You're very welcome! I've realised some of the alloy wheel sizes I've mentioned aren't right, I think the 17's all came as 8J not 7J... but I'm going to gather some more bits together before I proceed with a full update! Glad it could be of help :)

C8H18 wrote: Wed Jul 25, 2018 10:25 pm Apologies - I wasn't talking about high performance cars being fitted with spacers, but the performance benefit from increased track. Performance cars don't come with spacers from the factory as the suspension is already configured to perform optimally without them. However, they will likely strive to increase track as much as reasonably practicable due to the performance benefits of doing so.

Would a slight increase in track (from fitting spacers) offer a noticeable performance benefit? Unlikely. There are also downsides, such as increased loads on wheel bearings. I wouldn't use them except to correct a different wheel offset back to OE spec.

I'm probably sounding like a total pedant now. That wasn't my intention - your post was really informative. However, it may be of interest to some people. Equally, if you or the mods think it's an unnecessary distraction on this thread, then I have no objections to the posts being removed. This bloke explains it all much better than I could...

Not at all. It's all in the interest of sharing info and experiences. It's useful to know it could have some performance benefits, even if they're minute. Something for people to pursue in depth for themselves if they want/need. In terms of the thread I'll leave it as is for now... unless theres suddenly a lot of research done (specifically for the car) that categorically states positive/negative implications of their use. After all we're talking Zed specific and not generally... and so 10mm and 20mm spacers would be negligible differences in the grand scheme of things IMO :thumbsup:

Great thread and lots of really useful information. Can I ask if anyone has ever done a weight comparison for the standard wheels? Might be interesting and useful for a few people, like me! ;-

Cheers fella.

Info is out there, just needs to be compiled by someone :poke:

For what it’s worth I’m sure Style 32 are the lightest (or one of the lightest) wheels out there for e46/e85 cars... maybe worth looking into? :)

For some reason its just the 18s style 32 , the 17s weigh just like any other 17s , the staggered 18s however are noticeably lighter than any other oe Bmw wheel ive ever come across , no idea why that is :cry:
I would have expected the gen CSLs to be similarly lightweight but reality is not the case :?

Very useful compilation, I'm looking for a set of 107's as my 108's are in need of a refurb and tyres are getting low so a good time to be looking, anyone got a spare set of 107's?

Best bet is posting a “wanted” thread in the buy and sell. Maximise on potential members looking to offload. Good luck fella :thumbsup:

Another wheel to add to your list - style 241 star spokes

On spacers, I’ve tried a mix of 15mm and 20mm spacers on front and rear. Have ended up with 15mm all round. If I had 245 section tyres on the rear I might go 20mm but it sticks out a bit too much with 255s.

I have found that adding spacers has definitely reduced twitching/tram lining of the steering. Car does feel noticeably better with the added benefit of better aesthetics.

I’ve had the front camber pins pulled and maxed front camber. It does make a noticeable difference to front end grip. Also running slight toe out at the front to make it a bit more lively. Think it could do with a bit less rear toe in (currently inside oem spec, just). I’m toying with running a square set up on 405m forged 18” wheels (currently my 330d winter tyre wheels) so that might get me the additional rear adjustment one looking for.

Hi
I’m new to the forum, wonder if you can help with a query on tyres for standard 16” wheels (style 104 I think).
Can I fit wider tyres to the 16” wheels? If so, what width/profile can I comfortably go up to?

Thanks for your help
Lawman
