The rear shafts will bend much more easily that the front. Replace the stock front cvd's with a set of ecs's. Xray has the ones that I have been using but companies like rsd have great options as well and they are less expensive.

Yes, we will try the 550 oil to see the difference.

In Luxembourg Hagberg/Coelho used 550 oil, and I was not aware at that time that they were using PSS.

400/450 worked better for us in Luxembourg, using "normal" dampers.

The RSD ECS for the T4 are a direct fit, but they use a 3mm inner hub bearing (and come with the bearings). I use them and they work well.

You can also use Tamiya DCJs, but those require different outdrive cups.

I used the PSS this last weekend on a bumpy large asphalt track. On a hot track, you will most likely need to go even heavier than 550. I ended up going back to the standard shock as I felt more comfortable with them. Next time out I will have 700 weight oil in the PSS and see if that is good enough for the Texas heat.

Please correct me if I'm wrong.
I thought I read the best part about the pss is you don't have to change the shock oil and that they self adjust as they travel.
I thought they were to eliminate the shock oil worries so you can focus on the suspension?

You're still going to have to find the right oil for the situation.
I certainly didn't think they were going to be aq miracle cure for suspension woes.

I now have some and will be testing on carpet and then on asphalt at the weekend.

Nice, I am waiting for your experience.
I haven't seen this option part on any teamdriver setup so far, so I am a little sceptical about a performance advantage...

I'm almost positive Alex and the rest of the team have been using them at almost every race. They had them at Worlds last year and our car was really good.

No, like skidding said, the oil will change. I imagine 550 oil would work on a very smooth surface that is not very hot. Here in the states 550 is prob too light as it will thin out with the heat.

If you go to the setup section on teamxray.com you can see that most of the latest team driver setup sheets specify the use of either progressive shocks or PSS in either the "Shock" section in the setup sheet or in the comment field at the bottom.
