For the guys w/ no bottoming problems, what strut brand/models are you running? Stock struts have a lot of shock travel compared to some of the race valved struts. Which might be the issue, as the shop that I had the dicussion with is commonly using 28 series Konis on PCA Club Race cars, in the 700-800 lb/in range.
So - anyone know?

I'm using the plates show in the link from944CS. 250 lb springs on the Ground Control stuts with Koni Sport inserts. Lowered as far as it will go without rubbing. Just put in the Rennbay track ball joints and Weltmiester control arm bushings. Feels great now.

I have had a set of the TRG plates on a PCA Club Race 951 for about 8 yrs w/o issue. The factory mounts, RE plates, Kelly Moss plates, etc. all take the load right on the bearing.
The only benefit I can see of having the bearing in a rotating spring hat, is that the coil spring will not bind or slip on the top hat when turning. Anyone with a rigid mounted top hat, has heard the springs pop on occasion when making tight turns in the paddock, or backing out of the driveway (as the bottom perch rotates with the strut and the top perch is stationary with the camber plate.

Instead, the weight of the car is supported by a completely separate articulating needle bearing, which is also manufactured for Ground Control in the USA.

I am aware of GC's marketing claim. But the reality is that having the load sit on the spherical bearing is not a chronic problem, as all other camber plates do w/o significant issue.

one benefit of the GC design, which I'm surprised they don't mention, is the reduction in hysteresis of the suspension with those needle bearings. Gives a more consistent wheel rate.
In the sports car world at the club level this is often never even considered but once you go to open wheel cars or up past club level this is a major consideration
