Brands Hatch 06/06/24 Track Day, BMW M4 Yokohama AD09, Caterham/Westfield

Beautifully driven Westfield or Caterham type car. It was quicker everywhere but thanks to the traffic, yellow flag and the driver seeming to wait for me, I kept it in picture for a while. I really liked how polite he was, waving thanks when other people let him past and keeping distance from slower cars.
I'm a bit disappointed with the Yokohama AD09 tyres. The first heat cycle they did 52.9, second heat cycle 53.4 and today only managed 53.5. The 53.5's were in my last session:
Lap 19: 53.50
Lap 4: 53.51
Lap 7: 53.55
I'm going to do a review of these tyres but to anyone considering buying them, unless you can get them significantly cheaper than AR-1 or manufacturer approved Cup 2, I wouldn't bother. I paid £600 fitted for this set, which is about half retail price.

What pads are you running?
And what laptimes do you run?

PB is 52.4 but that was on brand new ar-1 and with car making a bit more power. On these tyres, 52.9 but they only did that once. Pads are EBC RPX.
