A few more this morning, one turn drop at the front. I am going to see what the clearance is like with 3mm spacers at the back, this will make the offsets 4mm more aggressive than stock front and rear. Quite a bit of room at the back, this will make the rears et30.
I think you could squeeze in a 12, but fitting a 305 on would for me lose the advantage aesthetically without a 315 to go on. I think a stretch on 21 can look good but on a 20 it looks a little under wheeled stretched. At the front possibly another 3mm as well if you wanted to go a little wider there too. I am happy with the look at the front, I might have gone et27 or et26. But I will add 3mm to the back, to get the fatter look at the back
I guess I like the look of older wider 911's that emphasise the rear wheel drive configuration. Shame BMW only widened the front arches over stock 5's and not the back
If I was speccing now and running 275/305 I'd go 10x20 et 27, 11.5x20 et30 I'll confirm the rear clearance over the coming weekend
I agree with the lip been speaking to a few in the UK
