My current wheel/tire setup on my Evo 9 is 255/35/18.

I am going to take my car to get the alignment done and would like some recommendations on the alignment specifications for my setup. Car is mostly used on the streets with the occasional drag/road course events once in a while.

 

If you are on stock suspension use stock specs. If not search around the forum. Common alignment is around -2 front camber -1.25 rear and 0 toe all around.

 

I'm not on stock suspension, I have coilovers.

 

Tire size is irrelevant to alignment in most cases; unless the car is stancenation and you need obscene amounts of camber to clear fenders, or the car is raced heavily and every bit of traction counts. Alignment really depends on driving style and vehicle use. If your rarely going to track it then I'd keep the camber around 1' (1.5'max). 0 toe in the front and a touch(1/32") of toe in for the rears to encourage the car to track straight.
