the Blitz type3 has a standard spoke design, and also has a spoke design for wider calipers. i'd recomend contacting
www.phase2motortrend.com, i know that they sell the Blitz wheels, and they could more than likely tell you for sure.
rule of thumb for a s14 with 17" wheels is 17x8.0 +31 (front) & 17x9.0 +38 (rear), i'd go with a 225/45-17 in the front and a 245/45-17 in the rear.
hope this helps a little...
