Product Description
This staggered set of BimmerWorld wheels for the E46 M3 and Z4 M is a direct fit with no fitment hassle or interference issues. Front wheels are 18x9.0" ET42 and rear wheels are 18x10.0" ET25. These are only moderately larger than the stock E46 M3 wheels with a generous size in the front to help reduce understeer. Sizes and offsets have been carefully chosen to give the best fitment within the stock bodywork - no rubbing on fender or suspension*. These are true lightweight forged wheels at a great price for the set!Our TE:AL (Technical Alloy) alloy wheel is constructed as a true forged piece, not "semi-forged" or "flow-forged". A fully forged wheel is stronger and lighter than cast wheels (a semi-forged wheel is still cast). Through careful design using CAD and FEA we were able to trim material to make a lighter wheel without sacrificing strength. The 16 spokes and barrel design leave generous room for big brakes. We also incorporated several unique features normally found on high-end race wheels - knurled bead seat to minimize the wheel spinning inside the tire and a reverse-mount feature that makes it easier to mount tires from the backside of the wheel. Because these are our own proprietary wheel, we're able to offer them at roughly half the cost of other forged race wheels in the BMW market!
Key Features:
- Ridged cross-spoke design and internal outer-barrel strengthening rib for ultimate strength, rigidity/camber stiffness, and durability
- Massive Caliper Clearance - 18" versions fit up to 380mm brakes
- Pocketed center pad to minimize weight without compromising strength
- Machined from T6061 aluminum forgings, produced with an industry-leading 10,000 ton press for optimized grain flow
- Shot peened and heat treated for exacting strength and increased durability
- Gloss finish is easy to clean
- Knurled bead seat to minimize tire slippage with higher-powered cars and under heavy braking
- Accepts BMW factory center cap (not included)
- Optimal tire sizes: F: 255/40-18, R: 275/35-18
- Reverse mount
* Note: we have carefully chosen these sizes and offsets because they have worked for us in the past. However, we cannot verify fitment with every combination of wheel-tire-suspension setup. Verification of wheel fitment is the responsibility of the customer. These wheels, like many wheels, are not compatible with 10mm wheel spacers. We recommend using 12mm spacers, as 10mm hubcentric spacers have inherent design limitations that prevent them from sitting flush. Please contact us directly if you have any questions or concerns. Returns are limited to quality issues only.
