I have some experience with them. Used to work at a shop where I aligned and did suspension work on them. IMO, you'd be better off building a chassis from scratch around your driveline package than starting with any of the chassis that make the basis for any of the Lotus 7 replicas. By the time you cut up the chassis you'd probably only would be left with the front clip and none of those chassis have much to write home about as far a front end geometry. The Locost chassis uses a Mazda Miata donor for the driveline and basic suspension pieces. Then you have the Brunton Stalker, it uses a Chevy S-10 as the donor, and the Ultralite XR7 uses a mish-mash of Honda and Subaru components. None of these cars are very good as built by the directions. They're like most kit cars, they work well enough as stylish cruisers but take a total rework to make them actually work.
