228,000 had the car into Jon @ Auto38 to see if he could diagnose the shimmy I’m experiencing at 80-100km and upon braking. Everything in the front is tight, worn upper control arm in the rear. He thought it could just be tyres. So today @mossline and I swapped wheels. We also put mine on his for extra validation. No dice. My car still wobbles and his with my wheels doesn’t. Good to be able to rule that out though. so guess I’ll replace the rear arms and take it from there. After seeing @Jacko’s glossy car I bought some soft99 car wax (for light coloured cars) and went about my commiserations waxing the beast. photos of it glossed up to follow tomorrow. side note, the E30 has a lot of play in the drivetrain so it was drop one off pick one up at Auto38 this week ?‍♂️

Failed to remove the oil filter cap for an oil change so skipped that and moved on to installing the M3 front control arms. I was utterly stoked to find all of the nuts and bolts are new(ish) and had anti-seize on the threads. Somebody has loved this one in the past. Low and behold, as I inspected the current upper arms I noted that they were poly-bushed but removed one anyway to check it out. Turns out it's already an M3 arm, same length as the one I had to put in from the M3... Edit: I've been advised that the M3 and stock arms are the same length, only the bushing is better, the M3 one is far superior to the stock one. The poly bush negates that advantage. So, unless I'm advised otherwise the poly-bushed ones will go back in and I'll sell I've sold (1 hour) the M3 ones to recover my costs. Lower arms are definitely stock... And the M3 bushing is obviously far superior... Should finish tomorrow, then off to Autolign for an alignment.

There is a big ass socket thing for getting them off, supercheap etc sell em. I have a couple if you want one.

Sorry but you have a basic misunderstanding of what angular velocity is, radius has no effect on it, none, nada. That why it is measured in angle unit per time, not a distance unit. https://en.wikipedia.org/wiki/Angular_velocity Constant rotational frequency does indeed translate in to constant angular velocity. This is basic stuff, I'm quite surprised you've got so far through the theory to a result without understanding the basics. That's why when you put in 5000rpm to one of the many, many online calcs, you get an angular velocity output (523rad/s) with no mention of radius anywhere. https://www.calculator.org/properties/angular_velocity.html The example demonstrates how you are getting confused. If you use linear velocity instead of angular, the linear equations work, however, earlier on you're mixing the two and using both rotational inertia, and linear velocity, this doesn't work. Which is what leads you to a conclusion where energy is not conserved across the examples (this should have been a red flag to you early on).

Hey Adrian, Good to chat on Thursday. Finally sat down and read through this. You've put a hell of a lot of time and $ into it that's for sure. Here's what I did with the last pieces of mine when it was written off. https://imgur.com/gallery/np7tA Hope it gives you a laugh. Cheers, Sam

Anyone have an Air Condenser available for the N54 for cheap?

I think Milan ( @E... , I think) is considering a group buy for the BTBs.

Awesome, you'll like the results. I found it took me a few minutes to get use to the new pointy front end.

The cap is in really good condition so I don't want to damage it. The tool I'm using is suitable, it just wont grip hard enough (so not really suitable lol). I've seen the proper tool but thought I'd get away without it. @Jacko - I might take you up on the offer, you'll need to come to our July coffee meet! ?

Yeah, use the proper tool or you will mangle and gouge the cap trying to take it off and you wont be able to torque it up correctly (which is probably why its so tight now).

I hope this goes to a good home. I'd so buy this if didn't already have both a M62TU V8 BMW and a silver BMW sports sedan ?

Good luck....I'd get the engine hot before starting the job so it's warm by the time you get there.

Bit of a thread dig, but as there is still no sign of an M4 Gran Coupe, the other part of this “news” might also be incorrect. You never know ?

Im after the same thing. Need a replacement m43b18. Anyone have one? Or know where to source one? Becoming a bit scarce these days

Un-wrapped some goodies for it ?

Some images I hadn't posted on here (pre tints) Battery is on the charger.
