The filler cap broke
The car felt really good round the Ring, puts the power down really well - loads of torque & predictable. It was wet in places, had to take care.
But suspension is in need of some work, several knocks appeared today. Think the strut bearings have gone, & at least one of the driveshafts mmm..
I was going to change the set-up so perhaps a good opportunity to get it sorted. Amazing just how demanding that track is on a car.
Based on today I'd imagine your car would be insanely fast round the Ring.
