The car is a standard S240 with a de-cat pipe and an exhaust. Stock brakes, stock shocks, stock tires. The shocks were set at 7/8 as per the recommendation of several posts on this forum (and the Lotus manual), but I think next time (for my driving style) I will increase this by one front and back.
I have lots of track time at Sebring (and most other US tracks) in formula cars, so I know the racing line and am very familiar with Sebring. Several other posts are correct in their comments about the other cars--some of which may be faster than the Exige if more experienced drivers were in them--but, as can be seen in this video, I only hold back a few times (not a safe passing opportinity). However, the GT3 (which leaves us in the dust on the back stretch but is passed for good in the Esses) is not faster anywhere else on the track than the Lotus, and in many areas the Lotus is faster. The driver was an instructor for the PCA, and is very experienced. We diced several times during the day, each time we win 80% of the track (he wins the back stretch), and we win the lap.
Bottom line... these cars provide a great platform for the beginner "racer" as well as the experinced driver with lots of track time. When you drive these cars as they can be driven, you can kick almost everybody's butt. I treated this car very roughly (this was my first time in the car on the track--just got it 2 months ago), but it never let me down. Very dependable, perfectly predictable in what it is doing, and excellent at giving feedback to the driver.
