I'm new to this board,but know these cars reasonably well from prev. e-28 M5, e-34 exp. I have a couple of questions before I get started.

SLS units leak - would prefer to keep the car as built w/o spending $900 ea to replace them - any suggestions.

Suspension rebuild... Usually, I replace the UCA bushing with 7 series bushings - Is this req. here or are the M5 bushings an upgrade from the std. e34?

On the last e-34 I owned I relaced stock sway bars with Nuremburgring bars to cut some of the roll when cornering... Is this worthwhile in an M5 or is the stock bar thicker than a std. e-34.

Does a Conforti chip make a perceptable diff.?
