A wheel PCD is made up of the number of studs that hold your wheel on, and the diamater in mm of an imaginary circle that goes through them all
So 4 x 100 would be 4 studs with a circle diameter of 100mm.
If you're not sure of the PCD of your car, just ask us and we'll be happy to help
Firstly I'm congratulating the customer support and the importance Driftworks has on getting the info about the car and fitment. I knew I'd have fitment issues and I was informed about that. After rolling, camber kits and coilover steup it's amazing as you can see in the pics below.
