The difference is in the damper and suspension settings.Apparently they feel quite different to drive. Not sure how best part of 200 brake in a pretty light car can be slow? It's all about being to exploit everything you have and have brilliant handling. If you are a decent driver, than the GT86 will reward you by it's handling and balance, an average point and squirt driver would find it slow and uninspiring. Loads of people have spouted on about fitting a turbo to it, BUT, if you want to enjoy the balance and on the limit oversteer etc, then a turbo would knacker all of that up.NA cars have instant throttle response, perfect for neat and precise driving and controlability,turbo's are really only any good for straight lines and top speed.You pays yer money and all that............................................
