Big BMW Bill! Advice guys?

[Ewazix]

I don't like the idea of welded cracked wheels, I know Frigg all about welding but I'll express an expert opinion anyway - a lot of places won't even touch most work if this type as the welds are either ugly, leaky or break up again. None of which is good. Unfortunately the weld process weakens the alloy unless a lot of expert care is taken and its an appropriate area of damage.

Fixed that for you.... :roll:

Im not sure what you think you are saying, or why. :?
Far too often people spout advice giving the impression they (personally) are qualified on a topic, I made it crystal clear I'm not, but that according to people who actually know about welding cast or forged aluminium alloy metals its a very unreliable process requiring knowledge of the exact material spec used as the inclusions and impurities are what cause the issues. Its less forgiving than welding steel.
The basis for my self confessed meager knowledge is that, in a previous career I was responsible for monitoring test and compliance certification of various components used in nuclear power stations, including materials integrity, and fixings, including welding. Hence why I'd happily risk a welded head, but not a wheel.
BTW If you feel the urge to 'fix' my posts with smart arsed eye rolls, please read what I've written and assume I'm actually trying to be helpful, and ACCURATE before bothering. Cheers 8)

Impressive and conclusive.

Don't stress mate, it was an attempt at injecting some humour into a thread where people were becoming very polarised in their views - not all of them correct - witness Busterboo's MOT failure statement.

Having said that you knew nothing about welding, you then went on to list some very specific reasons why welding wasn't a good thing - I was merely highlighting the contradiction in your response.

You were holding out on us! You clearly know way more about the topic than the average guy in the street and I bow to your opinion and apologise if it came across as anything other than gentle ribbing...

Update:

I have now additionally ordered a full set of Michelin PS4 tyres to go with the new alloys.
My mechanic is going to take a look at the front shock for a final conclusive look when installing the above.
The Window and Door pin repair I have been quoted £110 for both.

If it's not too late try changing to the Michelin PS4S. They are the UHP version.

I've recently changed to them from PSS and they are seriously impressive for grip. I'm giving it full beans in 3rd with no traction control lights! In a non-tuned car you could probably get complete traction in second gear.

Sorry typo above. They are the PS4S )). Sounds great

Thanks!

Real progress. Good to hear.

And you'll enjoy the Michelins.

I had one leaky shock and within 6 months, 2 were gone completely and another leaking. 35is too. I dumped the adaptive suspension and dropped 1600 quid for KW3 Coilovers with the emulator to disable the adaptive suspension. Best decision ever. Would have been twice that to get the OEM versions an I get to customise the ride to how I want.

I see the adaptive suspension on these cars becoming like the air ride on AMG Mercs. People will just start chopping it out due to the expense.

I do like the adaptive ride but if I was faced with a £3k for a full overhaul of the shocks then I'd be looking elsewhere too. I really wouldn't own a 35i or 35is without warranty though, you need balls of steel to run a car like this out of your own pocket!
