Thanks for your replies ! I'll go to the local hardware store tomorrow and find some sheet metal screws.
I have just been informed that 6 screws on each side of the rim proberly is'nt enough acording to National
Dragracing Club Denmark rules ( same rules as in Sweden).
Thanks for the hint where to find the Screws on Summit Racing's website, they call them rim screws, I searched
for slicks screws
. Good PDF file with instructions on Summit's website.
