E46 & E90 (non M Power), handling query.....

Don't forget that RWD is a killer and if you ever switch the engine on and actually drive it then it's a 50/50 if you'll reach the end of the journey.

no-no-no its 50/50 weight distribution, making it the ultimate driving machine and it certainly sounds like merlin got a thrill from it :eek:
 
I love the 50/50 claim.

It may be 50/50 but the actual weight is so far away from the centre of rotation that they have a large PMI (Polar moment of intertia)
 
If you bought from dealer, I'd explain to them what your finding and ask to use one of the demo's in same spec for a few hours. Try again and see if it's replicated.

EDIT: just saw above post. I know of a few poeple who have ditched the run flat's within a couple of thousand miles. I've never tried them but I have been told (have no idea if true or not) that when getting close to the limit the stiffer tyre wall lets go quicker with little or no feedback. Just a suggestion.

Fair old distance between engine and rear diff/rear axle.

Not difficult to get it pointing backwards.
 
Yeah thats what I mean, stick all the weight in the back as far as you can back and you get 50:50 still but a equally heavy back end.

No what I mean is - would that contribute towards oversteer on braking when under lateral load?
 
It was either a road, tyre, car or driver issue (call me Holmes). Too much braking in the bend and I would expect the rear end to go loose but a little to settle the balance and remove some pace should not cause an issue to my mind, lard burning or not and I would expect you to be experienced enough to know that, so I feel something in the car may be somewhat off, probably those awful run shats.
 
dunno, the M57 lump in E90 / E60 guise has had a fair bit of aluminium fettling. Can't see it being that drastically different in weight to the petrols now. Still 100 odd kilos though.

I honestly think you'll find its the RFT's

Oh and 50:50 is really a complete joke. It may be close front to back, but side to side is laughable ironically.
 
Is the brake bias different between the 2 models and you are applying more braking force to the rears than you are in the other even with the same overall braking power?
 
I know exactly what you are experiencing...my e90 330d M did this with alarming ease, but only on one particular corner on my old commute. A long, fast sweeper with increasing off-camber. Initially I put it down to the braking system which diverts to where it sees fit (possibly unbalancing an already unbalanced car) and the road but I also had some tramlining issues with the PS2 ZP's and after a geo session to sort that out, it also pretty much ironed out that particular corner.

Not the fun, progressive type of oversteer, is it?
 
Yes, its as great as coming off the throttle & onto the brakes in mid bend.....

Never heard of trail braking?

This braking only in straight lines should only be taught when they tell you 10 to 2 and passing hands through the wheel only.

I would have a look at Geo too, don't assume they are bang on from the factory.

Certainly isn't! It feels like someone is lifting up the rear wheels off the road, not fun because it feels like it's going to snap and swap ends and there's nothing you can do about it. It doesn't swap ends - but initially it feels like it's going to because the rear just feels like it's floating. Totally different to power oversteer when you can feel through your backside the rear is down on the deck.
