Williams S2 pads

[Doug P]

I asked Williams for pad advise for the WOSCA lapping day. I have been using the S2 pad for a year, up to now Solo 2 and street only.

They advised that my S2 pads would likely begin to fade after 5-6 laps, requiring a cool of of 30 minutes. The other consideration was that they advised these pads would likely be used up in a day requiring new pads.

I thought about swapping to the F1.05 pad to allow limited street use (changing at home) but decided to start the WOSCA lapping day at TMP with the S2 pads swapping to my old stock pads to get home.

I was very happy with what I found at the track. The pads worked well althought they did start fading after 5 laps as advised. Not bad for a 3,600 lb car. I found that I could stay on the track and back off slightly (98%, a couple of seconds on a 85-90 second course) to contine lapping with no issues.

I kept an eye on the pads expecting them to be gone in the day. I estimate I still have 1/2 my pads left, great! Lots of brake dust, everything is black.

If I were to put the effort into changing pads at the track I would swap to a full race pad to be able to stay out longer at 100% otherwise the S2 pad was great.
