The Raikiri is the best imo. The BRZ GT300, Ferrari 458, GTR, STI are all very decent or a 04 NSX lid if you can get ahold of one. Use a set of 26mm wheels as well, all the way around and see how it goes.

Well, normally I would agree, but in the case of this particular RSR body, I will disagree. I raced it for 2 years in VTA using the short wheelbase. This body was more planted, had more steering than any VTA body.

So If set up correctly, it will surprise you.

Thanks I missed that. Ok well there is your issue right there, you can’t race a car with oil filled shocks using the pogo sticks lol.

If your track allows it, pick up some yeah racing shocks. if it has to be Tamiya pick up the plastic CVA or if you can spend a little more the TRF shocks. Either way, you need oil filled shocks

My suggestions were mainly based on box stock no options. I hear you though! The tt02’s are so capable with a good pair of hands.

Those Pogo stix gotta go though lol.

Next would be slicks that come with the Porsche kit. I bet you they are using left over stock from TA01 days in the 90s. The rubber on them is junk.

The released the Super Grip radials on 30mm, pair those with the front 26 mm and it will change the car dramatically.

Hi all,

Thanks for all the info!

I agree, 80% is tyres. i just hadn't realised they'd be using different tyre compounds/rubber in the TT line up

I actually like the way it looks bouncing around, look more realistic to me :)
They do allow it, ive ordered some Tamiya CVAs.

i have been running this car for years now and normally finish top 3. I just thought everyone had the same traction issue, as they always complain of lack of grip.I
I've just learnt to drive it like a proper 911, just annoying when i get it wrong and spin out.

These are the ones i have -Tamiya 50547 (SP547) Wide Racing Slick Tires w/inner Sponge (1 Pair).
I've ordered some Tamiya CVAs, do you mean reduce the rear droop to stop front weight transfer?
I'll try a set of the Super grips if this doesn't work. Edit - Seems the Super Grips are out of stock everywhere!

For those interested in how much wear you can get out of these, i ran the kit tyres for 3 years - Outdoor asphalt (32s lap), we have a large, low grip surface
By this stage it was basically on the carcass, and noticeably affected the top speed/rollout

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.

Raman 08-11-2021 09:29 AM

@Monsta

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!

JJ100179 08-22-2021 07:20 AM

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?

JJ100179 08-25-2021 12:14 PM

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
