Delrin tm I hope your not serious.... That's the material they use for headlight bushings
In c4's & birds I have rebuilt 4 headlights that material... Turns into Crystal powder
Now just imagine how devastating that would be on your suspension

I have all the Banski pieces in my C4 and it greatly helped ride and handling. I was also able to align the rear end much much faster with the Banski kit as adjustability was greatly improved over stock. I used it with all OEM rubber bushings up front but I have since swapped out the front lower bushings for del-a-lum ones, and I made my own upper control arms using heim joints.

Thanks! I wanted to make something similar to the SPC adjustable arms but at a fraction of the cost. The SPC arms are around $250 each and I have about $150 TOTAL in material cost in mine. The 4 heavy duty high mislignment joints were $125 for 4. The steel and clevises make up the rest of the cost, and the aluminum was generously donated by Kettering University!

Unfortunately, all the machining was done on CNC machines at school last year (just now getting around to putting them on ). I have the CNC program saved, but no access to CNC machines anymore. If I could make more I would.

Not to get too far off topic, I posted this to help express how well heim joints work as suspension members. Low friction and near zero deflection. Banski's rear end parts are the way to go. If you cant buy all of the parts at once, start with one kit and dont spend money on upgrading the rest, just wait until you can get all the kits.

Very nice looking arms, keep the CNC program.

OK I admit, those are not mine... I do not own a TIG welder and had those done by a guy at my work. While I do know how to TIG weld, mine would not have looked as nice.

The school used to be GMI (General Motors Institute) but is now run by the grandson Charles Kettering III.

The ball joint plates are just 1/4" steel. Unfortunately I do not have access to the proper machines to reproduce the arms. If I ever can I will be sure to let you guys know. I have not had them on track yet, Im still building the rest of the car.
