Guys

anyone know what car my blank wide 5 drums have been drilled to.

its a five stud 167mm PCD

BTW - if anyone needs it, in a prev post Phil74Camper told us how to accuratly calc pcd for odd studd wheels - well it worked for me anyway.

thanks phil

"There's quite an easy way to work out the PCD of a five-stud wheel.

Measure the distance between the centres of any two adjoining studs (say the bottom two), then multiply that by 1.7013 to get the PCD.

The reason is that you can contruct a right-angle triangle between two of the studs, with the angle at the centre equal to half of 360/5, or 36 degrees. From the old trigonometry, sin 36 = y/x where y is half the stud separation and x is the stud to centre distance (the hypotenuse). Double the size of the triangle and you have the total stud separation and the PCD as y and x. So to get x, multiply the stud separation y by the inverse of sin 36, which is 1.7013.

Hope someone can confirm my old high-school trig maths - its a bit rusty!"
