M135i (LCI) best wheel offset?

Post by LondonMark » Thu Jan 04, 2018 1:51 pm

Hi everyone, I have a question! :? :?

I've seen all the great photos of your cars with the 20/25mm Motech springs, and the 12/15mm spacers. I want to get this look too, but the insurance hike for adding the spacers is +£130, (the springs not so much extra), so I've decided to buy new wheels with an offset that will give me the same look I would get by adding wheel spacers. After looking at tons of wheels, the ones I like the best have a fitment of: Front 8J ET38, Rear 9J ET42. Using an offset calculator, based on the OEM wheels, the new fronts extend and extra 13mm, and the new rears extend and extra 23mm.

Does anyone know if:
1,These will fit ok without any problem?
2, if they do, will they give the look/stance that I'm after?

Cheers :D

Mark,

You could consider OE F3x alloys which are wider and have lower numerical offsets give more stance, compared to OE F2x alloys.

They will fit, and have the extremely stanced/aggressive look you're after.

From an engineering perspective spacers are the work of Satan.

Thank you all for your replies, they're all very helpful. :spotman:

Blind Pugh - The 397's look great, but the new price is out of my budget, and even used on Ebay are quite pricey, plus I'm a bit unsure about buying used wheels.

Cheers, Mark :P

Can someone please explain why it’s better to run wheels with a lower offset rather than equivalent spacers? :)

"Better" is not the word. "Less worse" is more accurate. Specifically to your question. If you really, really must change the offset, different wheels gives one less clamping surface for torque to be transmitted via the wheels to the road.
Remember that the bolts do not transmit torque, they merely hold two surfaces together.

Agreed.

Wheels with silly offsets still muck up the scrub radius, so I wouldn't fit front wheels like that personally. It's not so much of an issue on the rear, from a Geo point of view.

I have set that came off my car 8"/8.5" in ferric grey - used but in good condition no dents/buckles or repairs. Provided yr budget is realistic, perhaps PM me an offer ???

As you are London based too, suggest you come and have look 1st hand.

So are we saying, for example, running wheels with 10mm lower offset or running a 10mm spacer would have an identical effect on scrub radius and the associated handling characteristics?

Does introducing another clamping surface create a weak link, as such?

Just trying to understand why spacers are frowned upon, thanks :)

Check with yr insurer - cost of changing wheels v cost of adding spacers to yr OEM wheels......
