TE37 Ultra M-Spec BMW F80/F82: 20x10 +30 & 20x11 +32 Guide
Looking at a genuine 20-inch RAYS Volk Racing TE37 Ultra M-Spec package for a BMW F80 M3 or F82 M4? This guide examines the exact front 20x10 +30 / rear 20x11 +32, 5x120 configuration listed by HausofWheels. It explains the staggered widths, the key clearance questions and the differences between a 20-inch street build and other wheel setups.
Fitment warning: The M3/M4-spec label is a useful starting point, not proof of fitment for every F80/F82. Tyres, brakes, ride height and hardware can change the result. HausofWheels supplies wheels only and does not provide installation or test fitting.
20x10 +30 and 20x11 +32: specification breakdown
| Position | Wheel size | Offset | PCD |
|---|---|---|---|
| Front | 20 × 10 inches | +30 mm | 5x120 |
| Rear | 20 × 11 inches | +32 mm | 5x120 |
Both wheels share the 20-inch diameter, but the rear wheel is one inch wider. A higher or lower numerical offset does not tell the full story without the wheel width. When comparing this package with the original BMW wheels, work out inner and outer positions for each axle and account for your tyre dimensions.

What is a TE37 Ultra M-Spec wheel?
RAYS identifies the TE37 Ultra M-Spec as a forged one-piece Volk Racing wheel in its 19- and 20-inch lineup. The classic six-spoke TE37 design is developed for performance applications. The wheel's construction is distinct from one-piece flow-formed wheels: do not describe the Ultra M-Spec as a flow-formed model.
RAYS also documents optional centre caps and vehicle-specific parts. Confirm which accessories come with your particular set; the general manufacturer's accessory table does not mean every cap or wheel bolt is included in the retailer's package.

Why 20-inch staggered fitment needs extra checking
A wide, staggered 20-inch setup can suit an appearance-led street build, but there are several things to verify before choosing tyres or arranging pickup:
- Front brake clearance: Confirm both the spoke-to-caliper and inner barrel clearances against the exact front brake package. A 20-inch diameter by itself does not prove clearance.
- Rear guard and suspension: Review the 20x11 +32 rear position with your intended tyre, camber and ride height, particularly if the suspension has been lowered.
- Tyre width and overall diameter: Check approved tyre-to-rim combinations and rolling dimensions rather than choosing a tyre solely from how it looks in photos.
- Staggered rotation limitations: Different front/rear widths typically prevent ordinary front-to-rear tyre rotation.
- Centre bore and bolts: Confirm the actual wheel's hub bore, BMW hub interface, bolt-seat style and any approved installation hardware. Matching 5x120 alone is insufficient.
20-inch TE37 Ultra M-Spec versus 19-inch wheel options
Both diameters can make sense on an F80 or F82, but they prioritise different characteristics:
- 20-inch: A larger visual footprint and often a lower-profile tyre. Availability of a suitable tyre and adequate guard/ride clearance must be planned.
- 19-inch: An alternative balance of tyre sidewall, comfort and performance. Different rim widths and brake packages still need independent clearance checks.
- Brake choice matters more than diameter alone: Larger or carbon-ceramic brake packages can create particular barrel and spoke-clearance requirements. Confirm using the exact wheel face and manufacturer/brake measurements rather than assuming any size is universally safe.
For a general comparison of F80/F82 wheel sizes, refer to our existing BMW M3/M4 fitment guide. The purpose of this article is to evaluate the exact 20x10 / 20x11 Ultra M-Spec setup without duplicating that broader guide.
What should I provide when requesting a fitment check?
- BMW chassis and model year: F80 M3 or F82 M4.
- Original or modified suspension, current ride height and camber.
- Standard steel or optional carbon-ceramic brakes, plus any non-factory brake modifications.
- Current front and rear wheel/tyre sizes, spacers and any rubbing issues.
- Proposed tyre brand/size for the 20x10 and 20x11 wheels, plus how you use the car.
The HausofWheels Fitment Finder can help organise these details. You can also send a specific enquiry before ordering.
Frequently asked questions
Are 20x10 +30 and 20x11 +32 square wheels?
No. They form a staggered package because the front and rear widths differ.
Does 5x120 mean these fit any BMW?
No. PCD is only one parameter. Hub bore, brake clearance, width, offset, hardware, tyres and guard clearance still matter.
Will these clear F80/F82 carbon-ceramic brakes?
Do not assume clearance. Verify the precise brake kit, wheel face and barrel clearance before ordering.
Are centre caps included?
Check the particular product listing or ask for confirmation. General RAYS catalogues identify compatible accessories, but supplied parts can vary.
Does HausofWheels fit tyres or test-fit wheels?
No. We supply genuine wheels only. Hurstville pickup is available by confirmed appointment and Australia-wide shipping is offered.
