Alpina B7 Turbo/1 – some work on the underside

The B7 has had some improvements in the last few years. Not that anything was bad, but just because I could. Here is an overview of some of the things that have been done. First the car on the lift:

Pitman arms rear, new diff mount and revised diff came first. At the same time this was the perfect opportunity to replace the anti roll bar (sway bar) mounting bushes with the versions from Powerflex.

Of course only new parts from Lemförder:
Alpina B7 Turbo - suspension - 7
Alpina B7 Turbo - suspension - 12
Alpina B7 Turbo - suspension - 11
Alpina B7 Turbo - suspension - 13
For the LSD I used Castrol Syntrax 75W-140:
Alpina B7 Turbo - MyE28.com - LSD + oil - 33
The diff itself received new seals at the input and output shafts. A new temperature sensor was installed as well:

On the front I changed and upgraded the Upper Control Arms (UCA), the Lower Control Arms (LCA) and the drop links. Of course again all from Lemförder. The LCA is actually the aluminium version from the E34; same size and fit, only a little bit lighter and stronger:

Looking back, I could have gone for E31 control arms which have spherical bushes as well, but that will be for a next time!
