Hello gruppe,
I just got our 1999 528iT with sport package back from an alignment
because it is chewing up the inside edges of the back tires. The
alignment showed the left rear wheel to have -1.8 degrees of camber and
the right rear to have -1.4 degrees. Spec is -1.5 to -2.2 with a full
tank (the car only had half during the alignment). The weird part of
this is that the right rear with less camber is wearing worse than the
left. Both wheels are right in the middle of the range for toe. Is
this just life with a sport package E39? I would guess that the BFG's
on the car will show wires on the inside edge in less than 20k miles of
rear tire use. After 10 k, the inside edges are mostly bald and the
balance of the tire (60k tread life rating) looks near new. This is my
wife's grocery getter so mostly there's no fun of any kind (track,
autocross, or such), heck it only gets a decent off ramp run once in a
while. Car has 120k miles if it matters, drives great and steady as a
rock. Any ideas what to check other than get off the couch and rotate
the tires more often?
Regards,
Paul Craven

Dynamic alignment can vary from the static settings. I would check all the
bushings for wear or slop. Your alignment is not sufficiently off to cause
such poor wear.
A belt separation in the tire will cause accelerated tread wear. Perhaps
your tire is failing.
If you want better tire wear and fuel economy, set the toe and camber closer
to zero. This may allow the tail to get a little loose on severe evasive
maneuvers so be careful.

Still need MAF sensor for any E36 //M3, 323i, 328i,
or E39 528i.
Turns out the one I tracked down last week, has a broken element too,
the opposite one from the one that's bad on my original one. Too bad
these can't be transplanted :-(

'97 //M3, currently only 21mph highway, yuck.

Message-ID: <[EMAIL PROTECTED]>
Am upgrading my E34 525i touring to 740i brakes. First stage was to change
from solid to vented rear rotors, requiring E32 calipers and the carriers.
As a result I have a good pair of rear calpers, that will fit all E34 (518
to 535i) for sale. Calipers worked fine, no sticking or pulling. I just
wanted to have vented rears. Calipers are $50 for the pair to a good home,
USPS flat rate shipping is around $10 in the US. Contact me off-line.
Will have the fronts for sale in 1-2 months, and I'll make a similar
announcement.
These (rear) calipers also work on the E28 -- you will need to change to the
E34 rear solid rotor.
Contact me off-line.

Subject: <FS> TRX tires
Message-ID: <[EMAIL PROTECTED]>
Anyone interested in purchasing or know someone who is, a set of two TRX
tires?
Size 220/55 x 390 in very good shape. I can send pictures to those
interested. Tread depth is 7 to 8/32's across the tires. They've been
stored out of the sun and horizontally. I'll have to unmount them from the
E23 wheels unless someone wants them as well.
Asking $70/tire.
If within a half hour of the SF Bay Area, I'll deliver, otherwise buyer
pays shipping.
