yes I have ran it once without a real setup. The front and rear lower arms are different but upper arms are the same.

Yep, I was looking up some spare parts, and the front and rear arms (upper and lower) each have their own part numbers, as do the front/rear hubs. Kind of weird, though - all of these parts were the same front to rear on the 4X (if you were using the active toe in the rear). I kind of wonder why they had to be different for this car.

It will be great to get a serpent but the lack of parts and support limits not only me other racers. Why serpent doesn't spread the distribution around the world instead of giving only power to one company who doesn't support neither promote the brand. Wake up serpent please... Hopefully someone from serpent can take care of this. Look at what other companies are doing. We want to buy your car but your short and poor distribution stop us from buying it.

Nope, on the P4Pro there were different, that was exactly why the car was easier to driver than the original P4...

Hmm, I stand corrected. I forgot when I built them, they have different part numbers. Just at a glance they looked the same.
Don't want to mix those up when working on them.

Did you find a setup to base yours against, or was that built according to measurements in the manual? Just asking, because that looks like a lot of toe-in at the rear. Then again, Based on the position of the links, it looks like it will open up a bit when it gets loaded up in the rear.

Race 2:

Another great day with the Serpent X20. I attended my local track which is a covered treated concrete track. The grip is low and normally goes to medium grip by the 3 heat. The setup I tried this week was the Chee setup I found. Chee setup sheet
The only change from the setup was I kept the 7000 oil in the diff oil and I put the rear gear diff in low position.
At the track with first few laps I felt the 1mm down stop was not enough because the car felt a little skatie like it was sliding on-top of the track in the corners. So I went up to 1.5 mm all around and the car felt very planted. In fact I had a push mid to exit corner which was my same problem last race day. (Even with the push I was able to get TQ and the fastest lap times of the day) So to counter this issue I tried a few things. I took 1 mm shims out of front roll centers and that had no effect. I decreased the rear camber by 1/4 and that had no effect. Last in the main I went with a stiffer spring in the rear (2.7- 2.5 progressive) That made my car 2 tenths seconds slower. I thought this to be odd the stiffer spring did not really help. My past experience this was a great change in my past.
So I messaged a Serpent team driver Felix Law which is a super nice guy and has been very helpful with his busy schedule. He mentioned play around with shock position. This is what I will work on next. If anyone has tested the X20 lately and have any advice please post up some suggestions.
Thanks
