I've been changing the mounting of the rear hubs and front steering blocks.
I did switch them arround as when you should do to make a TT-02 Rally version.
By doing this i need to mount some smaller dampers, so i did use some TRF mini dampers to become the correct ride height.
I mounted some VTEC 30R tires to see how the car performs with this setup.
Going to test this setup tomorrow on a high grip carpet track, i will keep you guys informed how it went.

The car was on rails even without tire sauce, just cleaned the tires and drive.
Even though i was only using a silvercan motor but the car looked very fast and stable.
The most important thing i noticed was that when you mount the rear hubs and steering blocks like a rally version they become stronger.
Normally when i hit the boarding with the TT-02 (cause of to tide steering) the steering block would have been broken, but even after a few times of to tide steering the car (steering blocks) were still fine.
I can only recommend this to everybody who is running a TT-02 and is able to mount some smaller dampers (like TRF mini dampers).
@Qatmix,
You really should try the setup explained above, you will love it
If you need more explaining just PM me
cause i'm unable to send a PM to you.

That's correct, but we have been using the car at the belgian TCS and there it isn't allowed to use TRF dampers in the junior or top stock series.
And because we are going to compete with another touring car championship (where it's allowed to use TRF dampers) i've been testing them with my new setup.

Trf dampers as opposed to which? I have used the setup for rally on carpet but this was an unfair comparison as my car had been used for off road a lot. I ended breaking the rear left hub on the straight from the boarding if that's what you call it so I don't think its necessarily stronger due to a different setup.
I still have hit the boarders 1-2 during practice and not broken any knuckles/hubs. I'm also using a 9t motor so not too slow either on the straight

When i said the rear hub&steering blocks are stronger by using them in rally configuration then it was mostly ment for the steering blocks.
I'm using the alu 2.5° rear hubs, these are very solid.
When you would mount the rear hubs and steering blocks as it's ment to be for on road racing then the steering blocks are very fragile and do break very easily.
My little girl broke a lot of these steering blocks with very minor crashes that a car should be able to handle without any problem.
This was the biggest problem for every TT-02 competing at the belgian TCS.
I have never broke 1 rear hub, even when i'm using the standard versions under racing conditions.

They are indeed more expensive but IMO worth every extra $$$.
My car runs great with those super mini dampers but with those TRF mini dampers the car was so much more stable and planted and it does improve your laptimes.
I will keep trying to improve the cars handling with several other setups and tires.
My fastest laptime with just a silvercan motor was 11.053seconds, while on this same track Markus Mobers (1/12th stock european champion) have laptimes arround 7seconds with his modified 1/12th car. I think this isn't a bad time for a silvercan equipped basic car.

No i don't have some laptimes with the super mini's.
I'm counting on what my eyes see and how i feel the car is driving arround the track.
For example i never use a roll out when i'm driving a F1 with foam tires or a 1/12th scale car, but i Always been able to get the gear ratio to be correct.
I'm mostly make dicisions on my feeling and so far they never let me down, but i'm getting older and you'll never know when i could be wrong.

I've got a TT02 in the mail. SUPER STOKED!
Does anyone know if the HPI vintage treaded D compound tires are a direct fit 26/31 for the kit(Carrera RSR) rims?
Also, how is the stock gearing for your local VTA/Scale Spec? I'll be running a tight indoor carpet track.
Thanks,
-Tommy

I have the tt02r that came with a 19t pinion and it topped out half way on the straight but also I had rubber o rings at the hubs so it may have caused the drive to be less free
If you can avoid buying the tamiya AV pinions as wear shows even after one session of play
For me I think 20-23t pinion may be right. I used a 25t and it was slightly too fast on the straight and too sluggish for me in corners
Hope that helps

Wow, that helps a ton. Thank you.
For VTA, does anyone know if I will need the offset wheels for the carrera body? I will be getting the 26/31 rim combo, just unsure of offset.
Thanks in advance, painting starts tomorrow.
