at a guess, being that these are Grp A RL7's, what would you 'Predict' the offset of these wheels to be by the way they seem to sit in the arches?

they are 8x18's.

trying to work out the offsets by measuring the wheels, but they seem to measure up as et25, but from what i recal of escort cossie wheels (being that they are et25) they sit out alot further than this.

im hoping they are et33.

Cheers
