Nothing to indicate orientation of offset.
Looking to install these soon but not sure how to orient these?
Since they require a set pin/screw, they need to be done correctly the first time.
Any experience or words of wisdom? BTW, I'm doing new control arms and tie rods at the same time.
EDIT: anything else that I should do while "I'm in there?"

I beleive the idea the idea is to orient the hole towards the outside end of the mount that holds the bushing (I think this is the bolt side, not sure). This kicks the outer ball joint forward and adds caster. I have a pair of these waiting to go in my 325 and that's my plan.

I just put these on today replacing worn stock offset M3 bushings. The hole goes toward the outside of the car. I am unaware of having to use some type of screw/pin retention with these bushings. They were just as hard to press in as stock ones. Should need no help staying there. I can let you know my impression after Summit Point next weekend.

Oh yeah...which car are you doing this on? If you are using the 95 offset bushing you need to make sure that you get the 95 control arm. If you mix and match M3 parts on the 325 you will get interesting results. When I took the stock arms with offset bushings off and put 95 M3 arms and offset bushings on my alignment changed a lot. So just be aware that you will have to string the car just to get it to an alignment shop. I put noticable wear into a set of tires in 15 miles before I strung the car. Just do not use the 96 and up arms with the offset bushings. They are different.

I have not heard any specific cases of the bushings rotating, but Turner actually recommends it. I believe it was in the Instructions someplace.
I drilled and tapped a hole in the casing and the bushing itself and threaded in a set screw. I believe I used a 1/4-20, so it was a relatively good size screw that would keep it from possibly rotating.

Boy thats news to me. Instructions...we don't need no instructions... Anyway I didn't receive any with mine. They were just loose in the box with the bag containing the front cross member reinforcement kit. Oh well. We will se what we can do.

...the set screw into the lollipop is a common thing to do....many racers I have spoken to do it. Just orient the new bushing to move the lca into giving you more caster( w/ the hole of bushing toward outside of car)........like mentioned earlier. It was common for powerflex brand poly bushings to move a bit( mine did)....so I did the set screw also.

This is very important, don't just throw offset bushings on a car just because everyone raves about them. Especially Dolemite since your sig indicates that you have a 99 M3. If you bought the correct control arms then don't install the offset bushings, you'll end up with too much caster (the front wheels will be too far forward). You should use 95 M3 control arms if you want to use offset bushings, not to mention that you didn't say what you have on top of the strut. A camber plate or a stock strut bearing?
If it's stock stick to stock parts (ie no offset bushing).

.....just curious Carlos.........
are you saying NOT to use offset lca bushings on 96 and later control arms? Do you mean '95 e 36 M3 offset bushings specifically?
I run Powerflex offset bushings on both my 90 325 i and a 99 Z3 coupe.....I have never heard this caveat?!..does it only apply to e 36 M3's?
I realize too much caster is a bad thing and one should never just throw parts on a car but what are the issues here specifically?.....

The wheels being pushed too far forward, they're no longer centered on the wheel well opening. If you run 18s, which a lot of people do now then the tire may contact the bumper cover. Other than that I'm not aware of other issues, perhaps the steering gets more difficult that part I'm guessing at.
Z3 coupes are a funny animal, at least the M Coupe has different caster than E36 M3s from what I can tell. If you're using them and they work for you then leave them alone. Also if I were running adjustable camber/caster plates I'd have no real issues combining the two as you can tweak the suspension to suit your needs with adjustable plates.

Thanks for the info guys. I should have been more clear on the application.
These are for a 95 325is project with new stock 325 arms going in it. The car is also getting GC coil over kit:

I plan on running 15x7 wheel/tires.
There were no instructions just printed on my receipt that the set screws were required. I actually called them back thinking that they should have been in the box but weren't. Not a big deal just want to get it set right the first time.
