What this needs is a full competition conversion kit, carbon, aluminum and titanium. 

Can‘t have fun if a AE or Xray 4wd competition buggy is faster than my BBX with Torque Tuned motor 

Also needs a Kumamon edition, so as Im crushing RC10s and Xrays everyone will be too busy scratching their heads to focus!

I don't think there's a definite answer on that, someone on here mentioned a website said it was low profile, Tower Hobbies website says it's a standard servo.

On the BBX page on Tamiya USA under "Specifications" it gives "Low Profile Servo" as required to complete.

Looking at the design of how it's mounted, the fact that there's a Tamiya low-profile servo mounted in every video or picture shown of one in running order, and the fact that Tamiya's own website lists that, at least in my eyes, is pretty definitive that it'll require a low-pro servo.

I'm suspecting the mounting location is sensitive to the distance between the underside of the mounting flange and the "bottom" of the servo case. Looking at the official Tamiya image with all the panels taken off, you can see how it looks like the bottom of the servo is right up against, or very close to, the chassis.

I can't seem to find any detailed dimensions of the TSU-06 servo besides the overall dimension. I'm sure any limitations in size/mounting height/etc should be detailed in the assembly manual (which I am eager to see one of these days!)

It MIGHT be possible to mount a standard size servo with standoffs if you use a slim solid servo horn instead of the thick plastic servo saver, but that's just multiple layers of speculation on my part based on exactly 0 evidence.

I don't know....Those rear tires look awfully familiar. I swear they are from Radio shacks 1986 "off-road champ"

Oh yes, it is somewhat similar!

Just play it safe and get a shorty servo. Many are using this in their TD2 and TD4 builds.

May grab one of those, I think a steering servo is the last thing I need to buy for my build.

I've been using the SPT4412LV servo in almost all my Tamiya builds as of lately whether it calls for a low profile or not.   One of the forums (or YT..??) recommended these and so far I've been happy with them.    I use to use the 20K DS3218 servos (also from Amazon) but while they're powerful, they're too slow for the faster cars.   I'm planning on replacing the DS3218 used in past builds with the SPT4412LV to get the speed up.
