All of the factory subframe mounting pieces have been cut out of the chassis. I started to cut out the mounts from the MK5 to use in the MK4 but the metal in that cassis is harder and broke all of the spot weld cutters that I had. I'll just make new ones all together.
Here is the chassis with all of these piece removed.
Mk4 balljoints vs. mk5 balljoints. Turns out, they just drop right in to the MK4 knuckles. oddly, I checked it out and the MK5 axles go right in to the splines of the MK5 knuckles too, meaning the lighter/stronger tube axles have potential in the MK4 chassis! It may be possible to do a complete MK5 knuckle swap. Maybe Passat aluminum knuckles and TTrs aluminum control arms will be future upgrades for this car.
Here is the aluminum subframe all lined up. I'll be welding in new mounts tomorrow.
