I ordered and recieved a set of bearing/solid bushings for the front and rear A-arms. These replace the main pivot bushing on all four a-arms and the kinematic arm bushing on the rear a-arms. I can easily press the bushing for the kinematic arm out, but I am at a loss how to easily remove the inner pivot bushings. They seem to be press formed into the arm and my attempt to remove them from a spare arm has so far resulted in a lot of damage to the arm. Anyone have any experience with this?

Ed, the inner bearing (the part that attaches to the subframe) is pretty complicated. The bushing in the middle of the control arm is pretty straight forward.

You can call Bob at Stable Energies. He does this work quite frequently. When Jon Groom installed mine, he sent the arms to a machine shop.

Where did you get the bearings and bushings? Do you have the part #s? Thanks

you get get them HERE

Ok, I played around in the shop a bit today. If I machine the ends off I can press them all out pretty easily. I was playing around on an old set of solid arms. I am running split arms, front and rear and it looks like the cup car rear arms used sperical bearings here and all I need to do is order (4) inner control rod ends and they come empty and ready for the new bearings. Suggestion to others out there... price out the Cup parts before jumping on the ERP parts, they MAY be cheaper.

did you take pics?

Car is all still apart. I am getting my Motons overhaulled, installing a new clutch adn flywheel, new engine mounts, new roll cage (done), new battery, cup car rear wing and a bunch of other little tidbits. Shoudl be killer when it is done.

Ed can you run GTC3 with Motons in PCA?

Ed Newman

Its a C2 not a cup car so I run in B as prepared. I believe you are correct that you cannot run Motons in GTC.

Ed, what year C2 is your car?

The original bushing (rubber) on a one piece and two piece arms is pressed in can can be pulled out but, takes a little work. The OEM bushing is pressed from either side so it has to be pulled on one side first and it will destroy the bushing in the process. You have to use a drift and bend the outside retaining lip up so you can get under it with a split bearing puller then press it out. The one side remaining can then be easily pushed out using a large socket. I will try to take one apart in the next few days and post the pics for future reference. You shouldn't have to machine anything if you do how I've explained.

As far as pricing, the last time I looked at getting some inner bearings from Porsche Motorsport they were a bit over $350 each. The ERP bearing is snap ringed in and easy/inexpensive to replace when it wears out as well.

My car is a 2003. I am going to try and put the ERP bearnigs in the motorsports ends which I would believe to be the same as the street ends (all from 2 pc arms) just less the pressed in bushings. If so, it should work out well.

whoa, mr.ERP himself. thx for chiming in and i look forward to seeing those pics.

In the pictures below (hope they all made it) I show how I take out the OEM rubber from a one piece arm (exact same procedure for Cup style two piece end). I also show a simple tool I made to help extract the bushing. It's made from a small piece of tubing and two off the shelf bolts. This a tool that can easily be constructed in the average home garage in a short amount of time. The last picture shows a factory GT3 RS bearing on the left and to the right of it is a GT3 Cup/street car piece that originally had rubber like the one piece are which I removed and replaced with an ERP bearing cartridge ... way cheaper than buying Porsche Motorsport parts and serviceable as well. I hope this helps out.

Ok, so it looks like what I am missing is the tool in the third picture... what is it and where do I get it?
