i think my mate had similar size/lowered etcand it was ok, slight scrappin but roll arches and was fine!said it handled not bad too on them
Hi Rob, I think those tyres will probably rub. The other thing is that the rolling radius will be out by ~6.5% so your speedo will overread by that much too. As craggsy says, 205/40/17 are the correct size for 17s on the mk3. Check here.
Will more than likely rub yes. I have 17's on mine with 205/40's with a 35-40mm drop and the rears catch when weight is in the back and going over speed bumps sometimes. So a 50mm drop and 225/40 will probably catch a lot more unless you roll the arches. As garfayliu pointed out you would want to be going down 205/40 to keep the rolling radius as close to normal as possible also.
it all depends how wide your alloys are.i have 8x17's,and i will be installing a 40mm lowering kit,and there will still be clearance.forgot to mention i have fitted 205/ 40 profile tyres for that stretched look.really good look,but have to watch out for potholes!!!
