street prepared legal engine lowering
Has anyone considered lowering the engine in an early model z/g with later model motor and tranny mounts. I read somewhere that the engine was lowered in the later model G--not sure by how much. I've included part diagrams for the early and late model Z mounts. They appear the same as the G minus some additional dampeners. I'm guessing that they can be found in a salvage for a reasonable price.

All I know is on my 03 if I lower the motor an inch that puts my oil pan almost level with my crossmember... My crossmember has smacked the ground a few times, I don't want my oil pan to smack the ground!

I remember reading something about some solid or megan end mounts lowering the motor.
Lower center of gravity.

Stock oil pan actually sits pretty high, even with an oil pan spacer it sits above the cross member. My Greddy oil pan still sits well above the crossmember and barely clears the GT spec V1 brace.

Changing the position of the engine is not allowed in SP. You must use an engine mount style that came with the engine (not the chassis) and it cannot have more metal that what was OEM. Remember, in the SCCA Solo world, if it doesn't say you can, you can't and the argument that the engine position change as a result of legal modification is legal has been tried many times and failed just as often.
Now, if the engine mounts are worn or the mounting holes have been worn into an oval shape, then the resulting engine position change might be legal. But make sure everything is "worn."
