Been a bit too busy to post updates, but here's the latest:

A few weeks back, Miles (mkodama) and I tackled the M3 front suspension upgrade. My front brake pads were getting thin, so I figured it was as good a time as any.

Here's what we started with (stock 325i calipers, control arms, tie rods, powerflex FCABs):

Undo the caliper, pop all of the ball joints out and release the compression collar bolt to free the king pin:

Pop the inner ball joint and remove the FCAB bolts to free the control arm:

And this is what we're left with:

Same thing on the other side:

Took the boot off the tie rod and started unscrewing it from the rack:

I used a very large adjustable wrench to release the tie rods from the rack. After 54k miles, the ball joints are still in very good shape:

M3 tie rod end attached:

Same for the other side, along with the shiny new M3 control arm:

With those in place, the new M3 king pin was installed:

New M3 reinforcement plate, with that wonderful puck for the center jacking point:

Brake dust shield (already modified for BBK) installed along with the small inner dust shield:

New M3 wheel bearing (note that it accepts 2 set screws instead of 1 and that it has 2 dowel pins). Torqued down to 200+ ft-lbs (oiled).

Finally, the dust cap is installed with a little sealant:

Massive 365mm Alcon/Stasis brake rotor also fitted:

Those wheel bearings were tight fit on the spindle, so I got them nice and hot to ease installation. Didn't help tremendously, but a hammer and large socket took care of the rest.

Other side done:

And that's all for now. Pics with the new calipers and wheels after I get an alignment.
