These carbon fiber louvers are for the front fenders on Lola T87-90 to T91-90 S2 cars that have the original non-louvered nose. Being 100% carbon fiber they are very stiff and it is unlikely they will fit nicely on other cars. The footprint for each is 13.5" x 7".
$200 plus shipping from SW Connecticut.
