Well now that the dust has settled and i've had a bit of time to go over the car i've found a few things as a result of the day:
Both front brake discs have hairline fractures everywhere on the donut's so that explains the vibration felt while braking after the first sessions. Replacements needed
Underbody is fine despite the grass cutting sessions, although the underside of the front cf lip copped it a little bit, there's no real damage
Front brake pads need to be replaced (time for ferodo ds2500's)
A second set of rims will be needed for track days!!!
