So, with the refreshed stock suspension and the upgraded brake system I started getting comfortable with the cornering and general handling balance of the car. One nice thing about long wheel base cars is that when they start to rotate, you have plenty of time to catch the back end before it comes around on you. So far the M3 has proven to be a lot of fun, though it tends to loose rear grip rather easily.... well... sometimes anyway. In fact, there were a few times that it let go when it should not have (based on corner speed and throttle angle). This got me thinking that it was probably time to replace the Rear Trailing Arm Bushings. Worn RTAB can cause unexpected changes in rear toe angle along with a mushy corner "set" on entry.
Once again I took advantage of UUC's "Buy Your Own Dam Present" sale and picked up a set of upgraded RTAB's.
Old Vs New:
To make the install a little easier I picked up an MIS RTAB tool:
Over all the install was not too terrible, I probably spent an average of 2.5 hours per side. The results are fantastic, no more uncertain corner set on turn in and a much more planted rear end. Still need to get a good alignment but I'm waiting till I replace the front control arms and install the TreeHouse front control arm bushings, hopefully in the next week or so.
