Turner Motorsport BMW E46 M3 Front Adjustable Camber/Caster Plates Top Mounts – Street Polyurethane Strut Mounts – Alignment Caster Camber Kit, Fast Road/Track, OE & Coilover Compatible

Turner Motorsport adjustable front top mounts for BMW E46 M3

Unlock sharper turn in, flatter cornering and consistent tyre wear with these Turner adjustable front upper mounts for the E46 M3. Built with a genuine motorsport pedigree yet refined for fast-road use, this alignment upgrade gives you precise caster and camber control without sacrificing daily comfort thanks to the compliant urethane isolator.

Perfect for anyone chasing an E46 M3 handling upgrade, track day setup or fast-road geometry, these mounts offer easy, independent adjustment so you can dial in extra negative camber and caster advance for grip, stability and steering feel. We run these on our own builds and our customers love the transformation.

Why enthusiasts choose these adjustable strut mounts

• E46 M3 specific design that keeps the correct suspension kinematics and motion ratios
• Independent sliders for camber and caster so you can fine tune alignment precisely
• Road-friendly urethane insert to reduce harshness and vibration compared with solid race mounts
• Low stack height that preserves maximum damper travel for ride quality and performance
• Large footprint top plate that spreads load to help resist strut tower mushrooming
• Lightweight construction with robust materials for long-term durability
• Simple, bolt-on installation with clear markings for repeatable setup

E46 M3 fitment that just works

Turner engineered the bearing location and angles specifically for the E46 M3 MacPherson strut, minimising side loading on the damper shaft and reducing bending forces. That means better performance and increased longevity from your shocks.

OE compatibility and spring options

• Retains the factory radial bearing and spring perch so the spring rotates freely instead of binding
• Lower assembled height when using the OE radial bearing for more usable shock stroke
• Use with standard diameter springs, 60 mm, or 2.5 inch coilover springs
• When using stock-sized springs, reuse the OE perch and bearing. 60 mm and 2.5 inch upper perches are available separately

Damper compatibility

Designed for 16 mm strut shafts with the correct bearing size, so no sleeves or adapters are required. Compatible with OE-style struts and leading performance dampers including Sachs or Boge, Bilstein, Koni, H&R, ST and KW that accept the factory mount pattern.

Benefits you will feel

• Increased front-end grip and confidence on B-roads and circuits
• Improved steering precision and stability under braking
• Better tyre contact patch management for reduced outer shoulder wear
• Repeatable, track-day-friendly alignment changes
