Materials
- Arm bodies: billet AL-7050-T7452 aerospace aluminum, about 69 ksi yield (roughly 1.7× the 6061/6082-T6 used by most aftermarket arms), with high fatigue life and stress-corrosion resistance.
- Misalignment spacers and studs: 17-4PH H900 stainless, about 170 ksi and 40–44 HRC, roughly four times harder than aluminum spacers, so they do not gall or brinell.
- Rod ends: M14 three-piece spherical bearings with a zinc-plated chromoly body, hard-chrome ball and PTFE-lined race. No slop, and replaceable when worn.
- Engineering: designed and FEA validated in-house by Meisterschaft Motorsport Engineering.
Tested
Developed on Meisterschaft's own A90 Supra over roughly 40,000 miles and about two years of street and track use, including Sebring on slicks, with the rod ends run bare (no boots) in South Florida weather. No failures. Every Meisterschaft arm uses the same rod ends and materials.
Complete the rear axle: pair these with the Meisterschaft rear toe arms for the E9x M3.
Coating options
- Type III hard-coat anodized, satin graphite (recommended): glass-bead blasted, then hard anodized (MIL-PRF-8625 Type III). The thick ceramic oxide layer resists galling, wrench marks and wear on the threads and flats. Best if you adjust your setup often.
- Type II standard anodized, polished bright ($80 less): thinner decorative anodize (MIL-PRF-8625 Type II) over a polished surface, bright silver-gray. Marks more easily where tools touch it. Best if you set the arms once and leave them.
Both finishes are structurally identical and carry the same warranty.
Intended use and warranty
For off-road, competition and closed-course use only; not street legal. These are adjustable, load-bearing suspension parts: have them installed, torqued to spec and aligned by a qualified professional. Meisterschaft covers the structural parts (arm bodies, stainless spacers and studs) with a limited lifetime warranty for the original owner and the spherical bearings and wear items for two years, subject to correct installation and a post-install alignment and inspection. Crash damage is not covered; Meisterschaft also runs a discounted crash-replacement program for on-track incidents, so ask us for details. Full terms: meisterschaftmotorsport.com/warranty.
Made to order. Leg Down Racing will confirm lead time with you after you order.
