That was my experience as well.

Just tried some team durango pinions and they fit much better. Problem solved.

Thinking real hard about racing dirt. Absolutely love my xray t4 15 for on road. Thinking about staying with xray xb4 . Question is this, current owners would you buy another or maybe something else ? I see comments about what a great car the 413 is,but to fix steering use the xray parts,etc etc...I s the xray adjustable enough to run on loose dusty tracks..or is it a car that is only good on a perfect track ?

The xb4 15 is an amazing car and great to wrench on. The 413 is a bit sloppy and not very easy to work on. I've ran my xray 15 shorty pack on a variety of track surfaces from low bite loose conditions to high bite clay and with minor setup changes the car works excellent no matter what surface it is on. It should be a no brainer honestly. I would and will be buying another Xray car.

From what I have read the xb4 will run on any surface and do it with grace with the right setup. I let someone that use to be a pro run my xb4'15 and he could not believe how awesome it was. It's definitely the right chocie.

I hope I didn't miss this, as I read through a lot of this thread, is there a chart that shows what hexes to run with what rims? Id like to run the AE style rims, the new 2.4/60mm stuff is coming with larger front hex, so 12mm all around correct? I want to keep the offsets stock.

Excellent question. I was thinking the same thing. Getting closer to picking up one of these. Hoping to take some laps with one this weekend to see for sure

Exotek 12mm hex converion. Use the 7mm wide rear hex for ae offset rims and fronts use kyosho offset rim. Exotek also makes a 9mm wide rear hex not sure what rims those are for maybe kyosho.

Also Avid makes 12mm hex spacers down to .5mm wide to fine tune the track width for different conditions.

Is there setup sheets anyplace to show a baseline setup? I just got a used XB4 2014, and want to try it out this weekend. Any upgrades I should make sure this thing has? Anything to look out for?

Yes, I know, I have a lot of reading to do. I'll catch up sooner or later.

I ran the Tyler Vik setup on petitrc all last year on tracks from indoor clay to high bite sugar and it was dialed. Only changes I made were to ride height and steering dual rate.
