Bolt on hubcentric spacers are preferred over slip ons with longer studs.

As for diff failures due to offset or tyre pressures, I've never seen one, this is the first I've heard of it.

I have heard one "story" of someone manually adjusting the cdiff as tight as it would go to make it skip around like a locker, the idiot was on dry bitumen, it eventually screwed something in the drivetrain.

I would say people manually adjusting the cdiff on a high grip surface is the culprit for drivetrain problems not offset.

I have Garageline 15mm front and 20mm rear with the base STi wheels. I haven't had any problems at all. I'm considering going to 20mm in the front, but I don't want a lot of poke.

20mm shouldn't really poke any in the front, I'm running effecively 8.5 +30 up front (+50 with a 20mm spacer) and it doesn't stick out at all, no rubbing or anything with swift springs to lower it either.

I've been running hub-centric 20mm spacers for over 40,000 miles and no issues. I also have RCE Yellow's and have zero rubbing.

If you go 15, you'll end up wishing you went 20.

Yes, this.
There are some people on here seemingly confused.
