1. What diff oils should I run? Right now I only have the 8000cst hudy oil from the kit. What's a good all around front center and rear oil setup? Something I can start with? If carpet and clay are much diff, what's a good setup for each for each surface to start? When is the slipper best to run?

2. What shock setup is good for clay and carpet? I usually run 2x1.6 front and 2x 1.7 rear, any recommendations for me to try? What oil for each surfaces should I start with?

3. I have both medium and hard side guards and chassis braces. Which composite would be best for all surfaces I run on if doable without swapping each time?
1. I run 7k front, 40K center and 5k rear for clay surface and it works great for me.

2. I use the same pistons and use AE 35wt front 3 line front spring and 30wt. rear 1 line spring for neutral feeling; 32.5wt. in the rear is i want more turn in.

3. I have medium side guards all around but I took out 1 screw underneath for both front and rear chassis for grip.

The car's set-up will also rely on what kind of tires you use. If your clay track produces plenty of grip, then I would run bar style tires in a soft compound. Iff you need more grip then go softer in tire compound. Good luck and have fun.

thank you!

the hudy oils come in like 450cst, is that the same as 45wt oil?

i was thinking of running 8000 60000 8000 for diff oils, would this work for all around setup clay/carpet just to start then i can adjust later?

lastly my clay is pretty high bite, most people run slicks when the track has been there for a while, second tire choice is electrons when its a bit looser.

so im thinking of running the hard compound stuff so i can run on carpet too.

also what are ya'll running for motor position? back or forward? i have both cenral drive shafts...

Go here for a conversion chart for oil and springs. the CST scale and SAE oil weight scales are different.

I run the stock set up with a few minor changes. I changed the oils to 37.5/32.5 in the shocks and 5/5/3 in the diffs. If traction is low I put the stock center slipper in. I also went down 1 degree in rear anti squat. I tried different combos of diff oils and unless traction is ridiculously high anything more that 8/100/5 is too much.

The plastic stock hubs = 4mm in case you ever need to know that.

I have the floating servo mount. I just ordered the hudy one that the manual recommends. Works perfect. Don't have the part number at the moment.

I've only ran it once so far. I think it did just a bit. I put a little dab of sho gu so it wouldn't rub the paint off.

Can anyone tell me if the XB4 2015 Chassis is suppose to be completely flat (besides the kick up end) or does it suppose to have a arch. I took apart one that I got on trade and the chassis has a arch in the middle?

When you run the 15 without top decks the chassis can develop a bend.

It's amazing. I had a motocross accident and have nerve damage to my right hand and the aftermarket adjustable trigger, drop down wheel and stuff have helped SO much.
