Default Adapter spacer on rear drum assembly safe? And different offset, but same tire OK?

I have an '08 Impreza Base model, and the rear brakes are a drum assembly(God damn Subaru. =/)

1. I was thinking about running a 20mm adapter spacer with studs from Kics. And I was wondering if the rear hub will be able to run the adapters safely? I chose 20mm, as I researched I wouldn't need to trim my stock studs.


2. The difference for the front and rear offset would be 15mm.
38 in front
23 in rear
Same tire, same wheel height and length.
My diff won't be messed up correct by running two different offsets?

No, your diffs won't be bothered by different wheel offsets.

I'm sure someone will jump in and tell you this idea is stupid and your wheel bearings will explode into flames in short order and blah blah blah, but assuming the spacers are bolted on properly there shouldn't be any safety concerns with the Kics spacers.

Thanks, just what I wanted to hear. I am aware of my wheel bearings exploding as soon as I place them on

I just need someone to answer the damn spacer on rear drum question. God damnit.

Your car is going to handle awful. Understeer galore.

Conversion spacers are absolutely in no way an acceptable way to convert lug patterns. The idea needs to be stricken from your mind. The only viable way is to swap hubs.

Also, is there any reason your are only wanting to convert the rear?

My only question is why? Why would you only want to run the spacers in the rear?

That said, I don't see why it would be any more harmful/bad to run spacers on a drum over a disc setup. I guess you'll just have to try and find out.

Where did he say he was converting bolt patterns? As far as I can tell Kics just sells bolt-on spacers with the same lug pattern.

I'm running an adapter spacer in the rear 20mm, and a nonadapter 5mm in the front. The difference would be 15. I'm not changing any bolt pattern....

then you aren't running "adapter spacers" if you aren't changing the bolt pattern.

youll be fine with drums as long as the spacer sits flush on the mounting surface of the drum itself.
