Read my post again. I noticed my car stopped self centering when I switched back to run flats. Steering is very numb around the centre. Car is awful. I'm currently deciding if I should go with not run flat 19 tyres or switch to 18 inch wheels with not run flats.

That's very very strange. Why would tyres so change the whole behaviour of the steering?

If this is correct, I was wrong about my friend's 530d not self-centering, considering that wasn't on run-flats.

Switching between RFTS and not RFTS on my car had no effect on centring but it does now feed back on low frequency undulations in the road. With RFTS the steering was steady, but with non RFTS if I go over undulating/uneven road, the steering turns/wobbles back and forth. I'm guessing its down to the programming of the electric steering, expecting run flats and their characteristics... which I've now changed.

Its a minor thing I can live with for the fact the car is now super liveable with...

It might not be a run flat thing. It might just be tyre related. It might be wider tyres or lower profile tyres or just grippier tyres - no idea. All I know is I swapped my wheels from the not run flat 17 inch winter wheels and tyres to the original 19 inch run flat wheels and tyres it came with and noticed the steering felt numb around the centre and didn't self centre. It will self centre to an extent but the very last part to absolute centre is missed.

Whereas the one I had didn't have ANY self-centering action at all... weird.

I have not got all of my BMW anymore its in bits made a nice coffie table and clock out of what was left hade a small problem with a big Tree or was a big problem with a smaal tree such is life

Self aligning torque is strongly influenced by trail. Trail consists of a mechanical portion and a pneumatic portion. The pneumatic portion is down to the tyre. Tyres with stiffer sidewalls tend to have less pneumatic trail than ones with softer sidewalls.

Tyres is steering.

I'm sorry but I can't take RoverP6B's criticisms on BMW seriously after the 'tell me I'm wrong' article on the F10 M5.

He's a clueless bore, that seems to dislike BMW's yet hangs around the BMW forum like a dodgy ice cream man at a primary school fete.

Dislike BMWs? Oh, that would be why I've owned nothing else for the last nineteen years?

I absolute bloody LOVE BMWs - which is WHY I've given the F10/F11 a hard time - because it is so very far removed from what I consider to be the essence of BMW. Now, my E39 is a great deal bigger and half a ton heavier than my E30, it has 50% more cylinders in its engine and it isn't as agile nor as inclined to spin, thanks to the modern multi-link arrangement in place of the E30's semi flailing arm rear end, but I can still feel the E30 DNA when I drive it hard - DNA going back to the original Neue Klasse saloons of the mid 1960s. I'd heard that the E60/61 was a more focussed driver's car than the E39, so I had hoped BMW were continuing to build genuinely sporting saloons and estates - but a month spent in an F11 showed that this is no longer the case. There was no agility whatsoever, it's more the size of an E38 7-series than an E39 5-series and the total absence of steering feel made it impossible to drive with any confidence.

Zzzzz

Anyway this thread has been spammed enough, any more pics?

More of the grey 4 series please.

How about my newly acquired Fun car. E46 coupe fitted with a 5.7 litre small block chevy. It's angry, noisy, hard and brutal.

[RoverP6B]

I'm not sure how I feel about that given that S54s are available and tunable, as are M62s and S62s, and I tend to like to keep modifications OEM or at least within the overall character of the car, but I have to admit that the idea of a big angry American V8 in a small BMW does sound like fun.

I love the insanity of it but if I recall it's not actually any more powerful than an M3??

Nice project and certainly something different!

If it isn't - the CSB is arguably the easiest and cheapest engine in the world to tune.

When you're buying a fun car, insanity wins. I've only ever had one passenger ride in an e46 M3 and it didn't really impress me. That was a few years ago. I also test drove the csl when they were newish but didn't really get it. I believe they like to be revved and I didn't really rev the csl. Fast forward 10 years and I've gone to view this car. The test drive impressed me within 15 seconds and I knew I had to have it. Forget finesse and refinement and think - insanity is a good word. Check out this torque curve. It's got 400 ft lbs at 2750 revs.

Hi everyone, I'm new to this so not sure if it's the right place to ask. Can anyone recommend any good car wrapping companies near Blackpool / Lancashire?

Any help would be appreciated, cheers guys

Understood - torque is lovely! There's someone here has a Z4M (same engine as E46 M3) with a centrifugal supercharger for 520bhp, forget the torque figure but it was fairly high. Do you know what engine your car started out with?

Torque is a red herring. Power output at a given RPM will give the indication on how fast a car is. 'Power' (expressed in units of KW and HP) is the energy delivered. Every object that moves needs energy to do so.

You could have an engine with 5200 lb/ft of torque at 10rpm, the end result is 10bhp. It's not going to be very fast.

It would be more accurate to say "it generates 270bhp at 3000rpm, and it revs to 6000rpm". That says a lot more about the performance.
