I've been driving with Sport mode while I learn the car, so the assists are all engaged. If it's working hard it's been in the background - only a few times did I ask too much of the car jumping on the throttle out of a corner, and in those instances I felt it cutting/holding back power. I think there is a very real possibility that it IS working hard in the background and I could be engaging the brakes far more than I know. Next time out I owe it to myself to run without assists and see how much bad driving it's masking on my end. In all my forum readings I recall a post where someone remarked on the brake system pressure spikes they were seeing with some type of monitor during a track day, and that they were amazed at how active the brakes were beyond what we think of as normal braking. I'll see if I can find that again.Thanks for the write up on the wheels and brakes. Might your fluid boiling issue and maybe pad wear on the track be linked to the traction control applying the brakes to control wheels spin? or do you select it off on the track?
After speaking with the Endless US rep, I decided to move forward with the Ferodo DS1.11 pads. The Endless ME20 compound is not a typical offering in our RS size, so my options were either to buy it from someone abroad who has it in stock (will they have it in stock next time?), or to wait 3 weeks for a custom batch to be made, and then pay for them quite handsomely. Essex Parts Services carries the DS1.11s in stock in North Carolina. Both pads have very good testimonials over on Rennlist, the Porsche forum. There is a wealth of knowledge from the GT3 guys who run their cars frequently and to high speeds, plus they're all old dentists so they like writing up all their findings to share. Both the ME20 and DS1.11 had solid positive reviews over there.
