Is rolling the only answer?

Right then, who can help me out?!

On my mk2 saloon i have alleycats 13x8s 185/50/13 dunlop sp2000 tires.

Only trouble being the offset on alleycats is for a mini/rover so they stick out the arches a good inch at the front and probably a little less at the back.

I'm currently running a 60mm drop at the back and about 50mm at the front but they scrub wherever i go and having people in the back is a definat no.

I wanna run like an 80mm drop or something but think its gonna have to be time to sell these wheels and get something with a vw offset or have the arches rolled which is obviously a headache and would probably mean flaring aswel to accomidate the fronts which would in turn mean losing the black plastic arch trims.

Unless anyone knows of another option that could keep me with these wheels and go lower???? Any advice much appreciated!
