These are the pads we used on our Grand Am race winner E92 M3!

Although RS19 is quoted as being at the same average friction level as RS29, the initial bite is smoother, and if disc temperature is controlled will generally exhibit slightly lower pad and disc wear than RS29, a slight trade off for the increase in initial bite.
This compound provides very good levels of performance and response at all temperatures, only slight temperature inputs are required to bring the pad up to its optimum performance level. RS19 has gained an enviable reputation at the world’s most grueling endurance racing events, such as Le-Mans, Daytona 24 hours, Nurburgring 24 hours, Spa and Silverstone 24 hour races. RS19 is a multiple winner at all these events.
RS19 is also equally at home at the harshest of track day events, and is used by some of the world’s best operators of track day and corporate driving experiences. Giving the customers a safe operating environment, while offering the operators a cost effective solution to brake pad and disc consumption. While not being the cheapest brake pad on the market, we have proved time and time again that with the combination of longer pad life and lower disc wear that running costs over a season can be significantly reduced, when compared to cheaper, inferior products.
