Fronts a lil hard on S13 just cuz the fender wells a lil smaller than the 14. Youll have a lot of banging to give you room full locked. I was running 17x10 +12 all around. Depending on the suspension and how low/slammed it is, youll need atleast an 8mm spacer effectively making the front into a +4. As far as your rear, just cuz they were 50mm fenders doesnt mean they are sitting 50mm exactly, so cant tell you how much spacer to run. Figured atleast a 25-30mm spacer and it should be close enough. Also, with the rears, itll depend on size tires. Front, no butts and ifs, you gotta go small. I was running undersized tires (in reference to stock diameters) 235/40 17s. Helps with full lock turns, keeps the tires away from the inner fender well and from eating the wheel well harness boot.
