I was going to suggest reaching out to Tamiya fans on Tamiyaclub.com, but it looks like someone has already helped you there.

There is also Tamiyabase.com as well as the Wanted to Buy forum here on RCTECH.NET...

Good luck on your quest.

haha yep, I offered to ask here since hes been looking for 2 years! Will post in the wanted, see what comes up

I’ve made a Stock TT02 editable set-up sheet to download. Following this I also thought I would share my base set-up for asphalt tracks.

In the memo sections for the dampers, what are the 0.4 and 0.2mm shims for?

For a parking lot with less traction, would you run softer springs?

Those shims are used to fine tune the ride height. They ate 3mm internal diameter. Slide them on the piston and then fit the ball cup. This adds a finer amount of tuning to the ride height when using plastic CVA shocks.

If you use the TRF threaded units then you don’t need to do it as they provide fine adjustments anyway.

For low bumpy tracks softer springs are fine, but I would still start with the above. It is a very versatile base set-up.

I would first however add shock rebound to ensure the tyres are always in contact with the more uneven surface. This provides more grip than you could imagine on car parks etc.


Also adding more ride height can give you more lateral grip in the corners, but you will suffer if there are any faster switchbacks etc.

Alright guys, got some PETG filament in so have been printing, tweaking and test fitting for a couple days. The Front Splitter is the 3rd version and the Rear Diffuser is on its 4th version already. I have a side skirt I've designed for the left side that I am tweaking that fits well, and I'll mirror it for the right side then add the additional cutouts. The skirts will attach to the sides of the bathtub chassis. I haven't decided between clips, screws, or double sided tape for mounting yet. First sets will most likely get the double sided tape for testing.

Let me know what you think along with any design suggestions you may have. The side skirts are simple, straight ones at this point.

So you are running zero droop? because you are controlling the ride height with the shock lengte

No. Normally you reduce droop in front, to maybe 1mm over ride height.. eg you push down on front shocks to settle suspension.Then you pull up on body posts and you want upwards movement around 1mm. Rear you do around 2-3 mm.

Finished up the aero kit. After work today I'll try to modify some of it to make it more "generic" to fit more kits. The diffuser will take quite a bit to make "universal" so I'm not sure about that one.

That looks pretty clean. Nice work.

Thanks man! The diffusers and side skirts took a bit of work to get right, But calipers made things easier at least.

I was just wondering if anybody knew what hop up items are included in the TT-02R kit that aren't in the TT-02SR. When I saw the SR kit I noticed it didn't have the aluminum drive shaft and was wondering if there where other items like that, that were missing.

R/RR different kits than S/SR. The R/RR user the traditional TT02 arms which are upper and lower arms. The S/SR use touring car arms that use C hubs and camber links.

The R/RR seem to come with more aluminium hop ups than the S/SR

Thanks for the reply but I was just wondering if their are any other parts that come in the R kit like the aluminum drive shaft that aren't in the SR version? It was just weird that the SR comes with the standard plastic drive shaft. You would think that the SR would have everything the R has plus more.

Here is a good web article that discusses the differences between the on-road versions of TT02 vehicles. This article doesn't talk about the TT02B or TT02T
https://www.thercracer.com/2014/08/t...-and-tips.html

There are also reviews of many different Tamiya vehicles including the different versions of TT02. These articles included some suggested hop-ups and upgrades.

As to the why Tamiya releases different versions of their vehicles like they do, I am not sure. I have read some good explanations online before but can't find one right now. Maybe someone can post an explanation or a link in this thread.
