I changed back for a month to OEM suspension Nords and tbh it is a very well put together bit of kit, especially those Sachs shocks

on the road it is very good

Have to say I agree .. . I am contemplating on going back to OEM setup (actually have started running stock rear springs already ) and this is after a number of years on the AC Schnitzer setup.

Last track day gave me the opportunite to go for a ride in a completely stock standard CSL and fXck me I was impressed with how composed and well balanced the stock system was (I have long forgotten what the stock car felt like) - whilst it wasn't as quick lap time wise, it was certainly lot more controllable and predicatable - also seem lot easier to slide around and catch if one felt so inclined.

I've honestly hit a wall with my current setup already and have not made up my mind what to go to next .. the stock system is hard to beat - I might get one of the local Koni outfitter to valve a custom double adjustable for me based on the stockers but with upwards tunability.

Cant beat OEM for the road, we dont even try.

For track there are loads of options now, some good, some not so good, some with warranty, some with none, choice is yours. Personally I find Intrax too hard for UK's roads, KW hard to recommend with no warranty, Nitron very good, Moton stunning but very expensive.

Oh and looking at race cars as an indication of choice can be a little flawed, there are lots of race cars with a sticker on but others suspension (ask Andy Priaux - 3 x WTCC Champion on Motons but stickers from other on the car all three years). Some suspension manuafacturers are very agressive here, lots of free kits offered to lots of race teams = lots of suspension on cars. Free does not always = best. We pay full whack for the Moton and Nitrons on our Cup cars, bloody expensive but worth it. Moton do now do a road/track kit, single and two way adjustable.

Interesting that you find Intrax 1k2 too hard - they can be set softer than OEM with appropriate spring rates. The whole point of the Intrax & Ohlins philosophy is softer spring rates and better damping to allow you to take loads of kurb without upsetting the balance of the car.

Motons are very, very good, but a different price bracket all together than the dampers being talked about here, Ohlins TTX at £4k+ a corner is also awesome and just as relevant to answering the question

Different horse for different courses I guess, I tend to go by what I'm asked to achieve. In the last few weeks we've have 2 CSL's and 1 M3 with Intrax on and the owners all wanted a more 'progressive' ride and more grip from the rear. We softened it up as best we could and it did improve both the ride and the rear end grip on the road but each came back and said after driving it on their own roads (MK is pretty good road wise) that it was still too hard. Certainly my test route home starts off on smooth MK tarmac and a track setting on KW's/Motons/Intrax all works well, but the moment I get to the crap B roads near where I live and all but the Motons leave the ride near on impossible to live with, hence a compromised set up is needed. IMO Intrax dampers are set too stiff in the range but one mans meat is another mans murder.

Motons have come down in price a lot, road/track single adjustable are now £2600 down from £4k from a few years back but agree they are above everyone else in terms of cost. C'est la vie I guess.

What spring rates were they running on the rear and what rates did you try?

Interesting that Moton have come down that much, thought they were still silly money.

Three different rates on the three cars. I'm sure we could spend more time on it via softer springs of course but didn't have the chance as each car was booked in for a single day. Intrax just have a different view on things thats all, Henk likes to run stiffer damping and softer springs and we tend to prefer the opposite but its horses for courses. We run very stiff springs in the Cup cars to the extent that KW and even Moton said they were too stiff but they seem to work pretty well, we run softer damping as a result and it means the cars run kerbs well which is a similar requirement to road cars running on bumpy surfaces.

Any idea of what rates? Interesting for me as I honestly found that when I was running a soft spring rate on the rear there was more traction than with OEM suspension, you could feel the weight transfer to the rear of the car which just isn't there to the same extent with a stiffer rear setup.

That makes sense, we found with the spring set up that there was we softened it up as much as we could on the damping and it improved but we couldnt go far enough, hence we thought the springs were too stiff. I've got them written down on the job card will have a look.
