If you're doing a light bar... get something bigger than the Hella 500's...

I think the Hella 1000's are discontinued, but you might be able to find some in stock somewhere. Check

I don't believe the WRX shifter will fit in your car. At least Cobb's 2.5RS short shifter didn't fit in my WRX... the ball joint thingy is the wrong size.
Definately come out to a meet!
