It would make lots of sense to try them with TT ball joints at least.
I wonder why Joe didn't, since ball joints use to be quite cheap esp
compared to those aluminium control arms.
I think he had superpro ball joints that fit the mk5-7 GTIs. Unfortunately, people have also claimed that there isn't enough clearance between the superpro ball joints and the rotors in the performance pack or golf r to make them work.
Somewhere on vortex, someone claimed that mkii TT ball joints fit the OEM mk5/6 GTI lower control arms.
The mkiii TT has unique lower control arms, but same ball joints as mkii TT.
We also know the mkiii TT lca fit the subframe and chassis of the mk7 GTI.
So if all of these statements are accurate, then both the superpro ball joints and mkii TT ball joints fit the mk5/6 GTI lower control arms, but only the mkii TT ball joints fit the mkiii TT lower control arms (because Joe said they didn't work the superpro ball joints).
I guess the question becomes, how can the mkii TT ball joints fit both the mk5/6 GTI and mkiii TT lower control arms, but the superpro ball joints only fit the mk5/6 GTI control arms.
Bottom line: considering the demand for camber adjustment on the mk7 GTI and R, and the fact that people are willing to pay ~$800 for superpro lower control arms, it might be worthwhile to see if the mkii TT ball joints will fit the mk7 GTI w/PP and R lower control arms for less than $300.
