F/S: rear suspension links with spherical rod ends.
I have these same kits on my 93 coupe and have been very happy with the results. The rear end stays planted much better than when I had the stock aluminum links and poly bushings. I have had great results at both autocross and at the track.
I developed this kit with Gary from Hardbar and although there are other kits on the market we both feel this kit is superior in many ways. The bodies are knurled for easy grip and adjustment, even when on the car. The ends of the links are slotted like a collet and use Omega style clamps to lock the rod ends in place and eliminates the jam nuts, which can come loose. All you need to fully tighten the rod ends in place is a 1/4" 12 point socket. No need for 2 large wrenches to go in tight spaces like with jam nuts.
I have sold five kits so far and have gotten some great feedback from the buyers. I have more parts on order and will be able to ship in about a week.
The kits are as follows:
Red anodized aluminum turnbuckle links with steel bodied, Teflon lined spherical rod ends. All components are American made.
Nuts & bolts are all Grade 8 hardware.
All necessary spacers and washers are provided.
Trailing Arm Kit: $350 + $20 S&H
Camber Rod Kit: $225 + $10 S&H
If you have any questions, please don’t hesitate to ask. You can PM me through the forum or use my email below.
The easiest method of payment right now is PayPal, but I will discuss other methods if you prefer.

I recently purchased a full set of these, and although I have not had a chance to try them on track yet, I was pleased with the service, fit and instructions that came with the parts. Too many times, we are sold parts that either do not fit as they should, or come with scant or no instructions. Not the case here. I wish all venders came through like this one. I am anxious to try them on track, but becasue of medical problems, the earliest will be October. Meanwhile, kudos to Astock.

Finally got everyone off my back and got some time to install these.
Car feels great. It really freed up the rear suspension. The car actually dropped a bit due to less binding, yet I did not adjust the ride height at all. I scraped my exhaust for the first time after backing out of my steep driveway. (Car is lowered.) I can articulate the rear knuckle easily by hand when the car is on jackstands.
Going over speed bumps, I hear the front end squeak and bounch with the poly bushings. Rear end is quiet as a mouse and transmits less to the chassis.
Took it in the twisties, but improvements there are going to be impossible to quantify without lap times.
I don't know when my next track day is, but I'll have to repeat a track that I've been to recently and compare. May not be until a few months from now when it cools off.
.....
Everyone (without these installed) seems to think they'll ride very rough.
If anything, I found the opposite to be true. Now my car has never rode very smooth, but with the new Bilsteins and these installed, it's as good as ever. I had poly bushings on prior to this, and petrified stock rubber bushings on before that.
I'm not convinced how spherical rod ends can hurt ride quality, when you can easily articulate the suspension by hand, that means the suspension can react quickly to an uneven road surface. The stock pieces in their bound up state are very stiff and hard to move, and so they would transfer more energy directly to the frame, not allowing the suspension to soak it up.
I'll get pics this evening.

Yes, but with the stock C4's it's even worse since it's not a ball joint, but just a rubber bushed cylindrical hole, that really should just be used for 2d movements.
Here's a recent pic of my stock suspension, you can see the old stock rubber bushings binding up so much that they are being forced out.
Next time you have your wheels off, or it's up on a lift, check it out.
Poly bushings would actually make it worse since they take away compliance in the the off axis direction.

I just got back from Tom's place.
I picked up my order and got to see his car.
Nice
All top quality stuff. It's nice when an engineer works on this stuff.
