Looking to convert my struts to coilovers with a rally design kit. However, I've noticed that the ta coilovers use a cut down strut body that houses a shorter damper. Can you buy these separately or are there off the shelf options? I don't want to run standard length dampers because I don't want them bottoming out. Any help would be great

I believe that GAZ Shocks coilovers are the same idea. So might be worth speaking to them to get a set of shocks made up.

They're not an insert I don't think. They weld their own twin tube body in with the original polo steering arm attached to it.
