It was also reinforced on the PTG M3's, I remember that. I think I'll go with a blade adjustment. Can you tell me the tube size?

Another work day on the car.

Received all the parts to reassemble the rear suspension, except a retaining clip for a wheel bearing that was missing from the box package. I broke the one that was on the trailing arm, so I couldn't reuse it (damn that ***** was stuck in the rust.)

Installed the trailing arm M3 outer bearings. The lower one was a PITA, mainly because it couldn't be pressed in as the trailing arm wouldn't fit on the press.




Also installed the upper control arm inner bearing from GC. It's nice but could be a little tighter in it's hole.






I was able to complete the whole right side. The reversed Moton fits perfectly.
Calipers will be resealed and rebuilt shortly.





You will notice the upper CA has been painted, It looked like crap after getting sandblasted. Anyways, I'm trying to get the Woodward upper link if I can find some already made for the E46.

The car owner decided to do his own oil cooler bracket. It think it's a little too beefed up, but don't worry, it's Aluminum.



Some parts came in last week.
The Tilton floor pedal box with all the necessary hardware.
I will wait to install this a little later in the season, because it will be done along with the driver position being moved further back. A longer Woodward steering column, longer shift rod and AGK shifter will be used.




The wonderful Bimmerworld exhaust system. Cant wait to match this with the SS headers.(Hope it will fit). The construction is awesome, and it's very light.



I think I never posted pictures of the car as it is right now. The new colors will be pretty different from this.




My work partner Daniel cleaning up my tool mess.



The team owner just bought this Featherlight trailer to haul the racing rig. Slightly used, it's almost like new. We can fit 3 cars in there, but only the Bimmer and his Merc 500SL will go in there.







He also got this 1998 Volvo VN770 for really cheap to haul the trailer.
Cheap means, he has to redo all the air hoses, brakes, bearings, bushings.



New turbo as well, funny thing is that this is a Detroit Diesel 430/470, but they painted it with the Cummins colours.



He also shortened the frame and removed an axle(the trailer rig is so light, double axles are not necessary). Switched to a single big tire setup also.


They painted the frame also. The cab will be painted black too.


This will be the last update for the next 5-6 weeks. I just bought a house and it will be a major home improvement project,
I will still order parts though:
- Bimmerworld spherical front control arms
- GC Adjustable Bump Tie Rods(Spares)
- BMW Motorsport Front Sway Bar Kit for E46
- AKG STAGE II Motorsport Quick Shifter
- UUC DSSR for E46 M3

See ya in 5 weeks (I may be a little tired then)

You're probably aware of this, but if you do go with a tubular upper rear control arm you'll have to notch the chassis.

PS-I'm jealous of that trailer.

Looking good!

Will the Bimmerworld M3 race exhaust fit the M54? I guess you're probably not running remotely stock headers.

We'll see. It shouldn't be too far. Supersprint E36 Euro Headers. No engine in the car to test fit.

Well let us know how it goes. I'm sure nobody is ever going to mass-produce an exhaust that perfect for the M54, but if it's easy to have a muffler shop adapt it, that's a nice option to have.

You are not worried about the loads in the bolt holding the strut to the rear knuckle? That bolt location is in single shear and was only designed for a damper load, not the full weight of the car.

This is done rather commonly and it works, although I have heard of the occasional bolt bending, but mainly on e30's.

Understand. You might want to put the bolt in double shear by building a bracket that interfaces the outside of your bolt to the threaded feature just below your bolt. That will distribute the load through both of those threaded features, not just the top one. Good luck, build looks great.

After 7 weeks off, I'm Back!

Pics of all the work that was done while I wasn't there. New engine back in the car. New much bigger radiator.



The Bimmerworld race exhaust system had to be fitted to the SS header, but it fits. To bad to job was poorly done with regular steel pipe. He didn't have any stainless steel around.






AKG Solid race shifter along with the DSSR shift rod. The shift feel is incredible.


The BMW Motorsports front sway bar and Bimmerworld race control arms. Also new spherical tie-rods, old ones are now spares.






The car will leave this week for chagautosport.com for the Vipec V88 install and dyno tuning. More to come.

For me, I just made shorter inserts for the shock and used a shorter bolt. Knock on wood, I have never had the bolt fail and I have been running coil overs for many years. I even use anti sieze on it as I change springs all of the time and just don't want any problems.

For some reason, Moton makes these real long inserts that utilize the stock shock bolt. That's a Koni on my car but it is a direct replacement for a Moton (when it comes to fitment).

Here's what I got:

Probably because the rebound adjustment is there. I never saw this bolt fail ever on any BMW.

My old motons had the rebound there (which was the same shock) but the Koni has rebound and compression in that spot. A stock 5 speed flywheel bolt ends up coming out to the perfect length.

what are the benefits of a true coilover system in the rear?

Its really quick to change the spring as the lower perch is slotted. Remove the strut bolt, lift and slide the perch, replace spring, et voila!
Also more height adjustment is available this way.

Would you personally recommend true coils on a street car that only got on the track a few times a year?
