i'm thinking of changing my full windscreen to an aeroscreen to make life easier during the sva test.will ordinary black tinted perspex do or does it have to be of some safety spec?

Simply remove your screen for the SVA!

Mine was solid black, but just went through as it was just under the max height.

Hi Pat,

just out of interest what is the max height and do you get any deflection from it?

My aero screen is about 5inches and doesn't do much - I was just wondering if I shpuld put on a higher one for a bit less buffeting

Cheers Chris

Chris, Max height will depend upon the hight of the driver/tester and the height of the seat as i believe its all governed by line of sight based on the view the driver has of the road etc.
