No, I actually tow my drift car with my X. I really just want it RWD and 5 speed because it would be more fun, better gas mileage, and a lot less parts to fail.
The T56 while being a great transmission, shifts like crap and would take a lot of extra fab.
The 3.0L V8 trans is the same of the e36 M3 ZF box, but on a bell housing that bolts right to our cars. Super strong trans that holds up to the constant abuse of my race car that makes nearly 600tq at the wheels... Meaning itll hold up to my 270ftlbs my X5 made on the dyno last year.
Here is my drift car.
