Overview
The factory front strut top hats on the B9 platform rely on rubber bushings to manage strut movement and absorb road inputs. Under spirited driving, track use, or even aggressive street conditions, those rubber bushings deflect, degrade, and introduce compliance exactly where you want none — corrupting steering feedback, blurring turn-in response, and allowing strut geometry to wander under load. On modified B9 chassis running lowering springs or coilovers, the problem compounds further: increased spring rates accelerate rubber fatigue and amplify the vagueness already built into the OEM design.
TGK Motorsport engineered these Spherical Front Strut Top Hats to eliminate that compliance entirely. Machined from 6061 billet aluminum and fitted with Teflon-lined spherical bearings, they replace the rubber bushing interface with a zero-deflection pivot point — delivering immediate, accurate strut movement that translates directly into sharper steering response, consistent camber retention, and predictable chassis behavior whether you're cutting lap times or carving canyon roads on your B9 Audi.

Features & Benefits
✓
Teflon-Lined Spherical BearingsReplaces the OEM rubber bushing with a precision spherical bearing that articulates freely without deflection, giving your B9 Audi's front suspension a direct, unfiltered connection between strut and chassis.
✓
6061 Billet Aluminum ConstructionCNC-machined from aircraft-grade 6061 aluminum, the housing is dimensionally exact, corrosion resistant, and built to outlast multiple sets of OEM rubber mounts under both street and track abuse.
✓
Zero-Deflection Strut ManagementEliminates the bushing flex that allows strut geometry to shift under cornering load — keeping camber, caster, and alignment values where you set them, lap after lap.
✓
Sharper Steering ResponseBy removing the compliant rubber interface at the top of the strut, steering inputs translate more immediately to wheel movement, tightening turn-in and improving driver confidence at speed on the B9 chassis.
✓
Direct OEM Replacement FitmentEngineered specifically for the B9 platform — bolts directly into factory strut locations with no cutting, fabrication, or additional brackets required. All hardware included.
✓
Lifetime Structural WarrantyEvery TGK Motorsport spherical top hat is backed by a lifetime structural warranty — because hardware that sits between your suspension and chassis should never be a question mark.
Frequently Asked Questions
Will these spherical top hats increase cabin noise or harshness on my B9 Audi?
Yes — spherical bearing mounts transmit more NVH than OEM rubber bushings by design. That is the trade-off for eliminating deflection and gaining precise strut control. On a dedicated track car or an aggressively modified street build, most drivers find the improvement in steering feel and chassis response far outweighs any increase in road noise. If your B9 is a daily driver with a stock or lightly modified suspension, consider whether the NVH increase aligns with your use case before purchasing.
Do I need to re-align my Audi after installing these strut top hats?
Yes. Any time front suspension geometry components are removed and reinstalled — including strut top mounts — a full four-wheel alignment is required. This is especially important on the B9 platform where small geometry changes have a measurable effect on handling balance. We recommend a performance alignment after installation to ensure you are getting the full benefit of the reduced deflection these mounts provide.
Are these compatible with coilovers and lowering springs on the B9 platform?
Yes, and this is one of the most common applications. The B9 Audi's are frequently running coilover kits with spring rates that accelerate OEM rubber bushing wear and amplify their inherent compliance. TGK Motorsport spherical top hats are fully compatible with aftermarket coilover systems and provide a more appropriate interface for higher spring rates than factory rubber mounts allow.
How does the TGK spherical top hat compare to OEM-style replacement mounts?
OEM-style replacement top hats — whether sourced from the dealer or an aftermarket supplier — replicate the same rubber bushing design with the same compliance built in. They are a maintenance item. The TGK Motorsport spherical top hat is a performance upgrade: it eliminates the rubber interface entirely, replacing it with a Teflon-lined spherical bearing housed in 6061 billet aluminum. The result is a fundamentally different level of strut control and a part that does not wear out the way rubber does.
What hardware is included, and is professional installation recommended?
All necessary mounting hardware is included with each set of TGK Motorsport spherical front strut top hats. Installation follows the standard strut removal procedure for the B9 platform and requires a spring compressor to safely disassemble and reassemble the strut. Professional installation by a qualified suspension technician is strongly recommended, both for safety and to ensure proper torque specifications are met before a post-installation alignment is performed.
