The RacingLine Alignment Bolt Collar kit is a simple ‘why not’ upgrade to eliminate the challenges caused by large tolerances in the factory subframe mounts, both front and rear.

The OEM subframe design uses really oversized bolt holes – giving a wide range of adjustments to shuffle the whole subframe assembly back and forth, side to side.

Whilst that may be ideal for dealers & repairers to lazily mask other misalignment in the chassis, it means that there are also huge opportunities for inaccuracy every time your subframes are refitted, not to mention the risk of the car’s alignment creeping out of tolerance with hard driving over time.

Our precision-engineered, push-in Bolt Collars centralise the subframes by cutting out the huge hole tolerances, so perfectly centring the bolt locations every time you refit. The result? With correct alignment, you’ll keep precise steering, sharper handling and braking responses every time. By ensuring complete accuracy every time you refit your subframes, you’ll save time and cost by ensuring consistent, hassle-free alignment each time, every time.  With no need for alignments after refitting subframes in future, this really affordable upgrade will likely pay for itself many times over.No additional NVH transfer into the car and no more creaking mounts.

Full kit of 16x Bolt Collars for front and rear subframes

High quality T6061 billet aluminium construction

CNC construction, anodised gloss black to last

Precision machining means tighter alignment specs

Simple, quick push-in fitment into OEM subframes

No modification to subframe or car body is required, so fitment is completely reversible.

Installation is straightforward and can be performed in approximately one hour.

We recommend replacing the original subframe bolts with new ones – as stretch bolts they are intended for one-time use only.

It’s critical to perform a full wheel/geometry alignment by a professional after fitment.
