Paul, With either seat the top point of the pyramid of traction control is the seat/driver. The bottom is the tires contact points. The taller the pyramid is will increase the amount of  vertical force upon the contact points when trying to change direction.

A lay down seat set up would need  narrower and shorter contact points in order to try and equal the vertical force that a sit up seat would have.  At some point in width and length decreases it would not be able to produce as much vertical force upon the tires.

Horizontal forces and dirt reduce grip .

I have tried to yet my lack of regular maintenance has eliminated the need for a compression tester to tell me when I have lost all my compression.

Ray, I have been doing some compression testing .  My rotax was at 150 pounds cold in Grand junction. It tests less with less air density like at my shop. I tested Norberts Pavesi after a fresh piston and ring at SBR and got a weird low reading , even tried a different gauge and still got a low reading while it ran great on track.

I am finishing up my shifter motor rebuild and will be doing a low pressure 10 pound leak down test on the bottom end just to see how the case gasket and seals perform.

Take a look at how your throttle cable is or is not protected from the leg of your racing suit laying against it causing it to stick open.

I can ‘t keep my head up for a twenty lap main any more. I have one of these cheap neck supports from years ago and just tried it with my helmet on.  http://sell.lulusoso.com/selling-leads/1385742/Philadelphia-neck-support-common-.html

It seems to support my head from tilting back.  The Simpson pro-rag looks like it would do nothing for forward support of an old mans neck. Has anyone ever tried a D ring in the chin of a helmet strapped to a waist belt?

IMO it needed a new piston and ring about a year and a half ago.
