After getting more understeer than expected on my track car I was looking into geo alterations, I had heard good results from fitting ball joint extenders and had this planned when I wondered if MK1 TT hubs & wish bones would fit as these do the same thing as the BJ mount is lower on the TT hubs. Obviously this is a common upgrade on the MK4 Golf but I'm not sure if it's ever been done on a MK2 so I wan't sure if it would work even if it would fit. Mock up - TT wish bones fit the MK3 subframe perfectly and are the same length / track width as the VR6 ones I had been using I think the main reason this isn't a done mod is the fact that the TT hub mounts differently to the MK2, this is where these came in to help We had issues with the track rod ends as they're bigger on the TT than the MK3 so wouldn't fit snug. Solution - Drill taper out of hub & sleeve it Rose joint track rod end & allen head bolt Measure bump steer & spacer end from hub - Used alloy tube but wasn't ideal but all I could find at the time Then I found this laying around Drilled the threads out & shaved the top flat and it was the perfect size & tapered which was a bonus After it was all fitted this was the result - plenty of castor The only slight issue was the ARB mount, we made some basic brackets to see if it would work They caught the inner rim on full lock so as a quick fix we trimmed the corner off but it didn't work so we top mounted them and they seem fine now These seem to work ok but I do want to do them again as they look pretty poor I have 15" wheels and the BJ mount bolts are close but don't catch After driving the car at VAG Tuner Live at Donington this weekend it seems to have been a good improvement even with a pretty tame geo set up, late afternoon I altered the castor from the top to it's furthest point which gave even more grip. (Not sure what actual numbers this gives) If time would have allowed I would have then altered the camber to see the effects of this but before I knew it the session was over. I'm going to start where I left off regarding the geo and add more camber for the next track day and see how that works. The only other thing I really want to do before I use it again is fitting a TT quick rack as I find I have to turn more than I like to get it around corners, this mod might not be as straightforward as the above but I'm sure we can make it happen.
