I have not been tracking much lately:frown:But have been using the ferodo 2500 pads.For those of you doing some track events but more street miles these are excelent pads.I have found them to have good cold bite ,adequate endurance hot, very little squeal.:smile:I have used both oem and cobalt gt pads in the rear.Now the downside(there is alway a downer) they are dusty and if you are not judicious in your wheel cleaning will leave dremel requiring stains:frown:As a last positive they are quite long lasting.If you decide to use them I ordered the thinnest pad available which fits my old brembo/comptech 12.4 kit best.
