So I'm thinking I might get me some new wheels:
I'd never really considered anything other than 19", but I see so many 35s & M cars on 20"s while surfing t'internet, I'm wondering if I should consider them.

What do you guys think? Would a good lightweight set of 20" with mpss be a good performer on the 35D?

Muchas gracias amigos!

I'd love a set of 20" 405Ms, and I do wonder if with being forged and 3kg a wheel lighter than 403/442 wheels then this may help offset the reduction in sidewall.
But it's an estate car and a daily driver, and our roads are appalling, and so the sensible streak in me wins out.

I absolutely wouldn't want to do it on runflats, would have to be MPSS for me.

i can tell you 1 thing. a good *lightweight* set of 20s, aftermarket, all in. will set you back 3 or 4 grand at the very least. im one of those weirdos who stays well away from used wheels, im sure theres some good ones out there however

looks fantastic though. even more fantastic on those schnitzer rs suspension kit things some are going for

I run 405's on my f36 with the Pirelli rfts at the moment - with adaptive not massively different to 19's. When the tyres are done I will be going mpss!

That said was in the local stealer today and they had a Ferrari red M3 shod with contis!!!

[teaston]

With the F3x sidewalls (except F34) I think 19's are the sweet spot for handling and comfort on British roads. Also I wouldn't want those little rubber bands on the 20's being all that protects my £3k set of wheels from damage!

[Lorcan]

I would stick with 19s on a 3 series but the bigger-bodied 4 series carries 20s really well. I'd almost say it "needs" them to look right. Almost

We offer staggered 19s (8.5J front, 9.5J rear) at £3000 or 20s (8.5J front and back with wider tyres) at £3255 with MPSS fitted.

[Lorcan]

By the way, I've driven this car on these 20s, MPSS and our springs and it was comfy - not harsh at all.

Hi Lorcan

What's the weight saving per wheel (19s, no tyres), and are they forged ?

Cheers

[Lorcan]

The ones pictured above aren't forged - our forged wheels are £5k without tyres! I can find out weights of these, but the saving will depend on which BMW wheels you are comparing them to.

[Richtw]

Should have said they are also running on ACS springs from Lorcan - I mean why would you not want them, lower, stiffer and some how comfier

An obvious miss on my part; compared to 403s.

[ajfoggy]

I have the 20 624s on mine with the ACS Springs.

Again not harsh at all.

I was thinking mpss are a little chunkier so would offer slightly better protection than say the contisport?

oooh see now that looks good!

What I don't want to do is spend a hefty sum and end up unhappy with either looks or ride, so it's a tough choice.

I have Kev Bird's suspension setup so it's already lowered with better springs/dampers, so that side of things is sorted. But as you say, the 4 is a big car and certain 19"s just look a bit small on it I think.

[Lorcan]

The way AC Schnitzer cars sit is partly due to the suspension and partly due to the offset of the wheels which, to an extent, is something people try to mimic using spacers on standard wheels. Schnitzer wheels often have a more aggressive offset than BMW or Alpina wheels for example, which are usually tucked inside the wheel arch more.

More fours on 20s:

What tyre sizes are you running on those 20"s Lorcan?

Do you think there's any issue with getting the power down or handling with less sidewall?

Buying 20" replicas of a wheel like the 405M which has a spindly, delicate design, and low tyre sidewall is asking for trouble IMO. They'll also be heavier.

To be honest I don't know of any replica 405m sellers off hand but have heard a few stories of people with replica 405m's breaking because they're weren't forged alloys, possibly the Chinese replicas. I know the alloys are expensive but have you tried Cotswold Bmw for a price on the 405m's. They do some good deals on m performance parts.
Sorry can't help you much.

Hookjaw,

We're running similar set ups with the Birds suspension and I'd say 20" is the only way to go on the 4 series it's the first thing everyone comments on when they ask about my car. I'm running 285x25 on the rears and 245x30 on the front, ride wise it's only a problem on roads with pot holes ( which is just about every bloody one up here in the NE at the moment!) wheel design is of course your own preference.
