You want to remove the axels (they are hollow) and the use axle nuts and not the quick release. That set up is for road/touring bikes and not suited for BMX racing/jumping.
The hubs you want are Campy track hubs (in you want the Record hubs) with solid axles.
You can get the axle sets (includes axles, cones, locknuts, and axle nuts) from a store like Business Cycles in Miami
Unless you are a stickler for ONLY Campy parts, I would reccomend the aftermarket sets. They run about $50 for front and rear set ups. The Campy axlenuts alone are about $24 EACH!
They are easy to swap out as long as you have the cone wrenches (I think they are 14 and 15mm) you should be able to get them at any local bike shop or go to Dans and get Park wrenches.
