To all orders other than UK, please note that Standard Shipping or Royal Mail Airmail can take up to 3 weeks to arrive, not the 3-5 days that ebay quote. If you need the parts sooner, please choose the International Tracked option or ask us for an invoice with an Express Shipping price.


eBay is changing the way they score sellers. Please say "yes" when asked if you received the item on time. If we receive too many "no" scores we will have to enrol into the Global Shipping Programme or get every item tracked which will put costs for buyers up greatly.


Please request an invoice if you're buying multiple items and/or the postage is too high, we will adjust it.

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 undertrays 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.


PLEASE CHECK IF 20 FASTENERS WILL BE ENOUGH, AS SOME OF THE 111R MODELS HAVE 11 HOLES AT THE REARMOST PART OF THE REAR DIFFUSER. THE EXIGE 24 PIECE KIT IS NEEDED WITH SOME OF THESE MODELS. CONTACT FOR ADVICE.


This is a quarter-turn quick release kit for a Lotus Elise S2 (S1 and Exige kit available in my shop). It replaces the existing m5 size bolts and clips on the rear diffuser (original m8 bolts are retained).


It comes with 20 quarter turn fasteners and 80 parts all together. This will secure the rear undertray and diffuser. 

Undertrays are not included, this is just a fixings pack.


This quick release kit saves a great deal of time when changing the rear undertrays, 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 80 piece kit contains:


20 Quarter turn stainless steel clips

20 Quarter turn fasteners

20 stainless washers

20 large retaining washers

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