If your group allows different tires there are obviously a lot of choice. In the Tamiya Championship Series in the U.S. they allow the Tamiya type"A," Type "B," and Type "C" in the GT Pro Spec Class and any Tamiya 24mm or 26mm rubber tire in the GT Spec Novice Class. Obviously, there are a lot of good tires out there. But, if you are restricted to kit tires none of that matters.

No, reduce front droop. Rear always needs more than front.

Ola!

Got myself a TT02 Subaru '99 a few months back, and I think time has now come to build it.

An aluminum main drive shaft and and a set of ball bearings are the only upgrades so far. Bearing in mind I do not want to spend a ridiculous amount money on this car, what other valuable upgrade would you recommend?

To add some spice to it all, what sort of brushless combo would you recommend, together with what pinion and spur?

TYA in advance!

Upgrades:
Oil filled shocks
servo saver
High speed gear set

Motor:
13.5t brushless
64t spur gear (mod 0.6)
29t pinion (mod 0.6)

Thank you for the reply.

Do I understand correctly the manual, a 29T pinion requires a different motor mount?

As far as shocks go, 55mm will do, or otherwise?

No need for a different motor mount to use a 29t pinion. Only items you need to have is Tamiya 54500 TT-02 high speed gear set and 64 t spur gear (Tamiya 51356). 54500 manual gives you an overview which final drive ratios can be achieved.
55mmm shocks are fine, different options are available, Tamiya CVA plastic dampers 54753, or Tamiya 42102 TRF aluminum shocks, or Yeah Racing ones.

JJ,

I have heard that there is a 13.5 TT02 class run in Germany. Do you have any more details on this? Photos? I am wondering if they are the basic TT02 kits with the upgrades you listed, or are people running the higher end TT02 kits?

If you get the high speed gearset then you can run any gears and aren't limited to Tamiya ones. Look at the Yeah Racing motor mount too, it has a slot instead of the set holes so you can set the gearmesh. This means you can run any combination of gears. I would switch to 48p while you're at it, they are just a lot easier to get than the mod .6

13.5T is generally a good match to Tamiya chassis too and the kit ESC shoukd run it fine. No need for the latest and greatest either, a cheap Trackstar motir would be fine, or look at the Surpass range, basically older ones are cheaper, later are better but more expensive, all work well

Thank you all.

Thinking about this combo, in 4000Kv
https://www.hobbywing.com/goods.php?id=579

Will this motor work to its full potential on stock ESC (manual is quite vague on compatibilities)?

TYA!

Thats a sensorless motor so won't work with the Tamiya ESC.

I don't have any sensorless systems so i don't know how bad the cogging would be at low speed. 4000kv is plenty though if you buy the combo with ESC, it should be fast enough

I'm not a racer, so my knowledge is maybe not 100% correct.
Here in Germany we have the Tamiya Euro Cup. According to the 2019/2020 reglement Its stock class is box TT-02 chassis with minimal upgrades, only CVA dampers, ball bearings, front CVD and low friction suspension balls and low friction screws are allowed. They are running Tamiya bodies, Tamiya tires, Tamiya ESC, hand out motors, and even NiMH batteries. Only 70t spur gears and max. 23 t pinion can be used.
Other classes as Top stock ("all-in" TT-01 and 02") or Euro TW (all Tamiya TC chassis but no TRF ones) are also run.

Stock ESC (TBLE-02S or TBLE-04) calls out for either sensored 2pole 540 size brushless motors or brushed motors.
The Hobbywing 4000kV you linked is 4 pole sensorless and will not work with Stock ESC.

If you want to keep Hobbywing choose one of their Justock G2.1 motors, they are a great match for TT-02 and stock ESC. Maybe you have to install a ESC fan, when ESC is getting too hot. Tamiya TFU-01 (45063) can be used for TBLE-02S and others.

Thank you and jgil089 for the reply!

Made my decision and will stick to the HW Combo since I can get a good price for it. Will save the TBLE-02S as a space for my DT03.

I will also get a set of Yeah racing aluminum dampers 55mm. Yaay, can't wait to get started.

13,5T not that I know of. But apart from the Tamiya Euro Cup there‘s a series called RCK Kleinserie running all available TT-01 and TT-02 kits with 17,5 T motors.

Hi Raman,

My CVAs finally showed up, i was in the process of installing them when i noticed (and i dont know how i never noticed before) that the rear hubs have a travel limiter. I realised the rear has zero droop.
Is this limiter normally removed?
