With the release of the new G90 and G99 M5, we wanted to reduce the amount of guess work and time researching to see what spacer sizing is recommended, so we went ahead and tested all the options for you with our latest G90 M5 spacer prototypes.

As we've done for each new M car release, but also considering the confusion and early misinformation regarding the new M5's wheel specs, we set out to create a comprehensive resource for new G90/G99 M5 owners looking for spacer and wheel fitment.

G9X M5 Bolt Pattern and Style 951M Wheel Specs

• 5x132mm PCD
• 66.56mm Centerbore
• M14x1.25 2-Piece Floating Lug Bolts
• Front Wheels: 20x10.5 et28
  • Tire Size: 285/40R20
• Rear Wheels: 21x11 et28
  • Tire Size: 295/35R21

No Spacers / OE Suspension:









With BMW introducing a brand-new bolt pattern for the G90 M5, IND immediately contacted our longtime partner Fall-Line to get to work on a bespoke spacer designed specifically for the G9X platform and potential future models. Our collaboration ensures that this spacer is engineered to the highest standards, considering both performance and compatibility.

Additionally, the same renowned characteristics found in the FC spacers—such as precision machined pocketing, hub-centric design, and secure hub-mounting provisions—will carry over into the G9X M5 spacer to maintain the level of excellence you expect.

FC 5x132 Wheel Spacers by Fall-Line (Made in USA) COMING SOON

• Complete kit includes: two competition wheel spacers, ten extended length zinc plated lug bolts, four hub bolts, Copaslip copper anti-seize, and an anti-seize applicator brush
• CNC precision machined from 6061-T6 aerospace aluminum based on 3D CAD data
• Black anodized finish for corrosion and wear resistance
• Only spacer on the market with provisions to secure the spacer to the hub
• Hub-centric design with chamfered edges
• Larger diameter spacer pad matching OE hub and wheel mounting face specs
• Pocketed detailing for minimum weight/rotating mass

IND's Recommended Spacer Sizing

• OE Ride-Height, Wheels, and Alignment - 12mm Front / 12mm Rear | Effective Wheel Offset:
  • Front 20x10.5 et16
  • Rear 21x11 et16
• Lowered Ride-Height with OE Wheels and Alignment - 12mm Front / 12mm Rear | Same Effective Wheel Offset as above
• Lowered Ride-Height with Square 21x11 OE Wheels and Alignment - 5mm Front / 12mm Rear | Effective Wheel Offset:
  • Front 21x11 et23
  • Rear 21x11 et16

Recommended Fitment / OE Suspension: 12mm F / 12mm R









Spacers are similar to aftermarket wheels with regard to opinions; everyone has different preferences and tolerances. At IND, our goal is to achieve a wheel and tire fitment that is flush to the edge of the fender with minimal poke which we feel is best achieved with 12mm spacers front and rear. However, for the G90, it may also be helpful to factor in the type of tires your vehicle came equipped with when trying to achieve a specific look, though the difference is slight.

Vehicles delivered with:

• Hankook tires may appear to have a slightly more rim-edge "poke" due to a more pronounced built-in rim protector, but a much more rounded sidewall with narrower tread.
• Michelins should see a slightly fuller look due to the more squared shoulders and marginally wider tread block.
• Pirelli tires have a similar profile to the Hankooks, but have a slightly smaller section width so may fall somewhere in between.

The IND G90 M5 came with Hankook tires from the factory.

12mm Front and Rear:

Update 1/29: Apologies for the delay, a lot of projects going on. We are very grateful to AST / MOTON for providing us with a set of prototype lowering springs for our G90 M5. Since this is a prototype set, we're not going to comment on the ride or handling in the event that they tweak the final spring rates, but the overall lowering should remain pretty much the same on the production spring set:
1.25" front drop
1.125" rear drop

With BMW's "double wishbone" front suspension on the M5, you're able to keep the factory alignment specs when lowering, so our recommendation for spacers is going to remain the same at 12mm Fr / 12mm Rr when lowered. On the smaller models with MacPherson style front struts, lowering generally results in a bit more front camber, so you typically want to move to a slightly larger spacer to keep the same fender-fitment.

Recommended Fitment / AST Lowering Springs: 12mm F / 12mm R










And obviously with all the interest in running the square rear setup (21x11 et28 with 295/35R21), we also installed with and without spacers. A 12mm spacer in the rear is still ideal and while you can get away without a spacer up front, adding a 5mm spacer will retain the flush fitment.

