Lotus Elise Series 1 and Vauxhall VX220 Quick Release Kit for Rear Under Tray Diffuser


Since repairing my own Elise's, I've been developing these kits since 2006, with many happy customers! 


This is a quarter-turn quick release kit designed for a Lotus Elise S1 but will fit an Exige S1 or Vauxhall VX220. It replaces the existing m5 size bolts and clips on the rear diffuser (original m8 bolts are retained).

It comes with 16 quick release fasteners and 64 parts all together.

This quick release kit saves a great deal of time when removing the rear diffuser, making them oil changes and pre-track day inspections a lot easier. Also comes with nylon retaining washers to keep the studs in place when unfastening.

These posi/crosshead style heads provide easy operation of the fasteners (just use a posi screwdriver). 


We have sourced improved retaining washers to prevent studs from dropping from undertray when being removed.

This 64 piece kit contains:
16 Quarter turn slide clips
16 Quarter turn fasteners
16 stainless steel washers
16 large retaining washers

100% genuine Dzus, made to the high standards required by aviation, GP & F1

Fitting guides can be emailed to you upon request, just contact us.
