still trembling

Sorry to hear that

The feeling here in the US is that the BMW dealers no longer have the experience or knowledge to work on the 8 series cars.

A good independent shop with some positive experience with our cars is a good thing to find. But if they start out telling you how bad the V12 is before they do anything, it is not the right shop to be in

I have heard of main dealers changing all of the engine computers plus the DK motors without fixing the limp home problem at a cost in the thousands. The problem was later usually found to be a bad spark plug or something as simple.

Are any of the French members near where you are located? Perhaps someone has a trusted shop near you?

Thats Disgracefull, Bm dealers in France hang your head in shame

Why not replace every suspension part at the front that's not already been renewed then you would have a new set up

Maybe also get your tires checked for imperfections

Ziggy, Sorry to hear that, but, surely they're taking the piss?

840 Euros for 2 tyres? I just bought from "Kwick Fit" here, 2 rear 275 x 17 x 40 Michelin Pilot Sports for £ 370.00 . And, I know that tyres are cheaper in Europe than in the UK.

Wheel judder ? Yes, I had the same problem, but only really under braking. Asked the specialist to check it out, with the informed knowledge from this site that it's normally control arm bushes that causes this.

Result, they renewed the front control arm bushes plus the 2 rear lower swing arm bushes. Total cost with an Oil Service and renewal of the main windscreen washer pump... £ 740.00.

Result 2 , Brakes are still break dancing with medium braking effort. Fine under HARD braking.

Now don't really know whether to replace the discs with standard items before the next MOT ( March) or to bite the bullet and fit the big Brembo kit at approx £1200.00.

I think you'll need to put your hand deeper in your pocket mate

Dont think its possible to do the BIG brakes for less than £2500 if your after brembo.

Have a look at http://www.hispecmotorsport.co.uk they are around £1500.

Wheel repair specialist's Can make good these repairs but i guess you should always be wary of the long term cost, only you can make that decission

elyptic wheels are usually the result of fitting large diameter "bore centered wheels(eg from a 540). If you check you may find a difference in diameters of around 2 mm.

This is a common problems when tyre & wheel sellers don't know there is a difference on E31's. Mine had plastic tape wrapped around the hubs when I bought the car.

The aftermarket makes spacer rings, hub centre rings or any name you wish to use, to take up the gap and give perectly round rims agai.

Sorry bout that. Must have been pissed.

E34 wheels and most non E31 have a lerger centre bore. The centre bore locates the wheel to allow it to spin perfectly round.

E31 uses a smaller bore and while large bore wheels physically bolt up they wno't run true circles as they cannot "locate" on the hub.

The solution is to reduce the diameter of the wheel bore to the same diameter as required on the e31 with a spacer ring usually forged from aluminium.

Opinons from BMW will be expectably %#@! but I used them on my replica Throwing stars. My problem was that the wheel was running elyptically not circular.

Check the bore diameter on the wheel Then check the diameter of the hub where the bore should seat. You should not be able to fit more than a sheet of paper between the surfaces.

Cheers

theo here just might be on to something.
I've had the same kind of problem earlier on other BMW's. and 2mm will make a really shakey ride.

the simplest way to explane this is. when you put youre wheel on, is it tight and does it stay on the hub without any bolts in. or do you have play and the wheel needs to be held firmly in place to get it on.
once the wheel is on the hub (no bolts) you should not be able to move the wheel up, down or sideways at all, a really snugg fit is what you need.

the quick fix is a durable tape, i.e duct tape. (just for checking)
the wheel should have plastic or metal rings, where I live their called centering rings. any wheel shop should have these.

I personally think Ziggy is trying to say that his Standard e31 wheels are buckled or less than perfectly round , or am i also barking up the wrong tree

Good description Noggie!

The tape will centre the wheel for a short time but it should not be viewed as the solution. Mine had tape but when you hit some rough raod and under braking hard the wheel can still move as the clamping prssure of the bolts is all that is keeping it in a circular rotation and it will go "out of round fast'

I learned the hard way

Cheers

Steve 840.

You are right, must have skipped Ziggy's post somehow.
I just found it hard to belive that all 4 wheels are buckled up.

And its not a spacer, it's just a little ring you put in the center hole of the wheel to make the diameter smaler and fit perfectly on the wheelbearing housing.

Found these while flicking thorugh fleabay - might help!!??!!

Theo is absolutely right.
Try the duct tape and if it works for you, get the proper spacers/centering rings.
I have used tape and it has worked very well in the past.
Don't give up ziggy.
