ran mine on carpet Friday. I went from a 17 xray to the 20. So it drove very different. I have driven 19s and the 20 drive very similar to those. Has a ton of steering and great rear grip. Very happy with it. Only build issue i had was they sent two sets of rear springs instead of the front and rear springs. I put the 3 dot from last year's model on it. They are longer but worked until i can get the correct ones.

Are these aluminum towers low or high?

Will these work good with my shocks? I have a xb2 carpet ´18 , currently using the high towers.

High bite carpet. Mid to large track. Long straight, tight corners and some good jumps. Prisms on rear, Schumacher Low Cut Stagger on front.
Had practice time Friday and a points race Saturday then a little practice Sunday.
Buggy was pushy with box setup.
Changes: Moved servo all the way forward. Battery all the way forward. Added battery and servo weight. Moved rear hubs back. Put in 2.5 caster blocks.
Result: Was much better. Switched to Prisms on front. Was better. Turned some fast laps.
Next: Rear anit-sway bar, less rear toe, Ackerman.
Overall: Buggy handles very well. After changes it was much better. Compared to my 19 it has more mellow steering. My 19 turned on a dime at 80% DR. I have this one at 100% DR. Never ran my 19 on 100%.
I feel it needs more steering. I will be trying the above changes.
To be continued....

I'm not an expert by any means, but that's the concern I had as I saw the changes on the rear arms to the 4wd on 2020... maybe a little too much rear traction on power? I got that from testing the same thing with the 18.
I ended up get the 19 for a steal, and I'm very happy with it. Such small changes from 18 to 19 made the car a lethal weapon on astro for me, box stock

On the 20 I started out the same but ended up with Prism front and rear in Z3. Right now the 20 just doesn't have as much steering. DR is at 100% still. Working on that.
Just added rear anti-sway bar so we will see Wednesday. One step at a time! lol!

Update: I had a chance to test a little more last night. With the added rear anti-sway bar the car was not as good. Wanted to traction roll and didn't feel as planted to the track. Removed and was much better.
I did try some wide front Prism. They were OK but sticking with the narrow. They have more steering. I now have my DR down to about 85%. All in all I think I am pretty good now with the major changes. Now I will try some of the usual small changes to see if I can get a bit better.
Always looking for those tenths! I feel it is as fast as the 19 but is easier to drive. More mellow.

Does anyone by chance have a list of all the hinge-pin lengths? I looked through the manual and parts list, didn't see any specs for them.

Playing more with my frankenstein xb2c 19. i first started with AE B6.1 front gullwing arms. Switched over to Yokomo YZ-2 front gullwing arms.
I found this online tutorial on flat vs. gullwing arms and so far in my testing I've found this very accurate for the xb2 on the topic
The gullwing arm tends to:
1) less forward weight transfer off power
2) less likely to snap roll at end of straight
3) usually can push more in tight turns, good for laydown car which has weight forward.
4) I recommend using more antisquat with gull front end
The flat arm tends to:
1) more entry steering off power to get into the turns
2) better with stand-up gearbox, more steering
3) can be more likely to snap roll on super high traction
4) have the same arm left and right, easier on spare parts
