i have the 20mm whiteline Ive thrown my car about the arse end has NEVER let go it sits on the road nice and flat round corners totally reccommend these bars.
cars with little weight in the back are far more susceptible to oversteer and the rear letting go due to lack of unsprung weight over the rear wheels. If you have rear seats etc in the back and full interior then i would go 20mm. Tbh 20mm shouldn't be a problem anyway, its when people put the 22mm on the back that it starts becoming an issue.
