Not quite :).

I am going to research and gain some further opinions before making a further decision. Readinf online some people seem fine with welding some are not. What concerns me is that when ever i sell the car in the distant future aftermarket wheels put alot of people off. Liking the BBS CHRs though. And the CIRs :)

I don't like the idea of welded cracked wheels, I know Frigg all about welding but 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.

You actually do not need to tell the insurer as fixing a cracked rim is not a modification! :headbang:

For petes sake, do you tell your insurer if you get a puncture repaired? How about if you leave the house with odd socks on?

I appreciate this is an E89, but I replaced both my front shocks on my E85 in 90 mins (novice here with a little help from a mechanic friend)

The only cost was parts

Hi Sunnydays, you appear to be having a rough time getting the Zeds Gremlins sorted. Hang in there it will be worthwhile.

We have recently had the 326M wheels refurbed and have switched away from the run-flats. We went for comfort on the tyres rather than outright performance. Uniroyal RT3's in 235/35 at front and 255/35 at the rear. Improvement in comfort level is amazing and I now have much less concern that the wheels will develop cracks. Note : previous wheels were not cracked but refurb involved adding weld material to build up rim profile before re-machining. The rim profile had been ruined by cosmetic repair work carried out by BMW main dealership in March 2017, and charged to previous owner. I decided just to pay for a decent professional job rather than give the bodger another go.

The 326M 19" wheels do look great, my refurb was done through a local firm who stripped the tires off and then sent the wheels off to a specialist in Milton Keynes, (6 day turn around) . Wheel refurb was £528 incl (I know this is not cheap) and tires were £400 supply only from local garage with free fitment by the local firm who sent the wheels away. Another £70 for centre caps and wheel decals and we will be all fixed up for £1000.

I found my e89 had a cracked 17 inch alloy the week after I bought the car. This was my first ever cracked alloy after 10 years of bmw ownership. When I started my research the scary stuff wasn't that a crack can be repaired but that the alloy has to be heated highly to accept the weld and that this then created a weak spot on each side of the weld :headbang: creating two weak points versus the one fixed. Anyway personal preference was to get 4 alloys of the same style to replace the cracked one and two rear kerbed ones giving me 3 spares. This option worked for me.

Nor is it a MOT fail so done correctly i see a weld on a wheel no worse than a weld anywhere else on the car no matter what bhp it has :wink:

Rob ... I was joking. Sarcastically, but joking nonetheless.

That said, I've never driven a car with welded wheels and I never shall, least of all a powerful one. (Now that's not a joke. Not at all.)

The final finished colour is more of a silver grey than the original bright silver - still deciding if we like the new colour or prefer the original

Car looks high on the front suspension, would like to lower the front but don't want to mess up the handling etc.
