how much do people lift the bonnets by

 

I made my own and they are 30mm thick, Not got round to fitting them yet though As i hate ligning bonnets up at the best of times

 

thanks it is about time i have ask in three places on this site wot did you make them out of mate just steel or rubber

 

Mine are 20mm, and are precision machine cut out of 10mm clear perspex, can be painted if needed but mine aren't.

Gonna make some various 5 and 10mm ones, gives a choice from 5 - 25mm.

 

This is an old system not a new idea-------- used on my road rally car for years to get good air flow and in winter to keep screen clear , (((derbyshire can be icy on the moors)) but on a removable /lift of bonnet---- on a hinged one to much lift and you wont open the bonnet!!!! lol
