tryan,
I could push a little harder in getting a parts replacement warranty on the coil but they would more than likely just replace one coil. This, in my book anyway, equates to changing only half of the spark plugs or changing only half the oil. I hope to get another 125K miles out of the Benzo so new coils are prudent at this juncture.
All,
After a bit of research over lunch regarding coil spring availability, PGAuto sells new rear assemblies for $100 each.. Nice price but I don't need an entire assembly, just the coil. Food for thought nonetheless.
Eibach and H&R offer springs for the M-class and are available through Tire Rack. Moderately priced also...
Eibachs = $201
H&R = $154
Eibachs make decent springs but after an unpleasant experience with their product causing severe understeer and terrible ride profile on my SVT Lightning, no thanks.
According to H&R's website and phone tech, their product will lower an M approximately 1.25" in the rear. I can live with that.
They mentioned/recommended adjusting the front torsion bar to compesate for the rear drop. We'll see how it looks and, more importantly, handles once the springs settle.
