Hi guys i have the opportunity to get my hands on 5 billet 94mm stroker cranks for your rb30s. They're machined from core billet 4340 steel, they're virtually the same spec as spool imports stroker cranks which are proven cranks. Cost $3,000 each, does not include postage to your address work that out later. Will require 50 percent deposit before I order the cranks. If you're interested pm and I'll provide you with my details as this is my first post I think on the forums. Thanks Jure
