Yea mate I have found a problem with the wellers like , I know 16v calipers don't fit in 13 inch rims so already knew I was going to have to change them but actualy they did fit sort of the caliper went into the rin fine but the inside of the spokes were fouling on the caliper would have ment spacing the wheel off about 20mm so I have gone back to 1400 calipers/ discs not realy a problem on a car that's going in a straight line. I know your wheels are 15" but the shape of spoke is exact the same and flat like mine so I suspect you will have the same problem. Just a bit of advice that's all mate.
