Hi Sean, If you want to be able to do real low profile stuff have a look at the Corghi Artiglio master.
While it is big money, it is brilliant. It doesn't use a main arm, which means no chance of marking up alloys. I have seen it in use & it is terrific. You get what you pay for. I was so impressed that when we renew our changer, this it what we will go for. Price of the tyres may have to go up to cover it though
I think they are marketed by Apaseal in this country, but the link for corghi is below Just select automotive, products,changers, artiglio master.
