No these blocks had 3 holes and no special markings. However, when I put the 7922 part in, that camber block leaned back much more the then original, or the unmodified side, for that matter. To the extent that the arm on the steering block touches the a arm when the steering is maxed out. The part that came with the kit has almost a quarter inch gap for the same condition. Doesn't lean back as far.
So, I'm not sure what came with the kit then. All I know is there is a big difference in geometry after installing the 7922 30 degree blocks.

They are installed right.
I could definitely notice the front of the block higher on the 30 degree side. You could not see the front of the block on the original side. Probably a difference of an eighth of an inch, or less.
I think this was just a parts mix up.

Getting a used car with the JConcepts hexes. I plan to run it a day or two after it arrives so trying to plan for it ahead to use my pin/bearing wheels.
I just got the motor (d3.5 17.5 maxzilla version) yesterday and was playing around with it today at this track...

Didn't quite finish tuning but ended up at 72/33 with full timing (20 on can... which is supposed to be 50 on this motor). No ESC boost, etc.
At the end of about 10 minute run, motor was only 113F (ambient around 80F). (Probably will go another pinion, maybe change spur down to 69)

The track I am running on has a double in the center of the 70' straight that you have to lift for not to throw the car funny and waste the landing. The rest of the track is very tight, not much for high speed areas to speak of.
We are also running on carpet with MC Suburbs front and rear.
Traction is insane.
So....
That is why I am at 75/33.
Also,
You should be able to get to the 25* mark on timing or close to it.

That motor will handle 36-72 no problem. just keep going up and checking temps....... run it 3 min, check temp, then run it 6 min, check temp. If you do 10 min mains, run it 10 min and check temp. You may find that you need to go down 1 tooth for 10 min. Then again you may not.... you have to test.
Ok for the front you would need the stock steering blocks and front axle to use the bearing wheels, and the rear you can just simply remove the hex adapter.........

I didn't snap it, I was switching rides with one of those "losi guys" for a few laps... He wrecked it pretty hard a few times. I will say though, being the first time I modified the wing mount I did dremel off a bit much, the next one will be much stronger. His buggy felt OK but it was good to go home with the b4.1!

Just Found a awsome way to put the bb shock rubbing up against turnbuckle problem. It's a $4.00 fix that can make you shocks 1 look good also can get rid of all play what's so ever in the rear. It's the plastic rear hubs for the b4.1. Since they come unthreaded you can put the ballstud in whichever side you want to i decided to put them in backwards and place the turnbuckles backwards and also buy buying these hubs means you can get rid of all the slop since you don't have to use the aluminum ones anymore that slop out after about 10 races.

Found this info:

============
Separate, but related...
Which one of these is used on the Worlds car?



Need to buy these parts before my used B4.1 WC comes so I can use the B4 style wheels I was using on a TRF201. Also not sure if people are using inline or trailing axles? I see both listed as parts.
