I saw another posting saying you have to purchase parts from a 2017 kit to make it work but hopefully that is not the case.

Just to check
What height spacers do end up adding to the front rear suspension on a tyre diameter of 41.5 front and 42.5 rear to get a ride height of 3.4mm front 3.6mm rear?

I see that some people *cough* Brian *cough* are running with only one damper tube. I've never tried this - I take it you have to increase the weight of the oil, and that's about it for setup changes?

I would have expected that the way the tube behaves on compression would be different than un-compression, but I have to assume that this is not the case?

I've just ordered a P12, and I'm looking forward to getting my hands on it here in about a week.

I am thinking about getting back into 1/12 scale after many years away from it. I just started running the F1 Evo and am leaning towards the P12 evo as well. I will have to order parts since my LHS doesn't carry Roche and plan to carry extra front lower and upper arms plus steering knuckles and king pins in my pit box. The one part that I'm not finding anywhere online is the plastic piece on the outside of the lower arm. Are they available anywhere? I tried to find a manual online for the new car to get part numbers, but I can't seem to find that either.

Running 1 tube is no different feeling then 2 tubes. It's easy to over think it's effect. The reason 1 tube is used is because its common to run 10k or 15k with a spool on black. With dampening that light, in order to get the same effect in 2 tubes, you'd run 5-7K. It runs out of the tube causing it to be rebuilt more frequently. So....1 tube, twice the oil weight, half the work, same effect.

You would probably need just another .25mm shim additional to what the kit comes with in the front (which is a .5 and 1.0) and you'd likely need the .5 rear carrier plus 4 x .4mm shims sandwiched under it. Its pretty easy shim adjusting.

Ran my Evo for a few practice runs yesterday since the other 1/12 guys flaked out.

The car is very very very easy to drive.

Made a few changes that helped on SCRC's tight-mixed layout. Lots of hard 180s which I struggle keeping the car from binding too much in the turn.

Going up to 35wt oil and running the shock in the shortest position on the servo mount and top deck. Hopefully that will make it drive more out of the turn.
