After trying all of the seats I could find that fit into Elise/Exige cars, I was left with nothing that fit the bill. I'm 6'2" and ~220 pounds and they were either too narrow, too short, too flexible, etc.
I finally found a company in the UK that makes a Lotus-specific seat as well as seats for other small cars.

I've been working with Tillett seats in the UK to import their car seat lineup. It's been a difficult road because the brackets they offer are not for US-spec cars. I commissioned a local race shop to fabricate brackets and jigs to produce brackets that will mount to the driver's-side sliders as well as provide a secure fixture for an anti-submarine belt. The passenger side is a one-piece bracket for both left and right that incorporates the same cross-bar for a fifth harness point.
In addition to multi-point harnesses, the seats and brackets will work with the factory three-point system.
At this time, the seats and brackets are not available. It will take a bit of time to ramp up production for everything. During that time, I'll be building a commerce site as well as a physical, brick and mortar site here in Virginia in which to house inventory and ship from.
Pricing is not defined, though they will be much cheaper than similar units from other manufacturers.
PS: Randy, if you happen to read this thread, please reply to one of my queries about becoming a vendor and site supporter.
