Circuit of the Americas X1 s28i M Sport
I'm better at driving than uploading, but I have a video of my 2014 X1 s28i M Sport at COTA near Austin, Tx.
Car runs cooler when driving hard in which I usually hit approx 120 mph on the straights of several courses including High Plains Raceway near Denver.
I have Pirelli P7 summer performance 255/40r18 and 225/45r18. I put 12 mm spacer on front only to even the track closer, ans stop the sway. Stock, the rears are 2 inches wider with the staggered, so now the rears are only approx 1 inch wider.
I have scanguage to measure temps, and it runs about 209 deg when jumping on and off the gas as in track day. Cruising, the engine knows you aren't dumping excess heat so it can run water temp up to 236 f for efficiency.
