Mine is -60 on the back, around -70 on the front.
Yeah fella, sikaflex the buggers on. The arches are just held on with cheap crap 10mm plastic nuts, half the time they snap the bolts off when undoing them anyway!
Have a gander at mine on Sunday, you will see what I mean! With the spacers on the front to clear the stupid f*cking brakes it means I am ET39 on the front and you can see the issues it will create without putting the steering on.

Front arch liners must be binned, so a detailed bay will soon look like sh*t.
