I think the SH has active steering, enabling faster track times. I am not an expert, but I think the SH is the preferred model.

 

The SH model has something called ATTS, which improves handling. If less traction is detected while turning power is sent to the outside wheels. The only bad side to the SH is that is a bit more heavy. How much more? I don't know.

I think SH stands for Special Handling.

 

The Type-SH has ATTS, different wheels, spoiler, body colored side and rear skirts, courtesy light on the doors, and, yes, it is about 300 lbs heavier.
