Does chopping the rear bumper "alter the silhouette"?

[Dave_P]

MSA road going hillclimb regs...

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).



Personally i think not as the fuel tank is the lowest part under the car so whether the bumper is chopped or not the silhouette remains the same.

Opnions?

My regs are more specific in that they state 'side' silhouette must remain un-altered.

Rear silhouette is un-altered I think, from the pic above.
Depends on eligibility scrutineers opinion though, and whether they like you or not!

[blackie_2k5]

silhouette refers to exterior outline... overall shape so im gonna say no

and the saxo bumper should hang lower then the tank unless the car is on stilts

[axsaxoman]

agreed under car has neverbeen considered part of silhouette in my experience

I'm sure i've seen a diagram which did not include under the bumper.

It'll be interesting to see what the scrutineers say if i enter my vts at a hillclimb with the bumper done.

i took the spare wheel brackets of and it doesnt look as if there is something missing from the bumper! cut exactly on the line and plastic welded the inner brackets
