Jon and Wayno (forever),

Yep, Yep and Yep.

As a point of interest, how come moon disks aren't scuppered under aerodynamic body work?  Is it because moon disks are part of the wheel and hence not bodywork?

How do we define the "narrowest wheel dimension" exactly? I don't want to trip up here.

Is the spirit of the law nothing covering the external rotating wheel? What is the established build practice?

Dik, for example if the front wheel inside dimension is narrower than the rear, the streamlining on the rear axle must be narrower than that front dimension. Regarding the Moon disks, I would think if they're attached to the wheel and spinning with it they are considered part of the wheel and not streamlining.  :cheers: Wayno

What streamlining do you have on the inside of the wheel?

Just run a flat plate attached to the axle (axel for our US readers)

We don't have to move the tie rods up as Goggs will be moving the front axle down to deal with the new front tyres

Huh?....people read this in America?.... :roll:

Don't they have TV?

Answer is yes, and likely changing the ball joints to heims...and changing those little king-pin bearings too.......

Axel Franzen was the old Norwegian gas station owner next to the restaurant my aunt and uncle used to run.  Axel worked on axles.

Streamline issues
« Reply #4060 on: October 22, 2013, 12:16:53 PM »
Hmmm... I believe we designed the front wheels to sit in line with the rear wheels so they were in the hole (read chaotic turbulent mess) that the first wheels made.

We did consider issues of salt being kicked up and hitting the rear wheels, stability issues such as wider track at front is more stable, and the like but ended up with a pretty straight front to back configuration.

Thanks Wayno for describing the rule as I was not aware of this little nugget and it would have been the convincer to make it happen the way we did... I think. Dr G can you check that the inner dimension of the front wheels are the same as the back? It may be slightly out due to wheel thickness and offset of rim.... Whatever it is it must be damn close and we don't want to break any rules now with these aero parts.

First rule of architecture is to always site measure and don't rely on drawings so get that tape measure and brave the heat.

Those limeys wish to remain anonymous however one took a job in another part of the UK so it may have broken up the band. I'll send them an email and see.
