My understanding was that Ohlins "Road and Track" was very different than the motorsports based products. Per Ohlins own website and what I'd gathered, I'd thought that R&T were:

1. Single adjustable ("Damping rate on the R&T units is fully adjustable and ties compression and rebound together as a matched setting")
http://www.roadandtrackbyohlins.com/...hlins-concept/

2. Use this "Dual Flow Valve" system ("The new Öhlins R&T range uses DFV technology on every single fitment"). http://www.roadandtrackbyohlins.com/en/the-technology/
The DFV pics in the link look a lot like a regular shim stack, etc, but with the added orange bit designed to increase the digression at high shock speeds?

3. Less expensive and designed for street use. They are street legal, tuned for more comfort on the way to the track, and do not need rebuilds as often.

4. Lower performance: given that they are single adjustable, probably have higher seal friction to enable the longer time between rebuilds, etc, I assume they can't match a motorsports based kit. They come with springs they are matched to, so you can't select and tune your own spring rates.

All of which adds up to something that like shock for the E90 BMW 3 series in this PDF:

http://www.roadandtrackbyohlins.com/en/product-range/

So I thought I'd understood... Then I saw these, also listed as "Road and Track" for the GT3 RS:

http://www.roadandtrackbyohlins.com/...he_gt3rs_1.pdf

That's obviously the motorsports based shock. It says double adjustable, etc. But it's sold as "Road and Track"...

So what's the deal? Is "Road and Track" just a marketing name, or are there actual difference on those TTXs that make them need rebuilds less often, etc?

Just as important, what is Ohlins working on for the 1M, one of those TTX based solutions (which I have to assume will be more expensive at least) or something like the other R&T shocks (single adjustable, etc)?

The TTX based solutions that are currently available, is there anything that can be done to make them more "streetable" (primarily meaning longer time between rebuild)? Those systems run around 5k, I'm guessing, if you go for the less adjustable versions?
Yes, it is pretty confusing as the Porsche damper is a TTX unit, essentially a race product. Same goes for the Lotus. Both of those dampers are race products which have been approved by Ohlins Sweden for use on vehicles which will see street use. Only product that has been approved by Ohlins Sweden can truly be classified as a "Road & Track" product. As I understand, the kit that Ohlins USA is working on for the 1M is not TTX based.
