NP Pro Top mounts

Pro Top Mounts – Adjustable CNC Aluminium Suspension Top Mounts

The Pro Top mounts are a pair of fully adjustable motorsport-grade suspension top mounts manufactured by NP Parts, combining CNC-machined 6082-T6 aluminium mounting components with an ultra-lightweight 7075-T6 aluminium bearing housing weighing just 55 grams. Designed primarily for BMW platforms, they are equally applicable to any custom motorsport or race car build that requires a welded top mount solution with full three-axis adjustment capability.

Sold as a set of two, the Pro Top mounts allow independent adjustment of caster, camber, and rotation, providing the setup flexibility that serious suspension tuning demands. Standard anodizing is black, with custom colors available on request with a two-week lead time.

Key Features & Benefits

• 6082-T6 CNC-machined mounting parts – the primary mounting structure is machined from high-strength 6082-T6 aluminium, providing a rigid and durable base for the adjustable geometry system.
• 7075-T6 aluminium bearing housing, 55 g – the bearing housing is machined from 7075-T6 aircraft-grade aluminium and weighs only 55 grams, delivering exceptional strength-to-weight performance in a highly loaded component.
• Full three-axis adjustment – caster, camber, and rotation – all three primary suspension geometry parameters can be adjusted independently, providing the setup range required for competition suspension tuning.
• Extremely lightweight setup – the combination of 7075 bearing housing and CNC-machined components keeps total assembly weight to a minimum, reducing unsprung mass and improving dynamic response.
• Compatible with BMW and custom race car builds – designed for BMW platforms but applicable to any race car where a welded top mount solution is required, making them suitable for custom and single-make builds alike.
• Black anodized standard finish – the standard black anodized surface is durable and resistant to the operating environment of a competition strut tower.
• Custom anodizing available – other anodized colors can be specified at order, with a lead time of approximately two weeks.
• Sold as a set of two – price covers a complete front axle set for a full vehicle installation.

Materials & Construction

• 6082-T6 aluminium billet – used for the main mounting parts, offering high yield strength and good corrosion resistance in competition conditions.
• 7075-T6 aluminium (55 g) – aircraft-grade aluminium used for the bearing housing, providing maximum strength at minimum weight.
• CNC-machined precision parts – all components are machined to precise tolerances to ensure consistent geometry adjustment and secure installation.
• Anodized finish – black standard; custom colors available on request.

Applications

• BMW motorsport and circuit builds – the primary platform for which the Pro Top mounts are designed, supporting setup changes at competition events.
• Custom race car fabrication – where a welded, adjustable top mount solution is required in a bespoke suspension design.
• Time attack and hillclimb – where fine suspension geometry control directly translates to lap time performance.
• Endurance and sprint circuit racing – where top mount geometry may need to be adjusted between sessions or events to optimise handling balance.
• Rally and stage racing – where the ability to modify suspension geometry rapidly between stages is an operational advantage.

Why These Pro Top Mounts Are Important

Top mounts are a critical and often underestimated component in the suspension geometry setup of a competition car. The strut top mount defines the upper pivot point of the suspension assembly; any variation in its geometry directly affects camber, caster, and the steering axis inclination. The Pro Top mounts replace standard rubber-mounted, non-adjustable OEM components with a precision, fully adjustable aluminium assembly that allows the setup engineer to dial in the exact geometry required for the track or event conditions. The ultra-lightweight 7075-T6 bearing housing further reduces unsprung and reciprocating mass compared to heavier production mounts, contributing to improved suspension response.
