track through bumps but through the corners, i don't know how to explain it but when i turned the wheel, the DC5 went wherever i put it, didn't fail on me once. Never was a custom to coilovers before purchasing Ohlins DFV for the DC5 but now i would recommend them to everybody i know, the quality is typical JDM but the history backing them up shows there quality.

If i was going for a full track spec car, i wouldn't be opting for the springs rates of 8kg front and 10kg rear for the price of new, make sure you customize them or i would suggest Tein Super Racing instead.
Overall, money well spent on these coilovers, very good on track but that's my opinion. Only thing that let me down was my tires. If your going to ask for a time i set, don't bother, was a fun day off
