John, I agree "black paint is black paint" but 10 years of testing and over 200 Delorean shock kits have shown me that "collars" are not necessarily always "collars," no matter where you buy them. And having a tax number and buying from industrial locations is one of those "been there, done that" things that never produced a collar that I found acceptable to use for one of my shock kits. And I don't quite understand the economics of buying some sort of industrial collar and then spending the time and money to "modify" it to the way you want it, but I'm sure you've worked thru the cost. All the collars I've ever supplied were custom machined from aircraft grade aluminum specifically for the shocks they went with and were designed only for this shock application. They were then inspected and checked for accuracy and then polished before being sent with the kit. Oh, now that I think about it, I guess I now understand your "black paint" comment, anyway......... And when you say "shocks in this category (soft ride) don't vary much except in color and brand" I don't necessarily agree. I've tested dozens of different shocks from different companies that are all within the same "category" and they all have different ride characteristics and qualities. That's the reason shock companies make so many different variations. But a lot of "ride quality" comes down to personal preference also, so you can do as you like with picking which shock you use. John, I'm not trying to get into a fight or anything like that over this. Like I said, you're free to produce any type of product you want and different shock setups for the Delorean is one thing owners have needed for a long time. The basic collar design is simple (altho you will find it's not as simple as it looks) and I'm really surprised someone hasn't copied it before now. Good luck with your new shock kit. What I do want D owners to understand tho is that this shock kit you are making is NOT the same as the "Touring" kit I make and it is also NOT being made or supplied to you by me. Your kit and my kit are two different, separate products that now offer owners additional choices for our cars.

I won't say they are common unless you are set up with at tax number to buy at industrial locations like I am. I can also buy them cheaper than making them and then were going to modify them to the way we want them. Actually when I bought them at the 2 locations, they were the same collars in 2 different packages.
