After some advice and help please.

I have 8x17 on the fronts with 205/40 tyres
annd
8.5 x 17 on the rears with 215/40 tyres.

I am using Ahmed Bayoo coil spirngs with Konis all round.

However I find that it still catches in places on one side of the rear and on the front.
The passenger side is find and never catches whereas the drivers side does as I can see where it nips the tyre.

On the rear it is sat up quite high, but I suppose under load it sits down more and catches on the front of the rear arch.

Apart from cutting the arches is there anything else I can do?

As for the front I dont know why it would catch only side.
