I bought the quicktread black side steps from JNK2000 Ltd, they are fully rubber encased and look fantastic. I was going to fit them myself but as they are made about 9 miles from me I popped along. The business owner, the chap who designed them and manufactures them, said they will fit their products for free even if they were bought from a dealer.
These are the steps Urban supply, he supplies them and several others.

The fitting took about 15 minutes, absolutely no cutting to the vehicle, no trim removed or modified, they just bolted straight on.

I am really pleased with them, they look great and have a real quality look and feel to them.
