35W AE / 2 Hole 1.6 / Progressive springs / Stock Swaybar

Rear:
35W AE / 2 Hole 1.7 / Progressive springs / Stock Swaybar
5K Diff / Holeshot M3 / Proline Closed Cell

Everything else stock.

Good for 22.7 which is her personal best with this setup

Hi.
Nice track and impressive driving.

Have you tried stock linear springs? What are the benefits with progressive ones?

Btw. your 2x1,6mm piston is the ~same as 3x1,3mm. I've calculated mm^2 for different pistons..

Don't know how much there is traction, but IMO the PL closed cells are way too stiff. I'm running AKA reds. Give those a try?

Yes stock linear and 3 dots linear (stiffer) have been tried

The progressive springs allows us to run a bit softer and with a lower ride hight and still not experience too much chassis slap entering the wall and a few of the jumps.

We have 3 x XB4's so changing setup and doing adjustments are fast and easy, just swap in newly built shocks and go.
Back to back testing are the best approach

I also have shock drilling tools ranging from 1.05mm up to 2.00mm in 0.05mm increments.
Right now I have pistons made up in 2x1.5, 2x1.6, 2x1.7 in addition to the stock pistons.

Tested pistons so far are 2x1.4, 2x1.6, 2x1.7, 3x1.3, 6x1.0 and 6x1.1

We have full spring sets and sway bar sets ranging from 1.0 to 1.4 for 2 cars.

As well as the optional 6' c-hubs.

Testing continues until we don't see any improvements.......1 change at the time.

I prefer the feel of the Pro-Line foams once broken in (usually after the first set of tires wear out).

We also have the Red AKA's, and the new JConcepts Medium and Firm inserts which gives the tire a slightly flatter profile.

So far the Pro-Line's are the favorites for the choice of tires ran here.

3rd race night and I'm now convinced this buggy can handle some abuse! My spare parts came in so I was driving it harder last night. (not the upgrade parts)
I'm using stock diff gears and they still feel great. I have the slipper even looser than spec, maybe that's why it's still holding up. Running on med-high grip astro indoors.

Only mods I've done are an aluminum upper brace for front shock tower and camber link brace on rear tower.

I've TQ'd 2 of the nights, and won 1

I drove my XB4 for the first time yesterday everything felt good.

I do have a set up question though.
My front toe changes dramatically when my chassis goes up and down.
I have never had a car that did this before.
Have I done something wrong in the setup/ build or is this supposed to be like this?

That's called bump steer. My car doesn't have much at all. Make sure you have the washers under the steering ball studs.

It isn't the washers. I did the same thing. You switched the left and right sides...those things shaped like a 'C'. I'll see if I can look up the part name...they look identical...but you're seeing what happens if you mix them up

Alright kids, I've decided to pull the trigger on this kit.

What's some of the things i'll need straight away. Option Parts? Besides arms and such, which spares should I purchase?

you don't really need too much. the upgrade packages should be out real soon so that will take care of the front bulkhead and a couple of other things if you should have that problem. When you get it together let me know and I will show you what I've figured out for setup at Leisure. Gonna do more testing this weekend.

Get a spare set of outdrives, I broke one before I realized I need to limit uptravel on the shocks.

Once you have the upgrade kit you don't need anything. Of course different shock and diff oils are good to have for tuning. Get some spare wings too.
