After nearly having my head ripped from my shoulders last time out at PI, it was decided that it would be best to add some sort of helmet aero to keep everything where it should be. Entering turn one deep in 6th gear without full concentration is not ideal, so anything that even remotely helps is a welcome addition.
A 3 piece kit was ordered consisting of the following:
Also added some tearoffs, which make life easy.
The difference was more than I was expecting,and it was definitely a worthwhile investment. We had less of a headwind on the day, but speaking to some other drivers it would appear they were getting quite a bit of buffeting while we were free to concentrate on driving.
All in all highly recommended!
