Well I think the diffuser must be working, whent to Donington today (bl00dy cold) and im not sure what has happend but on the way home looks like somthing has hit my RS2000 ally sump and put a dent / split in the sump.....

needless to say its been leeking like a sive on the way home but luckely not enough to run dry and lose oil pressure.
Only noticed it when i made a detour on the way home to see my perents and my mum aske what was leaking, as there was an ever increasing pool of oil under the car.
Nedless to say theres loads of oil spray under the car yet not a drop on the rear bodywork so i guess the diffuser is doing somthing..........
