Silhouette Clarification?

[Ian Johnson]

If i try and explain what i want to do.....can you tell me if this will affect the below:

Body (including aerodynamics)
11.4.1. Silhouette of the vehicle must remain unaltered
in construction, dimension and material. The silhouette
will be taken in the condition in which the car competes (convertible closed cars competing with the hood or
top not erected shall have the silhouette determined in
that condition).

I want to remove the rear Hatch from my car and enclose the sides and back in perspex (ala ferrari dino) when competeing in speed events, but will still allow me to fix the rear hatch in original position for homologated circuit racing where the original glass must be used.

Is the Silhoette just a side view?

A 246 Dino has a vertical rear window, surely your current set up will be far more 'slippy' and aerodynamically correct. However, I think it will be ok silhouette wise..........

11.4 relates to roadgoing cars. Surely yours is in ModProd?

If its modProd you'll be fine.

12.5.1. The silhouette as seen in side elevation must
remain unaltered above the wheel hub centres of the
original car, except for engine bonnet/cover and boot
lid/rear deck.

you are probably right with regards aero but on the hills and sprints would i really notice in the old bus ..........the weight of the hatch must be 30kgs and need the stock glass left in for Circuit racing.

This is the look i was thinking of........Lancia Beta Montecarlo ...........yes, yes i said Ferrari Dino but similar designs

Thats entirely differant, but looks nicer...........

Who is this 'Silhoette Clarification' anyway?

[volvorsport]

darrians are like the monte carlo , aerodynmic testing has proved a faired in one is better , ie like std .

of course if you were altering it so you could sneak in wing in there , it might be a different story .

whats wrong with a GRP tailgate ?
