I'm not real happy with the aluminum plates in use. The danger is bending, and if 5/16" steel is enough, an aluminum plate has to be 15/16" for the same rigidity.



Thats the reason for the engine limiters... even a
1/4" alum plate will handle the vertical load but as
you said the fore/aft the plate would bend thus the
limiters come into play... some just use the trans
mount to control the fore/aft movement but on a hard
launching car it'll tear that mount apart... I prefer
the limiters... I use 2(one on each side of the engine)
others use just one... another reason I prefer the
limiters is, with just the rubber trans mount and
the engine moves back it can/will bottom out the
drive shaft into the trans creating a bind and the
possibility of breaking the tail shaft on the trans
