Bert - I've got a couple available. One (High Downforce) just been repaired to replace missing piece from the leading edge - only needs a lick of paint another earlier one that will be repaired next week.
If you are using a rear wing Martyn at MVS Racing has developed a front spliter/difuser like the radical uprated one for about 1/3 of the price... I used it last year with excellant results, would sort out some of the front end understeer??
