This must be at least as rare as the E91 330i manual I was asking about earlier (and must be the ultimate e91). 400bhp!

E91 line-up at work today.


248 (06-09-2017) by Chris Reeves, on Flickr

From left to right:

318d (M47) - poverty spec.

335i M Sport (N54) - owned by friend at work, pano roof, Nav, Xenons etc. Auto. Keep telling him to remove the grill stickers!

330i M Sport (N52) - mine, Manual, Scorpion Exhaust, Birds B3 Suspension.

In other news, I discovered that I can fir a 3m long bit of conduit in the car and everything shuts - that's about as long an item as I reckon you can manage though. Given how often I appear to be load lugging stuff, and half the miles I do are probably with a bike in the back - I really can't do without an estate car! #BecauseEstateCar

You can get 3x3m lengths of 3x2" in as well. I didn't know that until I had to try. And as I walked up to the car I really did start to wonder!

I've been tooling around a lot in the Mrs' F21 125i this last few weeks, and I've really got used to the M Performance brakes. I'm increasingly coming round to the idea of upgrading - will probably tie it in with a general suspension refresh next year.

Did you fir the B3 suspension yourself? If so, what difference did it make? Would love to hear from someone first hand, so to speak.

Came with it - but when I rebuilt the rear end, I essentially un fitted and re-fitted it - all fits easily.

It's firm (slightly less than stock M Sport iirc), but it's well controlled and nicely damped - doesn't feel harsh, and hitting a pot hole isn't the end of the world. I think I have some wobbly subframe bushings that I haven't swapped out yet, and I'm not happy with one of the powerflex bushings - so handling is limited a tiny bit (bit of shimmy still) - but you can feel the underlying chassis and spring/damper set is well controlled. When the dampers start to get tired - I won't be using as an excuse for an Ohlins kit or anything (unless I'm super flush with cash at the time!) - I'll be sending them back to Bilstein to get rebuilt.

The birds roll bars compliment the LSD apparently - I really wish I had one of them!

Yeah I read some technical mumbo jumbo recently about how if you have an open diff on a modern bmw they make the suspension and roll bars match but I cant remember now which way round it is - as in stiffer for open or softer for open. Thinking out loudly it might make sense to have a stiffer rear roll bar with an open diff because it might force the wheel without any load into the ground more and stop it spinning up. But I'm definitely just rambling now. The point is bmw tweak the setup between open and limited slip. So just changing the diff in isolation doesn't really work according to what I read but I think it must help surely. Do you guys notice much wheel spin getting off the line? Does these cars apply the brakes to one wheel to limit slip?

Wow - I think my waffle was relatively accurate.

So it's about £4250 to have the suspension, diff and ARBs fitted at birds. Crikey!

I don't think that's too bad tbh, quality mods which have been tried and tested are never cheap. Although it's not something that I'll ever do as that's over 50% of the value of my car!

I wander what that Alpina is like to drive and how it would compare to a Birds'ed 335i with a remap.

Yes, turning a £5k 330i into a £10k one isn't that appealing.

I wonder if the mods work well individually. For example, I never found body roll or traction to be excessive on my 325i but the ride and skipping rear end was a problem. Perhaps the springs and dampers would have been enough for me.

Yes the B3 Touring has sold, there is a thread running on the Alpina Forum. I was tempted, but struggled with the asking price and the miles. So I've decided to hang onto my 330i a little longer.

Softer rear anti roll bar to give some more compliance with an open diff. The birds kit on mine went with much stiffer anti roll bars, stiffer bushing and revised springs and damper valving. That is wth the Quaife ATB.
