I have a set of four centre lock 15'' J7 genuine MiniLite wheels used only for track days therefore probably six - eight days use in total. Currently black painted with the Minilite chrome centre.
As my Morgan runs 16'' road wheels I put 225 55 r15 track day tyres on the rims to keep the same running diameter. 215 60 or 205 60 will also do the same thing.
Can't remember how much I paid from MiniLite but todays price for these same wheels is £322-- each. I am looking for £700-- for the set, therefore about half price.
Send me your email if you would like some images.
