Anything bigger than 8mm would be out of the arch, my wheels are slightly wider. I was running 15mm spacers on my standard Ronals with no scrubbing at all.

I've put a deposit down on some KW Variant 1's.
 
I haven't been about much, just sitting on the drive cleaning arches!:lol:

Every time i see a red Leon i think it's you but i don't know your reg, so i have to look at the wheels and by that time it's too late anyway!
 
lol probbaly is me haha
what you doing to your arches wanna do mine?
 
Yeah, i just cleaned the arches.

The 8mm spacers seem fine on mine, Ben had them on his and it scrubbed, but i'm running a slightly lower profile tyre:)
 
After checking part numbers on the coilovers i was getting, they've turned out to be the wrong ones for my car.

So now i'm going to to trackrods and ends, then put the money torwards a Quaife diff :)

Still on the look out for a cage too.
