15" Mini wheels up and running

For about two weeks now I have had the mini wheels on the car with the 50 Bridgestone tyres and it has made such a difference to the car in terms of handling. I painted the rims a gloss black with a lacquer on top of that. The stock wheel bolts are machined down to remove the serrated tops to the bolts and to allow them to be chromed into the recess of the head of the bolt. I want to put a blue VW badge in the centre of all the wheels but as yet I don't know how that is going to be done mainly because of the difference between the front and rear hubs.
