This is quite perplexing. In a solid bar, I cannot see why a bushing stop was not welded in as the factory unit. Of course, if the anti roll bar was 4130 tube (as tended to be ARB's of works race cars as such bars are very much lighter), welding could produce weak spots and a collar, such as the below pictures of a titanium collar weighing 60 grams, might be used. But, then, again, the question is one of producing a collar with an appropriate securing mechanism!

Robert:

The collars that are supplied with the TRG solid bar are very similar to the pictures you posted except they do not have what appears in your photos to be a set screw. Additionally, the supplied collars are not a perfect fit when bolted tightly to the bar. Lastly, and as mentioned before, the collars are butted against the aluminum front sub frame to limit lateral movement; however, a relatively small percentage of the collars actually contact the sub frame. If a proper “stop” could be welded onto the bar so that they would contact the rubber/plastic bushings, I think the bars would be great. As Steve W. mentioned in his post, very similarly sized OEM bars are available from Porsche Motorsport if you know what you want.

Thank you Hank. It would appear that there are two viable solutions -- weld a stop in or buy factory bars (i.e., the type of stop I have pictured is not a solution in this instance due to cost considerations). The former solution would be less expensive and I would imagine that TRG could do this with minimal difficulty.

George, remember that the TRG RSR setup is simply custom valved Bilstein's with Eibach springs. TRG didn't really manufacture them.

Get the factory bars (RS or Supercup). That way, there won't be any compromise. And most of all, you'll be happy.

Matt,

Couldn't agree with more. That's exactly where I'm headed. BTW, my setup came with Faulkner springs.
