How old are the Minilites?
Original Minilites were mostly Magnesium and were specifically designed as a a lightweight (the clue is in the name) wheel for reducing unsprung weight when racing. Magnesium degrades with time and so proper Minilights must be checked for integrity and weaknesses and are not likely to be useable after a period of years.
Of course, they have been copied by a number of wheel manufacturers over many years and the copies are made in much stronger aluminium alloys, but the original weight saving is lost and they are simply a styling exercise nowadays.
Stick with the steels and you can't go wrong. Personally I really like the Bumblebee colour scheme and would sell the Minilites.
