So I was wondering if anyone makes delrin or solid front control arm bushings like this one, http://www.bimmerzone.com/images/Powerflex4601.jpg
All the ones I see are a 1 piece design and I feel it might be resisting against the arm moving. The BMWs I work on have similar front suspension design to the fc, but I notice their fornt control arm bushing design seems to allow for better movement. I do not want to buy the awr needle bearing ones. I feel a properly designed delrin bushing should do just fine since the movement on that arm is supposed to just move up and down, unlike the rear suspension

i agree, i tried a set of arms with the regular poly bushings and i didn't like that they didn't move!

I guess there isn't enough of a market for someone to make parts for our old cars and make enough to keep them satisfied.

If you remove some of the barbs on the rear mount of the FC arm, the delrin bushings work pretty well. The large rear bushing is the issue.

The poly bushings don't work very well at all.

Which delrin ones did you go with? I saw one on ebay for $50.

I have MMR ones, and a couple sets of drop engineering ones from when they were having a closeout. MMR is on the car now.

I think these are the only ones that I know of:

FC Front Lower Control Arm Bushing Kit ? Delrin |

The rest are all not available anymore.

There are the ones on EBay, and Mariah Motorsports still has them on their website as well.

Mazdatrix also sells the Mazdaspeed ones.

I ended up buying some 50 dollar make you holla special of eBay. I'll look into grinding off the barbs for smoother movement.
I figured it's so cheap it would save a ton of time on material and fabrication to make my own. I'm hoping worst case, if it's too tight, I can always machine or modify these

You could grind the barbs down, or use a brake hone on the bushing to open it up until it is smooth, then pack it with grease.

I picked up a set of delrin ones from ebay for $50. I will install them today and let you guys know how they are. I figured worst casei would have my buddy modify it if it doesn't fit

So I installed my $50 DROP brand delrin bushings purchased from Ebay. Well , it wasn't the white delrin but the black material. I forgot the formal name, but pretty much like delrin.

I grinded down the barbs like you did and I got a slightly smoother movement, thanks for the tip!

Also for the 2 piece bushing in the front, I noticed if I torqued the bolt down it would make my arm movement a little too stiff. I ended up using a lock nut and putting only a little torque on it, then I double nutted it so my lock nut wont back out. Seems like bang for buck front control arm bushing solution. I think I rather take a bunch of time custom fabricating a control arm over spending the money on the awr needle bearing arm.
