Complete rear toe kit for the BMW E9x M3: two fully adjustable toe arms. Billet AL-7050-T7452 with 17-4PH stainless spacers and PTFE-lined spherical bearings. Optional lockout plates. Competition use.
A pair of fully adjustable E9x M3 rear toe arms that replace the compliant factory toe links. Set your rear toe on the rack and it holds under load and braking instead of wandering. Engineered in-house by Meisterschaft Motorsport.
A suspension arm fails three ways: the body cracks, the misalignment spacers gall and pound out, or the bearing wears. We chose our materials to beat all three.
An overaged aerospace 7000-series alloy for thick, highly-loaded structure. Excellent fatigue life and stress-corrosion resistance.
The misalignment spacers and studs that carry the bearing load are precipitation-hardened stainless: hard, strong, corrosion-resistant through the part.
Zinc-plated chromoly body, hard-chrome ball, PTFE-lined race. The proven spherical architecture, zero deflection.
Why these materials? We published the full engineering rationale — alloy yield comparisons, spacer hardness, bearing architecture and the two anodize types — in Why Our Materials & Our Finishes.
The development and mileage-accumulation programme ran on our Toyota A90 Supra: roughly 40,000 miles of accumulated durability and track use over about two years, with the rod ends run bare, with no boots or seals, exposed to year-round South Florida heat, humidity, rain and grime, plus repeated track abuse. The hardware came through intact, with no failures.
Track-tested at Sebring International Raceway on racing slicks, one of the most punishing circuits on earth, its bumpy airfield concrete notorious for shaking cars apart.
That programme is what validates the parts that actually wear: the PTFE-lined spherical rod ends, the AL-7050-T7452 arm bodies, and the 17-4PH stainless misalignment spacers and studs. Every Meisterschaft arm is built around that same rod-end architecture and the same three materials, whatever the chassis, so the durability demonstrated on the A90 programme carries across the range, including these E9x M3 rear toe arms.
Every arm is anodized, and we offer two finishes. Both are structurally identical — the difference is how the surface is prepared, how it wears, and how it looks.
A thinner, decorative anodize over a polished surface, giving a bright, clean silver-gray that shows off the machining. It is the sharper-looking finish of the two, but the thinner layer marks more readily anywhere a wrench touches it, so it stays looking its best on a build that gets set once.
Glass-bead blasted first to lay down an even matte surface, then hard-coat anodized. The hard-coat process grows the surface itself into a thick aluminum-oxide layer, a ceramic far harder than the base metal, so the threads, jam-nut flats and wear faces resist galling, wrench marks and abrasion. (Hard anodic coatings are commonly rated around 60–70 HRC equivalent, converted from microhardness — a thin ceramic layer over aluminum cannot be measured directly on the Rockwell C scale.) The result is a deep satin graphite gray that still looks right after years of setup changes.
Pick your coating right above the Add to Cart button. Both finishes carry the same structural warranty — the difference is wear resistance and appearance over time, not strength.
| Kit contents | 2× rear toe arms, left + right (not sold separately) |
| Arm type | Rear toe, fully adjustable |
| Arm body | Billet AL-7050-T7452 |
| Spacers / studs | 17-4PH stainless (H900) |
| Rod ends | M14 · PTFE-lined 3-piece spherical |
| Jam-nut flats | 22 mm hex; the arm body also accepts an 18 mm wrench |
| Optional | Toe lockout plates (+$100); 304 stainless plates, grade 10.9 Geomet hardware |
| Sold as | Complete pair; not sold separately |
The jam-nut flats are a 22 mm hex, and the arm body has a design feature so a single 18 mm wrench works too. No need for two 22 mm wrenches to lock your setting.
Running a lot of rear toe, or want your setting to survive curbing and contact without walking? Add our toe lockout plates. They positively clamp the factory eccentric at the chassis mount so the toe setting is held mechanically, not just by the pinch of the eccentric bolt.
The plates are machined from 304 stainless steel, not aluminum, so they will not gall or crush at the clamp. The add-on ships with grade 10.9, Geomet zinc-flake-coated hardware, the same grade and coating the factory uses on structural bolts. Add them below for $100.

Off-road and competition use only. These motorsport components are designed, manufactured, and sold exclusively for off-road, competition, track, and closed-course use. They are not designed or intended for use on public roads or highways and are not street legal. Any use on a public road is undertaken entirely at the user’s own risk, voids this warranty as to the affected parts, and Meisterschaft Motorsport Engineering LLC accepts no liability for it. It is the buyer’s sole responsibility to confirm the product is suitable and legal for the intended use.
Warranty. Limited Lifetime warranty on the structural components (arm bodies and 17-4PH stainless spacers and studs) for the original owner, against defects in materials and workmanship. Two years on the spherical bearings and other wear items, provided the parts were installed by a professional technician, or by an individual with the proper tools and competence, strictly following our published installation instructions.
These are adjustable, load-bearing suspension components. They must be installed, torqued to specification, and aligned by a competent professional after fitment. Improper installation is the most common cause of premature bearing wear and hardware failure, so this warranty does not cover damage caused by incorrect installation, incorrect torque, installation not performed to our specifications, modification, misuse, or crash, curb, or impact damage. It is the owner’s responsibility to have the parts installed and set up correctly. A dated receipt or order number is required for any warranty claim, and an alignment and an inspection of the installation by a qualified shop after fitment is a condition of coverage. The full warranty text is at meisterschaftmotorsport.com/warranty/ – please read it before purchase.
If you crash on track, the original purchaser can request replacement arms at 15% off the current published regular price – see the crash-replacement program. On-track incidents only.
Anodizing grades referenced above follow the US military specification MIL-PRF-8625 (formerly MIL-A-8625), Type II and Type III, for anodic coatings on aluminum.
