Cannot understand all the broken parts.

none here broke diff-gears or something. Slipper settings were around 5.7 to 6.3, Tires were Mini-pin on high-traction carpet.

Especially the last day with many beginners on the track and plenty of full speed crashes on the straight was very extreme. Only part I was able to break was a ball-cup by landing upside-down on a vertically mounted board at a table.

Default xb4 fix!!!

guys i made some parts for mine sat. raced it all day with no problems at all. it will fix the rear shock tower problem and front bulkhead problem. i cant post pics yet. planning on getting a bunch made and having them for sale soon and cheap. just have to find a place that can make me a bunch cheap. trying to get the parts around the 35 dollar range for both front and rear fixes. will keep u all posted on the progress. As far as diffs. shim both sides of your diff at least .01 shims. steps on page 6 of the manual after u add the big washer that covers the o ring. add a .01 mm shim then put in the pin. repeat on the opposite side.
other than that car is awesome guys!!! i let our fastest guy drive it and he was faster with this car then his own. plus track was at it worst of the day. we water our indoor track between rounds. he drove it about a hour after racing had finished for the day and track was super dry. still his fast laps and normal lap times were faster than his car.

Default TSR SHOCK TOWERS WORK

I ran my TSR towers today. I took 2 tumbles that would have broken the stock towers, came out unscathed. I did wind up putting the NT1 gears in the rear. The car feels solid now.

Has anyone tried doubling up on rear shock towers? Would it fit?

yea well that lasted about three laps and I had the hammer down the rest of the time. 2 runs, uber smooth, drove like a winner from the get go. It's not perfect but it is damn nice. My first Xray but not my first 4wd (Dogfighter!) and I've had a bunch in between and this one is to me a bit of a landmark. Time will tell. My ZX5FS2 is getting cheaper by the minute check the FS thread.

After waiting since Dec 8th, my XB4 is on the truck for delivery today! I believe I should have it buttoned up by afternoon tomorrow. I'm seriously thinking about skipping the NYE parties that I was going to to get it finished. I want to hit the track Tue.

are the kyosho big bores a direct snap on? I do not like xrays 1/8 shocks as well so I am going to put them aside. I am asking about the length etc, any special mounting instructions.

My theory is, knowing xray, the shock caps are tough as heck, as strong as aluminum, so instead of deforming a bit, all the engergy goes to the towers. Using thinner K plastic tops, I will test it out . On another note, think yesterday had the longest roll ever in my scte, swear to god it was rolling for around 10 seconds or so, so I will be a good tester for the xb4 :P

Yep, the car is very good. We put 4 XB4's in the A w/a respectable field of almost 40 wheelers. Kind of a bummer that 2 of us broke. Mine was the rear tower @ the camber link on the left. Scott's was the rear tower @ the camber link on the right. 2 diferent spots on the track. We were both qualified in the top 3. Not any major crashes, just landed on the rear @ a slight angle. I am even running an 8.5 turned down to 85% throttle(small track). Disapointing finish to a great weekend of raceing.

But I'm sure Xray will be working on it. However, in the mean time, thanks to TSR, hopefully we won't have much down time. Hope the 4mm tower does the trick!!!!!

The Kyosho bb's have both short and long tops and bottom eyelets, with both the tall top and the long eyelet these are the approximate measurements. No bump stops or limiters.Also one tiny thing, the xray upper mount bolt that is shouldered is fat so the Kyosho ends fit way tight.
Kyosho Xray
compressed length eye to eye 57mm 54mm
extended length eye to eye 76 76
shock travel 19 22
It looks close on the car and I am a big Kyosho big bore fan and as was dissappointed in the Xray shocks during the build, but I was impressed by their performance. The shafts seemed leaky loose when I built them but after running they were no leaks at the shaft and only a tiny bit on one cap.
I'm gonna keep running the Xray shocks.

fwiw The only other issue I had during the initial run was a tiny bit of a leak from the front left diff/bearing.
