On Monday I went to a track day with a couple of mates in M3s, one with a LS3!
I knew the Michelin TB15’s wouldn’t last long with the heat so it was time to see them off, they have done 3000 miles including a track day at the Nurburgring. I’ll probably buy some narrower wheels for track days so I can run some cheaper track tyres.
The gearbox started to get a little tight after a few laps so I’ll look into fitting/developing a 915 cooler kit. Oh, I also need a diff badly!
