[QUOTE=tuna]yeah plus they are not machined correctly to contact the ridging of the belts also (resulting in lots of belt dust)

ie, off centre and the ribs were too tall.[/QUOTE]

GFB have different sets for the same model cars i.e. there are 2 different sets for an 06/07 sti, to do with minor changes made from beginning to end of production of vehicle. the shop i got mine from knew about this, and was happy to exchange the set if it was incorrect. Ebay and the like wont tell you about this and that is why you could end up with wrong offsets. mine were machined beatifully and perfectly round and the belt fit perfect also, no slip no dust.

Ok simple question, heard a few things about this overdrive stuff, rough price if anyone knows for a gc8 and best place to get them. No real hurry, just something to look forward to in the future as the next small mod, once mechanicals are sorted after that prang.

Ty in advance.
