GPR Tab spacing
I was looking at my tabs tonight and found some oddities on the spacing from front to back and side to side.
Are there optimal measurements ? Does it matter which tabs i.e. stock/shortened/extended.

* when you say oddities, are these measurements you are finding by measuring with a digital caliper ?
* it depends on how much spacing there is by how you are tuning in your handling. Typically, washers are added to control porpoising and add lateral stability.
* the aftermarket R&D tabs have extensions on them to add more stability in rough water. These extensions entend the hull length which in turn will put more of the nose in the water (reduce lift)
* some people "cut" the extensions off and imitate the stock length of the OEM tabs.
* some people also run the OEM tabs and add washers to them.
* the aftermarket R&D tabs are thicker than the OEM tabs by roughly .110 if memory serves right.
* some people will also take the tabs off all together.
* It all depends on what you are attempting to gain
i.e.) more stability, more top end, more rough water control ect.....
* also look too, the OEM tabs are not "flat". They are tapered thinner toward the inside of the hull. the outer edge of the tabs are thicker than the inside edge.

I am also getting different measurements from side to side on the ride plate.
I keep thinking it should all be straight under there mine is definetly not centered. I have shortened R&D tabs on there now that are polished. It may be in the tolerances of the Tabs.
I know I have read somewhere about opening up the tab mounting holes a little.
