That would be awesome Hans,I thought it was awesome that you guys started carrying poly front subframe bushings.
I'm glad when shops keep developing parts for the 3s

Wonder if the ones with the additional caster would be beneficial? Patterson, thoughts?

NO NO NO NO NO NO NO NO NO!

OK, let me explain. Yes the caster is good, but how they did it is wrong for our suspension. Basically they copied the 1995 BMW M3 design. Since we don't use a ball joint as our front control arm mount, then moving the rear mount binds up the control arm and prevents it from moving correctly. The rear mount MUST be on the same plane and inline with the front bushing when you have a single axis bushing. The soft stock bushing might take it, but it's going to wear out faster and hurt performance. OR, you could get a little ghetto and oval the forward mounting holes and give the bracket a little bend......

Now, if you replaced the front bushing with a monoball or spherical joint, then yes you can use that piece, but by then the rear mount is monoball anyways.

Good info.

It would be great to see the polys available at GZP but in the mean time I ordered a set from Buck Waller. Yes he's still selling them.

Slightly off your original topic, but how are you getting the two front press-in bushings (website link?)?

That's the only thing I couldn't locate for mine & just figured I'd have to have them custom made or try to find two that would work from another application.

In for a response...

+1 on the caster change ones, I really didn't see how that would possibly work.

The rear larger ones are pricey, I bought mine strait from australia from SuperPro Superflex is just a distributor for them. I paid about $120-130 shipped for the set. I think superflex was closer to $150 or more if I remember.

Im sure if enough were interested we could probably get a discount for quanity too.
