4.1 ...........The chassis may only be shortened forward of the front tyres and rearward of the rear tyres..........

4.4 The wheel base may be altered by moving the axles either fwd or rearward from their OEM position
provided they stay within the original chassis frame work.

The way I read the above is you can move the axle so the wheels stick past the chassis as long as the axle is within the chassis dimension, but you can not shortern the chassis to achieve the same wheels protruding effect.

I am suggesting that 4.1 be altered to read "the chassis may only be shortened forward of the front axle and rearward of the rear axle"

Thoughts??

I'm glad you brought this one up Dan as I read it the same way. Obviously one or both of these rules needs re-wording to make things clearer, but the question is whether we restrict things to a max 90 degree approach/departure angle, or allow the tyres to protrude past the chassis rails?

Yeah and I'm building my new truck with the front tyres stick out past the chassis BUT it will have less than 90* approach angle due to bar work etc.
Personally I don't have a problem with bobtailing etc and if you can shift the axles then who cares where you shift it too or cut the chassis.

One thing to think about is the Oz rule where the factory chassis is required between the axles (or something like that). That way past the axle you can cut off the chassis to make mods easier / cheaper.

I know this is moving more away from factory chassis but what is really important. Restricting mods or making the sport cheaper? With how many of us do all our own work, modifying chassis etc is cheap but finding a way to get around a chassis mod can be quite dear.
