Update:
The car attended its first event this past weekend and worked great. It was a ride along program where we give a two lap ride in the car around the autocross course. The course is pretty brutal, it is tight and has elevation change in it but the car survived with minimum issues doing over 300 laps in two days. But before we post pictures let me update this thread with the last few things we did before tracking the car. So stay tuned!
We rolled the rear fenders to prevent tearing the tire. With the car height the tire would easy cut when the suspension loaded.
We also replaced the rear control arms and panhard bar with Roto-joint items to allow more articulation.

Even it hadn't rained Saturday morning the lines might not have been so crazy in the afternoon.
Sorry you didn't get a ride!

This car felt very good in the passenger seat. Flat and the brakes work.
My son AX's a 2nd gen and was also impressed with it. Actually, I think we spoke with Ramey about where you guys run. My son is a regular with the Susquehanna region and invited you over (the El Camino is familiar).
As a matter of fact, your in luck!...this Sunday will be at the Giant Center at Hershey Park.
Hope to see you there!
Good job UMI

I have them in my rear LCA's. When greased and tightened they make no noise. I just recently had to regrease and tighten them up because they started to 'click' at lower speeds on decent sized bumps.

So I started a thread a few minutes ago but since UMI is here maybe you can help me. I'm on a budget trying to do a basic drop on my 2000 SS. I want coils and LCA's. I already have one of your adj. Panhard bars. My question is:
For the LCA's I am on the fence about doing adj. LCA's and mounting them to the stock location on the frame or should I get the LCA relocation brackets and keep the stock LCA's for now. Are the brackets really that necessary if the LCA's are adjustable?
What do you think UMI?

It really depends on your plans with the car. If the rubber is worn and causing wheel hop or other issues to the performance, I would recommend a new LCA first. The brackets change the instant center to allow for better forward traction. Or in your application, it brings the tail end of the LCA back to the angle GM intended for after lowering your vehicle. Basically, it fixes the geometry you compromised when lowering your car.
Hope that makes sense!

Finally got a few pictures available to share, there will be more coming.
The car got its stickers and competed in its first autox event. Over 2 days we did over 400 laps at the Carlisle autox track giving customer rides and running the Friday night shoot out. The car did great, the track was higher speed and fairly brutal. The Hawk DTC pads worked awesome and we chewed through a set of front rotors in just two days.
Rear window stickers.

DTC pads throwing a few sparks.

I've been having better luck with the moog brand hubs over the timkens. The moog are available at advance auto and have a 3 year warranty also. Stock ones are good if they aren't already loose, and they are getting hard to find. There have been a few solutions over on FFRAX, one uses a 3rd gen type spindle and bearings, one is an adapter that bolts on to the spindle so you can use a SKF c5/c6 race hub, and there is another company called Hoosier Performance Engineering that was making some billet machined hubs that look like stock but use giant tapered bearings. The adapter and the new Hoosier hubs allow you to keep ABS, the third gen set up does not. Sadly, none of these options are cheap. Luckily, changing hubs is a quick job.
