It might get down to the crazy nitty gritty measurements, or go way past what anyone really should know, but this is what we worked out.
From measuring the axle mid point to the end of the baseplate, Thunder is only 2 mm less than the next top brand, which is Venture, then a bit more again (3.5mm if I can recall) for others like Indy and then a bit more again for Ace (4.5mm or so) but it was quite a while ago, so I could be wrong with the figures, but I think it did go in that order.
It was interesting to measure those, as we had to check and take into consideration other things like the mounting holes, but it turns out the things like wheelbase, length of kicks or mounting holes are not relevant to the particular topic of "Whether or not the baseplate sticks out enough" as it is the axle to the end of the baseplate, as mentioned above.
The other really interesting thing in determining nose / tail slide contact with the baseplates is the concave and kick angle of the board, so if a board has more concave, with steeper kicks, there is much more chance of the Thunder baseplate touching on nose / tail slides. Also if people do slides while sitting lower, rather than higher on the nose / tail, there is much less likely to be any baseplate touch on the edge as well.
I am sure people have looked at a board on a ledge, with the kick flat on top (nose or tail), in the same way that you would put your board up to drop in on a ramp, which is way more relevant than some other examples of the different truck brands not actually in skateboarding positions.
When I have a minute, I can take some pics too, but if anyone is actually doing measurements or tests, it really needs to be on the same wheels and the same deck, to minimise variables.
Even between two of what should be the same setups (with different trucks, but same deck, wheels, etc) things still worked a little differently, but I think that is pushing it almost too far, isn't it?
