I'm borrowing Ben's that I believe he bought at Murray's (insert
Kragen's, Autozone, or whatever nationwide parts store here). You can
use some of your transmission bolts but otherwise you'll have to buy
long M12x(pitch)x(4 or 5 inch) bolts. I don't know what the pitch of
the bolt is, guessing coarse.
BTW when you start a subject you don't need Re: at the beginning, that
just means someone is replying. So your messages look like a reply,
which they are not. :-)

I prefer 4 point stands over 3 point stands - more stable though they do
take up more floor space.

The wear bars indicate too shallow a tread for water
drainage. There is no problem with thin treads for
track use, except that the fancy wet traction
undertread that Bridgestone uses may tear easily when
the tread is thin. On the other hand, thin treads are
more stable and more resistant to tearing. Keep an
eye on them.

The only thing I would add to that is that depending
on how much track usage they have, the excessive heat
cycling may harden the rubber compound and cause a
reduction in grip. Not a risk, per se, but something
to be aware of as you continue to use them.
My old AVS Intermediates that have seen > 10 track
days and an equal or greater number of skidpad days
still have maybe 1 mm of tread, but they're so hard
they have almost no grip, even in the dry. One hint
is if the rubber has turned a bluish color... :-)

Last time out on my S0-3s with the rears at and beyond the wear bars wasn't any fun
because they didn't have much traction. That could be risky. This was on a 97 M3,
so your milage may vary.

Kurt, doesn't the organizing body for your group's track days have a
minimum tread depth requirement? Your question may be moot.

freaking nuts. you can get them at sticker at a bunch of dealers which
aren't even that far from ATL, let alone places like Westchester (BMW NA
owned dealer in NY) which is right next to huge airports & will recommend
which shuttle to pick you up to take you to them to pick up your car.

wrong Neil. Neil Maller was who I had in mind as well as you
apparently. we don't need to go into Neil D's penchant for non-
functional evaluations of vehicles :-P
> You were apparently so distinctly underwhelmed you
> bought an STi?????? :^P
nope. I had never driven an WRX (or STi) prior to getting
mine and haven't been to the auto show with Neil. I'd
probably not have thought nearly as badly of the WRX
if I hadn't 20k+ miles in the STi behind me, as I'm sure it's
a very nice car when viewed w/o the distorting prism of the
STi's vast difference in character.

Message-ID: <[EMAIL PROTECTED]>
My son noticed a difference in the intake manifold vacuum lines between the
325is and his 325i. The "iS" has a single large lines off the intake "box"
whereas the "i" has two lines coupled at a point to a check valve.
Any idea why the difference?

The two line setup was for earlier cars where they used a vacuum
amplifier to ensure high vacuum to the brake booster. In later cars,
they found they didn't need the higher vacuum and went to a single hose.

Don't worry, you will be the first to know if I get another E36 M3 for track
use. Especially since McCoy has developed the turbo kit for the M50/S50
motors. Was a passenger in his 93 325i test mule which felt faster than my
LTW M3, very impressive.

Hmmmm, maybe I need to start workin' McCoy on a proper S14 turbo.......
Better yet, Mike, turbo a LTW!!!!!!

P.S. Mike only wants me to know he's got one so I'll hit the track & can
spank me six ways from Sunday so I can't say I smoked every 6-cyl M3 I
shared a track with anymore!!!!

I finally got my Roundel and checked out the picture that has generated the
controversy. And also the picture of Sal. Sorry to say that I cannot take
credit for the way Donna's car is being driven there, it is Brant Miller
(not related) behind the wheel in that shot, not me. Brant was in C Group,
and given the various skill levels in that group, an E30 325i passing an
E46 M3 is very possible. Although, I doubt that it would be happening on
the banked oval part of the track. It would more likely take place
somewhere on the infield.

I'm wondering if anyone in the LA, California area has
the E30/36/46 control arm pushing puller and installer
tools, and/or the rear trailing arm bushing puller and
installer tools for rental or borrowing -- they'd be a
huge help.
Thanks,

You can try place like Autozone where you can rent
tools for free. I have done it in the past.

The M20 is a 2 valve head. The piston crown sticks up
in the right spots to form a quench against the
combustion chamber, clearance for the 2 valves, and a
pocket for combustion around the spark plug. The M50
has the valves, quench and plug in a different
location. The M50 piston is flat or dished with a
qhench producing region around the periphery. I
suspect that the M20 piston would hit the M50 head and
prevent the engine from turning.
The piston and head should be made for each other to
generate proper chamber turbulence.
