Obioban's 2005 IR/IR Coupe

[1bluemcm]

I'm discovering that the list of NLA parts for M coupe/roadster seems to get bigger and quickly. Problems with low production numbers. I also try to pick up extras of things that seem to be getting harder and harder to find.

[Obioban]

Kind of a boring update, but the old driver door arm rest cracked, so I bought a new one. Feels like the kind of part that will soon be NLA.

Any update? Can't have the mythical obioban m3 off the road!

Ha, I’ve been driving it.

Pressure tested it and it held pressure. No further coolant has disappeared.

Hopefully it just burped over winter 😜

I hope not.

Zero coolant smell in the cabin.

Going to pressure test the system.

Heater core leaking?

Hmm. Just pulled the M3 out of winter storage and the coolant was low.

No sign in the oil.

No puddle or residue under the car.

Where did it go?

Waiting to see how this CF driveshaft goes...

Just bought a used F8X driveshaft. Going to follow Altaran's lead and put e46 M flanges on it, for a hopefully OE qualify CF driveshaft on the cheap.

Yes! Looking forward to your feedback.

[Obioban]

When I saw what Altaran did I actually thought of you as I figured six seconds would elapse between you seeing it and you buying one. lol

I don't know how to feel about being so predicable.

I'm very tempted to do the same, just a bit scared of the increased labor required to get the driveshaft on and off. Looking forward to the reviews.

Wow!! Still good to see this build going from the old M3F days.

I'm sad I lost 15 years on M3F build thread

Ian's latest updates to his car, specifically the SLONT plate and the strut brace are amazing product, sharing some views and feedback:

Conclusion: both the front and rear end upgrades make a HUGE difference. Car feels much more on its toes, the time of "setting up" the suspension to make a turn is greatly decreased, front end feels excited and ready to turn in, and significant improvement in decrease in road noise.

Background: I spent 3 hours driving my M3 down to PA and then spent 30 minutes driving Ian's back. Our cars are virtually identical in setup with the exception of the Slon strut brace and trunk plate (suspension settings and mods in particular are virtually the same, done by the same two people). I can't think of a better back to back comparison.

Just for some context here-- Sergei's car is set up as identically as you can imagine to my car, other than the Slon parts (which will likely be going in shortly, after driving my car with them). He has been working on my cars, and I have been working on his cars, for almost 20 years.

He drove 3 hours to where I was, and then almost immediately drove my car. The most back to back possible back to back comparison.

He does point out something I think I failed to fully put into works in my original post. With a stock car, you kind of turn in, wait for the car to take a set, and then drive the car through the corner. I previously had assumed that waiting for the car to take a set was the tires rolling over. With the Slon parts, that taking a set period is significantly reduced-- which makes me think what I was actually feeling was the chassis loading up/flexing as far as it was going to flex for the load being applied by the corner.
