Description: Ginetta G40 Body Panels & Adjustment

Ginetta G40 panels are all made of gel-coated fiberglass, with the exception of the Junior cars from 2018 which have carbon-fibre door skins. The main body shell is bolted and glued onto the frame and can't be adjusted. Adjustments are only possible on the panels that fit onto the main shell: doors, boot lid and clamshell (bonnet). Those adjustments may involve sanding of the panel edges. Minor adjustments can be done DIY-style, as described below.

Boot and adjustment points

The photo below shows the three bolts used for adjusting the boot lid's fit into the body. You may find that the latch / locking mechanism doesn't work if you adjust too much. Use a 3 mm Hex / Allen key for these bolts.

The 200-litre boot and passenger space are good enough for a tool box, trolley jack, fluids and a few 5-litre fuel cans, so it's feasible to use the G40 as a club car, driving to the track if you keep it road-legal.

Door adjustment

The side doors are a weakness on the G40. You may find that they don't close easily and droop due to splits in the hinge mountings. Be very careful with the doors and don't lean on them, as the lower hinge mounting will probably crack in the door. You can only fix a cracked hinge mounting by removing the door and finding a way to re-strengthen it.

If the door is not closing, the best way to adjust it is to move the latch-receiving pin on the body.

If the door is not closing fully, loosen the latch pin and move it outwards, away from the driver's position. To loosen the latch pin, remove the rear road wheel and reach up inside the wheel arch to loosen the two 13mm nuts.

Door removal

Remove the door by unbolting the two pins / bolts that sit vertically  through the hinges.


The bonnet / clamshell is held down by two Aerocatches. The pins can break, such as from an off-track excursion. You can get replacements from Ginetta, or elsewhere, and they come in pairs.
