RCF bonnet lifts at speed

[jonpaul]

Hi, my bonnet lifts about 3 to 6 mm on drivers side when driving over 70 ( on private roads ! ) all rubber bonnet seals seem ok and nothing loose. Has anyone else had this ?

No it shouldn’t lift.

Is this towards the back (nearest the windscreen)? if so there are usually a couple of hooks at the back of bonnets make sure those are there and working properly

Anything to do with the pedestrian active bonnet? Maybe it's been activated and not correctly reset?

Nope because the RC F doesn't have a popup bonnet.

Interesting you're noticing this. 

 

Ever since I bought my ISF brand new I've always noticed my bonnet lifiting at high speeds. 

 

I have driven my car on high speeds the first 4 years of its life at high speeds nearly daily and everything seems ok, apart from seeing the bonnet from the side when at high speeds it does look slightly lifted. 

 

You can see in the below Video at the end where my bonnet looks lifted:

My RCF bonnet lifts slightly near windscreen by 5mm or so and has done from day one, nothings loose or broken

happens with the OEM steel bonnet and my 2 carbon bonnets…. Wont lift at all when parked up and i pull on it at windscreen  edge,

so as far as I’m concerned its meant to do this…one of a kind aerodynamic model 😂 

sure i read somewhere this is meant to happen but obviously imagined it as search everywhere and no mention of it
