034Motorsport is pleased to present the Stainless Steel Subframe Locking Collar Upgrade Kit for the MkV/MkVI Volkswagen Golf/Jetta/GTI/GLI/R32/Passat/Rabbit & 8P Audi A3! Designed to center the subframe using precision-engineered stainless steel insert bushings and large-diameter bolts, this kit eliminates clunks caused by the subframe shifting, and increases chassis rigidity for improved handling performance.

This kit addresses the very common subframe clunk/pop/creak that presents itself when taking slow turns, entering driveways, coming to a stop, and starting from a standstill. Unlike the band-aid shims used in the factory Volkswagen Technical Service Bulletin (TSB V-401202 & Others) repair, these locking collars and upgraded bolts are a permanent, affordable solution to address the fundamental issue with the factory subframe design.

The upper and lower collars in our kit are specifically machineded to locate the subframe and bolts perfectly and ensure hassle-free installation. The supplied bolts feature factory-correct tips and thread engagement points to prevent thread stripping. Unlike other kits on the market that use softer alloys, our Mk5/Mk6 VW Golf/Jetta/GTI/GLI/R32/Passat/Rabbit, Audi A3, Subframe Locking Collars are made from stainless steel to prevent deformation and ensure a lifetime of performance.

Installation is very straightforward and can be performed in approximately one hour. No permanent modification to the subframe is required, and this upgrade completely reversible.

Features:
  • CNC-Machined Stainless Steel Locking Collars
  • Application-Specific Design for Both Upper & Lower Locking Collars
  • Engineered to Properly Locate (Center) Factory Front Subframe & Eliminate Shifting/Clunks
  • Includes New Large-Diameter Subframe Bolts to Prevent Loosening

Excellent sound deadening mats
Style: 80 mil 36 sqft, Style: 80 mil 36 sqft
Purchased these for a 2020 Lexus RX350 due to the hollow sound of the car doors when shutting. They sounded cheap. The mats are super sticky and I applied them when the doors were hot from sitting in the sun. They alubutyl sticks like crazy and the end result was perfect. Now I have solid sounding doors. Good quality product.