Recommended Fitment / AST Lowering Springs / Square 21x11 et28: 5mm F / 12mm R










And for good measure we also included running the square rear wheel fitment with no spacers.

Great info. When do you anticipate the 12MM will be ready for purchase and delivery?

If all goes as planned, we should have spacers ready to distribute & ship next month.

[soulsea]

Amazing info. Thank you so much for doing the research and for making the information public.

It looks like the sweet spot in order not to go past flush would be 15 front 12 rear, but I wonder if that difference is enough to confuse the ECU's AWD calculations to throw a code.

If you think it won't then that's what I'll order, otherwise if we need to be symmetrical then I'll do 12 all around.

Thanks again.

Staggered setup should not be an issue at all. The G80 also featured xDrive's and this was not an issue on this M-specific chassis.

We have springs going on the car as we speak to test that idea of 15 F / 12 R. Once lowered, we think this might be the best setup; time will tell.

Amazing post! Thank you IND-Distribution

As I’m looking at the pictures, I keep asking myself why would BMW decide to ruin the visual appeal of the car with such tall front wheel sidewalls. They’re literally taller than on my X5 M60i stock 21” winter wheels…

Hence the question what chances do you see for options to fit 21” wheels upfront? Could the car be run on a square 295/35/21 set of tires?

The overall diameter and circumference of the front (285/40-20) and rear (295/35/21) tires is virtually identical (less than 0.5% difference to keep xDrive happy) so there's no issue running the rear size all around with regard to the drivetrain. However, we haven't yet tested one of the rear wheels on the front to confirm clearance when turning or the inner clearance to the upright with the slightly wider wheel.

Since the wheels are the same offset and only 1/2" wider out back, that means they'll only lessen inner upright clearance and outer fender clearance by 1/4" vs the OE front 20x10.5's. Considering the 12mm front spacer is wider than 1/4", the fender clearance isn't an issue, so we'd just need to check strut-side clearance and liner clearance when turning.

Not sure how i missed you taking delivery of this vehicle but looks great. I ordered same colour for my G99 but with orange interior. Hope you have started on mods for that. Cant wait to see.

We'll have more photos to share soon, but we did want to confirm that running the rear 21x11 Style 951M's with 295/35's all around fits just fine and has roughly the "equivalent appearance" of running a 6mm spacer on the 10.5" fronts (in addition to being a 21" vs a 20" wheel).

We'll have more information to share on our recently installed AST lowering springs. The G90 really looks good lowered with 21x11's all around.

This is exactly what I wanted to hear. I will probably order 2 extra rear wheels. Someone might want my 20” front wheels to use for a winter set.

Also, in a pinch I could throw one of the “extra” fronts on if I have a flat and can’t get a tire quickly.

I was thinking of doing the same thing.

Great post IND, really helpfull .. keep us posted about the lowering springs and share as much setups as possible

You guys are doing a great job for the G90!

[Skilly]

great post - any group buy or pre-pay we can do to get the first release? The cars are finally being released for selling in the US; picking mine up today!

Also very interested in the lowering springs set up too!

Lowering spring media is soon to come! The drop on the AST springs is nothing short of amazing!!

We will announce when orders for the FC spacers are live, but we are not accepting pre-orders, and group buys will not be applicable.

Unfortunately, 10mm spacers will not be an option. While some vendors do offer 10mm spacers for 5x112 bolt pattern vehicles, the issue lies in machining a hub-centric flange into the spacer. The transition from the factory hub can create a structural weak point in the spacer disc, increasing the risk of failure.
BimmerWorld is currently the only vendor that has successfully engineered a 10mm spacer for 5x112 vehicles, to our knowledge. They achieved this by utilizing the scalloped hub design found on certain G-Chassis vehicles.
However, with the G90 M5's switch to a 5x132 bolt pattern and a standard, non-scalloped hub, this approach isn’t possible for the new platform.

Here’s a helpful video from BimmerWorld explaining the unique challenges and their 10mm spacer solution:

do you carry H&R - looks like they have a sport spring available

We do carry H&R, but have not launched the G90 spring option as right now availability is still looking like a summer release so unless that changes, offering the product may be a bit premature.

We are working as quickly as possible to bring the G9X M5 spacers to market.
