Ya it looks good. As long as the price point is on par should sell good.

Quick question. I am considering changing to 48p gearing. My TT-02R came with a 68t spur and a 27t pinion in mod 6. Can someone tell me what would be equal using 48p gearing?
thank you

Your best bet is to pick up the Yeah racing motor mount. Then you can mesh with ease.

I'm hoping I'm the only one that is having a problem with this. But I've noticed that in the last two Yeah racing motor mounts I bought - the radius of the arc opposite the pivot point that the motor screw goes through is too small - The result is that the motor screw hole winks in the slot - forcing the locking screw to cross thread on an angle into the motor - NOT GOOD - fortunately I have access to machines to fix. I'm not sure if the issue is with the Brushless (Fantom) motors I use? A bad batch of motor mounts/. Buyers beware!

Had to make a jig and mill the two edges of the slot - you can just barely see here where the anodized is cleared

I bought two of those Motormounts and had exactly the same problem. I had to grind some material off to make them fit.
Also with the TATT-034 Anti-Roll Bar Mounts I could not get the screws in the the Tub Chassis. The holes in the bracket seem to be 0.5mm to far outboard on eighter side. So elongated holes where needed.
With the Lower Arm Mounts TATT-028 and TATT-029 I could not push them all the way in X till they sit against the Tub Chassis. The tab for the bottow Z-screw seem to be slightly wider then the humps on the chassis below the differentials. So I have to shave some material eighter off the chassis or the aluminum mount.

I get the impression that somebody at Yeah Racing does not know how to use a Caliper. 😣
(Not to mention the Long Span Suspension Kit for the GF-01 / WR-02, making it fit was a nightmare.)

I also had the fitment issue with the Yeah Racing motor mount, but it only required a very minimal amount of massaging to make it work. I did buy the PSM mount, but haven't tried it yet. It looks to have a much larger motor positioning range.

Much larger? Looks the same to me, just different color.

I’ve recall a motor that would not line up properly a few years back.. don’t recall the brand. Could have been a fantom as I used to run those

I haven't measured but to me its definitely larger in the photos. If you look at the width versus the screw holes at the bottom it seems to indicate the PSM is larger. Maybe my use of "much" wasn't ideal

Ah, That's clearer, I see it now - the center opening is a bit more oblong, looks like they managed an extra degree or two at each end...
Either way, its too bad Tamiya hasn't made an adjustable piece like this.
The fixed unit can work, but you need to "trial-and-error" to figure out which combination of 64p spur and pinion works for the various hole pairs.

Question about Tamiya Datsun 240Z bodies- have a TT02 and they have two bodies listed One says TT01 - will this body fit the TT02?

Yes. You will need to flip the lower and upper
arms for the shorter wheelbase

So, to answer my own question. A 68t mod 6 spur is approx 41mm diameter. An equivalent diameter 48p spur gear would be a 78t.
To match the final gear ration:
Mod 6 - 64/27 = 2.51
48p - 78/31 = 2.51
