January 3, 2011 - Here's the view from the rear.
The tight packaging for the mufflers is pretty evident - in fact, that black mark on the right muffler is the insulation from the fuel level wire before I put some heat shielding on it! The new frame members running forward from the trailing arm mounts aren't very visible, but the arms of the lift are lifting from there.
The inspection did reveal a few things. There are a few wires that need to be wrapped up mostly for appearances sake. That fuel level sender wire is still awfully close. The fuel line and main power line also run pretty close to the exhaust (hard to avoid given the giant X!) and really should have some extra heat shielding just in case. But it's pretty good overall.
One thing did come to my attention. The pinion angle seemed a bit off, with the nose of the diff higher than I think it should be. The alignment shop set it, but either the adjustment shifted because the lock nuts weren't tight - they weren't - or they have a different idea of what it should be. The angles of this setup could very well be the reason I'm getting a bit of vibration in the car. Not a shaking, more of a deep rumble that could be the stiff motor mounts, exhaust noise or drivetrain vibration. So I dropped the nose down a bit and we'll see how it works on the drive home. Not tonight, though - a surprise snowstorm marooned the car at work and I went home in a stock 1992 Miata. Regular readers will remember I did almost exactly the same thing two years ago in the Camaro!
