thats an MZ21 with all options, MZ20's don't always have all the options.
There are side skirts, rear pods, front bar and also a subtle rear tail lip.
OS Giken twin plate will handle the power but you will have to sell your babies to buy one, $2500ish + $600 for the install tool. It won't slip though!
Otherwise you will need an uber heavy button clutch of some description as it will make some torque!
