My Ride: Any BMW with 4wheels
Thanks for the interest guys. Sorry for the slow replies here. The One Lap went well (cleaned up in our class and 13th overall, would have been top BMW if I hadn't blown off track at 100+ in the reain at TWS), then race season picked up (5 races in 7 weeks), ending with us wrecking all 3 cars. We got them all fixed, won our first race of the year, and came close in Mosport recently until we had some minor issues. That is my sob story, now back to it...

We have been making some progress. The chassis build takes the longest when you do it right. After that is done, it is only a matter of painting it, then assembling.

Fitting the driveline - one of the projects we have to get sorted out before cage building can start full speed.





Installing the fuel cell. Here is the basic frame. Working on setting depth to allow the use of a proper diffusor.



Back side of the firewall - the engine is being moved back a bit.

Basic framework for the back half of the cage, more to come...



Here is the main hoop - welded directly to the car B-pillar, no gusseting needed.



Front A-pillar bar


Looking down on the dash area


And the side view...where's that bar? One of the side jobs is in the background...

Starting to fit pedals and prepping to do the front part of the cage through the firewall.

Pedals from the inside


Pedals from the outside - initial stage of fitment...


Strut tower - before we whack it off.


Rear fuel cell and airjack


Rear shock area. We are running Moton Triple race dampers and will make a bolt-on clevis to mount underneath here.


Couple of random cage pictures




Fuel and airjack lines being built - it will all come back out before paint, then will be a direct drop-in when we get the shell back.


Driver's seat mount

I think this cage goes right over most people's heads. The details and fabrication quality is amazing. If I ever do another E46....

Keep the pics coming!

Carbon time! Hanging all the carbon (all 45 pounds of it...). If you ever mess with this stuff, wear a mask - it doesn't like to leave your lungs once it gets in...



The trunk includes hardpoints for a wing and the structure is incredibly rigid. We prefered this solution for ease of access to dampers, plus it saves us some work on the airjack port and drybreak.

I don't use PM but you guys can always email me. I typically don't have time to monitor forums and don't want people getting mad when I was supposed to answer something they asked me publicly. I am not hard to locate

Doors are $2700 for the pair.

Damn! Those are some expensive doors. How much weight is saved over skinning the stock doors?

About 15 over a really light gutted door and maybe 35 over stock. Per.

No - they are made to order. Will work with ALMS type windows. The doors aren't really street parts - you would need a cage since they lack door bars for protection.

James,

E46 Coupe door with only inside trim removed is 65 lbs each.

Would it be possible to weigh the carbon doors once the door latches and hinges are installed?

For anyone else interested in CF doors, the ones from europe are 2200 euros....or over $4k USD. Bimmerworld has excellent pricing on this.

You have a bolt in roll bar, not a cage. There's a huge difference...

Look at ALMS pictures - it is a custom made piece of lexan - not legal for most club and even pro cars in the US.

We only add about 1.5 pounds with this stuff after we lightened them. Mirrors are another 2-3.
