This seems to be a problem with all drivers seats. How do you know if it's the issue above? My seat rocks about .3-.5" (as measured at the headrest)Component: driver's-side seat rails
Location: under the driver's-side seat
Problem: seat rails have been installed improperly
Symptoms: driver's seat has slight forward / rearward "play", clunk under braking or acceleration
((Photos to follow))
If your driver's-side seat has been removed and reinstalled improperly, it can cause a slight forward / rearward "play" under braking or acceleration.
There are four bolts that hold the seat rails to the chassis of the car: two at the front of the rails, and two at the rear.
Since there are extra threaded holes near the proper seat rail mounting points, it is possible to chose one or more improper mounting points when re-installing the seat.
If 3 of 4 bolts are in the correct holes, the two seat rails will no longer be parallel and this can cause the problem outlined above.
(Sorry reviving an ancient thread, but hey I used the search feature!)Component: hard top panel
Location: like, duh.
Problem: bumper pad worn or missing
Symptoms: loud rap or bang when car hits bumps
There are many places that the hard top can make noise. One that isn't immediately obvious is the rubber bumper pad located at the rear latch block. (See photo). If yours are worn or missing, the hard top will tap against the latch block and cause wear and noise. Lotus has a replacement kit.
