Hey all. Ive had the new Eibach Ground Controls on the car for a bit now, running the stock tops. It's time to get some camber plates, but I need advice on what to get as there are several options varying in price. Theres the cheapys on ebay that would work just fine if I knew theyd work right, and Techno Toy, which is a hair expensive, which I dont mind if its what I need.

I have had a problem with the steering on the car since I put the GCs on. The steering doesnt really return to the zero center position if you know what I mean. It kind of wonder steers. Ive pretty much been rebuilding the front end hoping that solves the problem. I put new control arm ball joints and a Moog idler arm in and it made a huge difference in tightening it up, but the wonder steer remains. Im installing new inner and outer tie rods as we speak. Pitman arm looks like the original owner replaced it (although its not in my binder of 34 years of receipts I got from him). It looks shiny with a like new boot.

My last thought is that the stock tops arent allowing the GC tops and springs to rotate freely and binds them up while turning. If I remember right my REspeed coilovers had thrust bearings and never gave me this problem on my old 79. So I need camber plates that will allow the struts to turn freely.

Thoughts? Suggestions? Any would be appreciated.

 

Im basically running this kit with Eibach rear GC non sleeved springs.

The fronts are welded on, 200 lbs 8 inch. Rears are just like stock, but shorter by a few inches to lower the car with dead coils and Id guess 175 pounds.

 

the GC has a thrust bearing too.

this is usually a really fine tuning race car thing, but springs actually twist as they compress, and so either the top or the bottom needs to rotate.

apexi sells a teflon looking ring, and hypercoil actually uses a bearing, again this is like turd polishing race car stuff, and you shouldn't need it on a street car Hyperco / ICP Hydraulic Spring Perches

 

My GCs came with a solid spring top. No bearing recess. I just dropped $263 on T3 camber plates and tops with bearings that basically look like end play thrust bearings and plates. I want smooth as silk steering response. As smooth as the old style rack will give me that is... i wonder if i need roll center spacers... i basically gave the car a 2" drop.
