If like me you’re keen on fitting tasty wheels to everything in sight, then you might want to get yourself one of these handy, telescopic PCD measuring tools. This is a dead handy thing to have when you’re at a swapmeet, or down the scrapyard, as you can instantly check the PCD of any 4, 5 or 6 stud rims. In some circumstances you can also flip it over and use it to measure the studs on a hub, but only if the hub centre doesn’t protrude too far. I picked this up at the NSRA swapmeet for a fiver but you can go to Bialbero Racing and order one online. There’s more info about this neat little tool there too.
