Don't forget cheaper shipping too! I had my buddy and local shop owner order me a few things from RCA and they totally bent him over on the shipping to the point I actually felt bad and paid the shipping costs too. If you can wait a few days RC Mart is another great place to order from and killer pricing and super deals.

I am looking to try a battery mod. Seems like the reverse of what they did would be much better.

Not sure what your mean on battery mod... reverse of what they did..
Are you talking about moving the battery to front of car?? that would be too front heavy then.

Either way, "...reverse of what they did would be much better" isn't a phrase I'd use on the XB4.

Having traction roll issues in and out of corners. The rear of the car lifts up and the front dives when come into a corner on breaking. What can I do to help this from happening. It's the 2015 XB4 being run on carpet and turf.

If so it sounds like your front shock package is to soft. Go up oil and spring to prevent the car dumping on the outer front corner.
With the harder front shock package, use rear toe, roll center, sway bar to gain back the steering you need.

Are your front tires the same as the fast guys at your track? Glued side wall? Remove outer row or 2 of pins?

Are you using modified springs where you cut down the one coil to get to the 14-15mm ride height needed for carpet?
Most guys and team drivers I believe are using the '16 3 Dot Front and 2 Dot Rear springs and cut 1 coil off, since the spring rate tends to be better than the shorter carpet spring they made for the 17 & 18 model.
Also your gonna want to run heavier swaybars front and rear like 1.6 or 1.8s, I ran 1.8 front and rear and no issue car felt great.

Has anyone weighed the three different wishbone options on offer? Interested to see how much of a weight saving there is from stock to the "graphite" option. Is there a big difference in flex between them, feel by hand I mean.

Put the new 2.5mm alu chassis on my car last week for high grip carpet. OH MAN what a difference it made! If you race on high grip carpet the chassis is expensive but it really brings the car alive! Easier to drive, more corner speed and more consistent.
