I was just looking at these Rogue Engineering Front Control Arm Bushings, anybody have experience with these?

Looks like a nice part. Better than the delrin stuff thats out there.
Or go one step further.

Stay OEM if you are street only. This just messes with noise and ride quality for a street car. You will not likely limit a good condition OEM CA bushing under normal or even spirited street use.

These nearly solid-mount bushings are going to ruin your street ride comfort. If you desire an upgrade, I would suggest the "Street Performance" version of the Powerflex LCA bushings. You can go with the offset version to get more caster. You can order these through me, as I'm a retailer for BimmerWorld. Let me know if I can help. (email Anthony@DriveFasterNow.com)

If you don't want to have to press or cut out your old bushings, you can get them already in the new lollipops:

I have heard powerflex LCAs had some issues at one point in time, plenty of posts on the e46 forums of people having them disintegrate. But looking at the rogue website for the e30/e36 they have street versions which have a metal surround with a polyurethane center. Why would that be considerably worse than Powerflex or AKG or any other polyurethane bushing, the portion that the control arm goes through is more or less the same. Just the surround is metal, which seems like a safer bet to me as far as potential failure goes.
The rogue bushings have an exchangeable inner portion anyways, since you can order replacement inserts on their own...

Suspension: Bilstein Sports, GC Coilover conversion, IE Subframe Bushings, IE RTABs, M roadster sways, M roadster front control arms, M roadster Front calipers/hubs.
Engine/Driveline: M54B30 intake Manifold, Dinan CAI, ZHP Cams, Headers, Underdrive pulleys, Conforti Software, 3.46 diff.
The metal in the bushing serves no purpose other than to reduce the amount of compliance in the bushing. I would not even recommend the Track Performance PowerFlex bushings for street use. I just put them in my Z3 and quickly realized that they were too much.
LCA bushings are a large contributor (or isolator) to impact harshness. Allowing wheel regression (rearward movement) upon impact significantly reduces the vertical acceleration and, as a result, harshness. Of course, it's a trade-off to steering response. I would recommend the Street Performance rates for a street-driven car, though. It's a significant upgrade to steering/handling/braking response, but won't be as abusive to you if you're driving on anything other than glass-smooth road.

Powerflex have 2 different materials in their bushing range, purple for street use and black (stiffer again) for track use.

There is only one thing more pleasurable than working on a Z3, that's driving it top down on a fine day.
Bubba, may also help if you explain your intended use for the car. Daily driver, weekend canyon carver or dedicated track rats all have very different suspension needs

Another option is to use the e36 M3 control arm bushing. M3 bushings are firmer than standard bushing (solid rubber vs. webbed design), but not as stiff as urethane. These bushings can be pressed in easily with a shop press.
I have run both power flex and M3 control arm bushings in e36/e46's and z3 cars. Both are an upgrade over standard. Ride quality ranking: stock > M3 > urethane > delrin > spherical bearing. Spherical bearing would be the most performance oriented by design, but have the least about of deflection over bumps. If you use urethane, grease them well...
