Thanks..I can make myself a template now!

This is the current state. I’m using 20mm steel tube for the body shape to be covered with 5mm ply, one or two layers of glass and a finish of body filler…..lots of sanding! Dave.

Thanks for all your input. Now 10 months later, I have progressed to making the body, after getting the Suzuki running for the first time ( albeit for 25 seconds). Now satisfied that it runs, I’ve begun building a steel frame for the body. my thoughts turn occasionally to the deflector. ( not windscreen!). I know that the IVA diagram shows dimensions that must be achieved ie max height, but there is ambiguity I think. Does the length A include the 93mm at the seat base or does one add the two together?

How do I take the s/wheel off my mx5 donor car? Battery is out and some of the loom.

Hi guys....apologies for late response. After spending £25 on a fiesta MC/servo I now discover that the MC I had has actually two outlets! one was being used by the pressure switch which fooled me. I can simply put the switch on a tee piece on one of the circuits. you are not allowed to use adjustable pressure valves in line, IVA rules!. There is a trike version but the weight limit is 450kg.

Single driven wheel at the back. Sierra discs at the front, bike disc at the rear. I’ve taken off the m/c and servo which was driving a single circuit and am now considering a dual 19mm m/c, with some sort of restricting valve on the rear circuit to prevent lockup.

Hi all. I’ve just acquired a part built 3 wheeler running a 900 Suzuki motor. Needs the dreaded Iva test, but need lots of input. For starters, I believe I need a split circuit for the brakes. How does one proportion the braking circuits? One circuit for the fronts, and one circuit for the single wheel?
