sm or sp?
 

i'm not quite clear on what class my car would be in its an fd.. mods are..

gutted car
streetport
99 spec turbos
fuel pump
radiator
full bolt ons
buddy club d1 spec coilovers
megan tie rod ends, trailing arms and toe control links
underdrive pulley

and i think thats about it

Definetely not SP legal, and possibly not even SM legal due to the gutting.

streetport => SM
turbos => SM
radiator => SM
interior => Prepared

Xp

Put the carpet and the interior back in the car in front of the seats and you will be in SM2.

Yeah I was going to say, wouldn't it be SM2 instead of SM?

Well technically SM is both a class and a classing level, just like Stock, Street Prepared and so on, so what was said is correct.
