that was a while ago i fitted them but i am 99.9% sure its ET35, they came off a sierra originally.

Like i say yours wont be quite that extreme if you have drums, but mine is also very low.

I took the handbrake off and the car wouldnt move cos the arches were sat on the tyres.

Where they will rub i can almost guarantee, is the right hand side of that picture. Thats the passenger side arch, and the rear side of the arch curves in past the sidewall. I carefully ground mine out and they dont rub at all now. But im not a fan of grinding arches personally
