The offs, nothing more than sliding across some grass, gravel or maybe a bit of tarmac.
Most UK circuits don't have ridiculous bumps, besides bouncing off them doesn't tend to be the quickest
I've said this countless times but when I smashed up 2 Regamasters it was enough to crack a driveshaft, bend a subframe and controls arms, and take a chunk out of a solid concrete kerb. The wheels were bent but still held air and got me home. I guarantee Rota Slipstreams wouldn't have taken that. Not at all. They would have shattered and I'd have had an even bigger bill to pay.
You can harp on about quality and how yours haven't broke blah blah blah day in day out, fact is the originals will always be a better quality. You can't escape that. Personally I've never been to fussed for the quality arguement, but I've been dragged in through my own personal experience.
The other argument of "scene" boys don't like people copying, well that cracks me up. There's only a finite number of wheels and mods to a car, and at some point somewhere somebody will do the same. It happens. f**k me, this is the forum that at one point berates everybody for being sheep, then the next is celebrating how good clios look with the same mods.
What sucks is that Rota and the like can get away with ripping off designs and people support them "Because they're cheap innit". Eventually, the big companies will go tits up and then what? Rota will get their copies copied and it starts again and the cycle continues. It's s**t.
