I am looking to replace the k-member in my 97 GT Convertible. I want to do it now because I have to drop the stock k-member to change the headers. So I might as well put a tubular k-member back in. Since I am not ready to do the rest of the suspension I would like to keep the stock control arms and springs. Money is tight so I am trying to do this as cheap as possible. I am leaning towards the QA1 because it has replacemble motor mounts. The car has a 4.6 now but I have a big block in the garage that I might want to use later. The QA1 will let you use the stock control arms but requires coil over springs. To avoid haveing to use coilovers, can I purchase the upper spring purches for a UPR kember and use them with the QA1? Any idea if this would work?
