It started out a bit difficult in the rear as we jimmied the Whiteline rear subframe lockout bolts into place. The procedure that proved to be great for me goes as follows:
1. Remove Tires and Rotors (you don't have to take off the rotors but I am getting mine turned so the extra room was nice)
2. Clean out the holes with air and/or pipe cleaner
3. Insert Whiteline bolts into subframe holes and tighten (mine went right into the holes and threaded without issue)
4. Loosen all 4 subframe bushing bolts
5.Tighten the Whiteline bolts slowly with a breaker bar for ease (I didn't need the crowbar, I tried it but it seems like you risk hurting your brake lines and are unable to actually shimmy the subframe over the bolts)
NOTE: there is speculation that the bolts should be exposed and not screwed in all the way to allow for the subframe to move up and down. THAT IS COMPLETELY INCORRECT. The bolts should be tightly installed at 66 ft lbs with the head of the bolt flush with the outer subframe casing. It is a tight fit as the tolerances are extremely small, but you should be able to get it in there if you have a clean hole ;)
