I am parting out my 1990 S13 Fastback 303 whp SR and have some PBM spacers installed. Also have 50mm Nismo Wheel Studs that I had installed on my G35 last year but removed when I sold the wheels and the car.

PBM Hubcentric Spacers - All for $100 plus ship
15mm (4x) - $110 plus ship
Rear 3mm - $20 plus ship

Nismo Long Hub Bolt - 12x1.25 - 50mm - $45 plus ship

 

Could you do me a favor and tell if there was any slack at the hubcnetric ring? i have a set of spacers that have very small amount and im not sure if its safe.

 

There isn't any slack between the hub and hubcentric ring. The tolerances are pretty tight providing good fitment. All PBM products I have owned are top of the line. (Tension Rods, Traction Rods, Fender Roller, Cobra Flex Downpipe)
