A spool help the car to turn in on entry but can make it a challenge to drive on exit. We still have a ball diff in my son's WGTR. The spool is too much for him as he is learning. We use 30k Kyosho diff grease and it seems to keep the inside wheel from slipping on exit and is closer to the spool on entry.
I used to, by accident, run my GT12 diff so tight that someone called it a spool. Don’t know how/why that would be better since on the GT12 car I could see it lift the inside wheel every turn.
For now track has lost me to off road. On road is practice only or last resort racing

Anybody know how many millimeters of axle spacers to run on each side of the pod, on the Crc car?
Left mine apart so long I forgot.

I usually set the car on a set up board or a ruler and set the total width to between 195 and 198, depending on how much rear grip I am looking for. Is there a center dot in the lower pod plate on the CRC? My Roche has a center dot there that can be used to find the center of the 195mm.
Have a center dot, but it's a long way from the hub to measure accurately.
I just lined up the seam in the tire with the body mount holes. That'll have to do.

He's got a point.
Tires sticking out should be illegal. And those decals on the inside of the body for weight, arent applied to the roof.

I am just mounting a new Akura and it doesn't seem that far off the other bodies that I have.
Rear fender to fender:
Akura 191mm
Protoform C8 191mm
McAllister Mustang 192mm
Zoo 193mm
Protoform C7 196mm
In my opinion, the issue isn't with this one body, the issue is with the rule. It is nearly impossible to enforce. SCCA full scale ran into the same issue. Tires must be within the fenders, but guys just pulled the fenders out by hand to make them a little wider and since there is no factory spec for how wide a fender is, there was absolutely no way to consistently tech for pass/fail. The rule said that it was to be measured by using a plumb bob from the upper most curve of the fender with the car placed on a flat surface. Flat surfaces were difficult to find and could be disputed. Guys pulling fenders with no way of truly measuring could be disputed. A rule that cannot be measured easily into a pass/fail situation will be impossible for tech to manage.
My car currently sits 195mm width. I have run as narrow as 192. The Akura fenders look pretty close by eye balling from the top, but with no defined way to measure it, we could argue all day long in tech at the subjective nature of the measurement. Or, if I wanted to, I could bend the rear fenders out a little at the seam at the top of the fender. Who's to say that I didn't get one from the factory that measured 194 or 195? There won't be any crease showing - it's just a little bend. If I run my Zoo, which measures 194 and my car is 195, am I going to get bounced in tech? Or would I be allowed to grab the second one that I have that measures 195? So what is the official width of each body on the list - do we need to have record of that in tech from now on?
The only way to have an enforceable rule is to set a minimum and/or maximum track width for the class, just as SCCA has had to change to. There is an easy way to measure pass/fail using a roll-through box. Today's fastest bodies are all between 191 and 196mm. I don't see any harm in having a 195mm maximum track width and letting rear tires stick out a little. Maybe some cars cannot get than narrow, I don't know. I have an old CEFX car that cannot get narrower than 197 with a diff, but with a spool, no problem. As stated, I don't have an issue with the Akura body, the issue is the rule itself. But reading this thread, I'm not sure others have as much of an issue with this body being on the list than issue with other bodies not being included. Maybe there is a better way to lobby for other bodies to make the list?
Here is the exact rule as written. "Tires cannot stick outside the body." As measured from where? If I look at the Akura at the front of the rear fender well, my tires are well within the fender at 195mm. It is a subjective rule that cannot effectively be enforced.

[Puts an MXstang on his Crc]
Not sure that was a great call. I wanted to run the Akura. But if ya'll are already running it, I'm going back to the McAllister Mxstang to be different.
Almost done with the rebuild. Four tungsten weights, two steel weights, the heaviest battery I could find, and an AL cased ESC.
915 grams. 15 grams underweight. Only missing my transponder (4g?).
Going to have to call this build, the lead sled. For all the lead stuck to it.

Don't know whut ya'll talking about. Akura fits perfect.
Bought one for Usgt. It's 106g uncut. Maybe it belongs on my Wgtr? But it sure looks like a cheater body.
