Before clicking the order button... Did you consider choosing the new brake pad standard for the Elise platform?
CL Brakes are this new standard and have proven to perform better than RS14 pads.

These pads have always been rated as very good for serious track use of Elise equipped with steel brake discs.
The RS14 is a racing brake pad with a high ceramic level. Very stable in terms of fading and will resist constant brake temperatures up to 650 ºC. A new mechanical way to attach the actual pad to the metal backplate will prevent the pad from coming loose.

While cold, the RS14 is as good as the RS42, at or above 400 ºC, you will definately experience more grip from the brakes.

The RS14 is developed for lightweight cars and is suited very well for the Lotus Elise/Exige.
