on set up i cant really make out exactly how much caster i have im going to take a guess at 2 degrees ???
Looks to be around 2 maybe a little less

To check tweak I measure droop and ride height. Then I do the center lift to make sure the tires go up at the same time. Make adjustment by loosening or tightening the spring collar to get both wheels to lift up at the same time. After I get everything perfect I notice for example front left is 0.2mm higher than the front right. Is this normal? Does the ride height need to be exactly the same from left to right?

I tend to measure ride height on both side,s as near as I can get to the droop screws, using a stepped Hudy gauge.

This should get you very close as you're automatically compensating for weight distribution etc.

to check tweak ,make sure all screws under the chassis are flush,take off wheels and place the car on a sheet of glass,if the car rocks from side to side then the chassis is tweaked,keeping it on the glass undo all the top deck screws and then retighten,check for rocking again,it should be gone,then set your droop and ride height,if your car isnt balanced then your not going to get the best from it,so it is important to get side to side balance spot on,front to rear isnt as important as side to side,but a 50/50 side to side and a 50/50 front to back is preferable for the best handling,without this settings will never be spot on,all shocks should be exactly the same length too or that could cause one wheel to lift more than another,once set pick up each corner at a time with wheels on,lift one corner until the opposing wheel just lifts,front left wheel should lift the same amount as front right wheels the same applies to the rear also

it was the only car i didnt get to have a look at to help me choose my next car,
I fully understand what you were saying about the pit tent, but in their defence I don't think the weather helped.
With the wind coming from the trackside in the direction of their gazebo, they had the sides up to shelter them.

My best setup for asphalt was with 2.7 front and 2.5 rear springs with 350 cst oil all around.

What base setup did you use? Did you follow a factory driver setup or the basic Xray setup?

Norcal Hobbies - Using Losi 32.5WT all around, think its something like 400cst equivalent. 2.7 spring front, 2.5 spring rear. Running 50% rebound. Actually did not like how 100% felt.

Car is super planted and a slint hint of push, but very stable.

Thanks for the tip guys ...

How many use the lift method or the hudy tweak station with the bubble?
I have 4 scales but find it difficult to use as the numbers are sometimes off

I started with the the kit set up but found the car to be too stable. I needed more rotation through the corners. So I installed the 2.5 springs in the rear. 1.5 degrees camber front and rear. Zero shims under the inner front camber link with 2mm under the outside front link. 1 mm under the inner rear camber link and 4 mm under the outside rear link. Kit wheel base. Droop is 6mm front and 5 mm rear. Kit track width.

Note: traction was super high.
