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


Ever wished you could easily remove your rear diffuser easily, without assistance, without tools and in a matter of seconds? I know I have! I've put together this kit to allow all of the above.

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

It comes with 10 quick release fasteners and 40 parts all together.

Also available with Black fasteners, message us or leave a note on the order screen.

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 "bail" style heads provide easy operation of the fasteners. You do not need to fiddle around with tools and they do not hang down when upside-down. However if you wish, you can remove the loop and operate fastener using a flat screwdriver.


The clips are made from A2 stainless steel, the fasteners are made from zinc plate with chromate plus sealer to ensure they do not rust.

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

This 40 piece kit contains:

10 Quarter turn slide clips
10 Quarter turn fasteners
10 stainless steel washers
10 large retaining washers

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

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

Please visit our Lotus Elise S1 Section and Lotus Elise S2 Section for more Stainless Steel Fixings kits, including Clam Shell Kits, Under Tray bolt kits, Wheel Arch Liner fixings kits, Complete Overhaul kits and even Quick Release kits so you can remove the Undertrays in seconds!

100% money back guarantee if you are not happy with the kit.
