This depends on which C111 chassis model you have and if you want to install a harness belt. The standard Elise S1, 340R, Elise S2 (pre VIN:72400), Elise 111R (pre VIN:32403), standard Exige S1, Exige S2 (pre VIN;82395) can all be bolted directly to existing Lotus seat frames.
On other later models, we sell seat frame adapter kits (for the Mulsanne C,XC and XRC and a separate one for the Mulsanne B) that allow you to mount our seats to the existing factory Lotus drivers side seat frames, maintaining the slide adjustment fore and aft. If you need to fit harness belts then we also offer seat frame adapter kits featuring a double shear inner bracket and longer 7/16" bolt.
If you are not concerned about keeping the OEM seat sliders and want to save even more weight then we have a solution in our specially designed steel side mounts. They have an array of holes and slots allowing for plenty of adjustment.
Our subframe adapter kits also cleverly allow you to retain the stock 3-point lap belt and or fit an additional 3,4 or 5/6 point harness system.
See below for Mulsanne C, XC, XRC (Narrow) Specific Lotus Sub-Frame Kits;
Lotus Elise S1, 340R and early K-Series engined Elise S2 all had the same rear seat bracket hole spacings/drillings and our seats fit these. The 340R featured double shear rear seat mounting brackets both sides to allow the fitment of harness belts. For later 111R Toyota powered cars (i.e Elise S2 and all Exige S2/2-Eleven), Lotus changed the rear bracket hole drilling positions and hence our conversion kits are needed to allow our seats to bolt in. You can also use our conversion kits to convert any Lotus sub frame to double shear to fit harness belts with our seats.
