My Dad has this one...
The performance on the road from 30-140 was IDENTICAL to my RS when standard, but it's a different story now mines tweaked. It doesn't feel stupidly fast but isn't slow by any means. I'm sure 0-60 is around 5.5 and top end is 155, but Dad's slows down considerably past 140 tbh. He has been round Dono in it, I was passenger, superb go-kart like handling, very well planted + responsive, really fun car, brakes only lasted a few laps before serious fade + 'long pedal' though, would get some good pads + fluid in there. Absolutely love the car!
