Racingline Subframe Alignment Kit / MQB / MQB EVO

RacingLine Subframe Alignment Kit – MQB / MQB Evo

The RacingLine Subframe Alignment Bolt Collar Kit is a precision centering bushing kit for the subframe, developed for VW, Audi, Cupra / SEAT, and Skoda MQB / MQB Evo vehicles.

The factory subframe design uses significantly larger holes around the bolts. This allows the entire subframe to move forward, backward, and sideways during disassembly, assembly, or under heavy load. In service conditions, this tolerance might be convenient, but for an enthusiast who values precise geometry, accurate steering, and stable handling, this is a weakness.

RacingLine solves this problem with precisely manufactured centering bushings that are inserted into the subframe holes, eliminating the excessive factory tolerance. This ensures the bolts are precisely centered every time the subframe is removed and reinstalled.

The result is more accurate positioning of the front and rear subframe, more consistent geometry, a more precise steering feel, and more predictable behavior during braking and cornering.

This is an especially useful upgrade for vehicles driven dynamically, using stiffer suspension, stickier tires, or frequently serviced for suspension. The kit helps geometry stay where it should, instead of shifting due to factory clearances.

The bushings are made from high-quality T6061 billet aluminum, precisely CNC machined and finished with a gloss black anodized coating for long-lasting protection. Installation is direct, by inserting them into the original subframe holes, without the need for cutting, drilling, or irreversible modifications to the vehicle.

• No additional noise, vibration, or harshness transmitted to the cabin
• Helps eliminate squeaky subframe mounts
• Complete set of 16 centering bushings
• For front and rear subframes
• Made from T6061 billet aluminum
• Precise CNC machining
• Gloss black anodized finish
• Easy installation into original subframe holes
• No cutting, drilling, or body modifications
• Fully reversible installation

Why this upgrade matters?

On MQB and MQB Evo platforms, the subframe has factory holes with large tolerances. This means that during disassembly and reassembly, its position can change, even when everything appears properly tightened.

This small difference can affect geometry, steering wheel alignment, braking behavior, and cornering accuracy. The RacingLine Subframe Alignment Kit eliminates this excessive play and helps the subframe return to the same centered position every time.

Installation

• Installation is direct and involves inserting the bushings into the original subframe holes.
• RacingLine indicates an approximate installation time of about 1 hour.
• It is recommended that the original subframe bolts be replaced with new ones, as they are single-use stretch bolts.
• After installation, it is critically important to have a full geometry inspection and adjustment performed by a professional service.

Important
