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.

We just started up a new class at the club I race at - a tamiya spec class. You guys have any recommendations, or am I fine with just picking a TT02 off the hobby store shelf?

Depends to the class rules and what’s allowed. Are the following TCS ProSpec? Box stock?

I stopped trying to put logic to what Tamiya does ages ago 😂

Has to be out of the box, and can just run the Reedy 21.5 silvercan equivalent.

A box stock spec motor class will benefit smooth drivers who don't make mistakes.

One thing to consider though is the body. A lower body will offer a little performance advantage or over a taller body. Also a body that includes a racing rear wing may offer a little more rear stability since the base TT-02 kits don't have adjustable rear toe-in or camber.

Tamiya 58639-a comes with a Mercedes AMG GT body and is a bit lower than a Tamiya 58699-a that only comes with a small rear spoiler.

The other thing to consider is what speed control is included with the kit (if any). Some of the kits include a Tamiya ESC that can run brushless and brushed motors. Some of the newer Tamiya TT-02 kits include a HobbyWing 1060 brushed only speed control.

2 weeks ago for TCS, my son ran his Spec Novice with kit torque tune in ProSpec with us for qualifiers, since the other novice were no show for first day.

Anyhow, we all ran 64/29 gearing and my sons spec novice set fastest lap. 🤣 he had more top end than our brushless

So stick with the kit torque tuned silver can. It has more toque and better top end than the reedy 21.5. Plus the Reedy is sold out.

Before you buy anything find out exactly what the rules are. Each club is going to have some variations to what is allowed and what's not. I ran the TT02 spec class this past season at my local track. Our indoor carpet track is fairly small so we all had to run a Holmes Hobbies 27T crawler motor, 25T pinion with the 70T spur, a set of Gravity Tires. The upgrades that were allowed were ball bearings, the aluminum drive shaft, CVA plastic shocks w/ all 4 of the same stock springs, aluminum motor mount, Tamiya servo saver and metal dogbones and possibly the cva's but I'm not sure. We had to keep the front diff fairly free and couldn't pack it, and we could run whatever normal car or truck body we wanted but no touring car bodies and we couldn't modify the chassis anyway (like dremeling holes and stuff like that. I had a bought a TT02R since I already had a body and it came out cheaper with the upgrades it has, but due to the rules I couldn't use the the aluminum rear 3 degree hubs or the highspeed gear set. It sucks getting stuff setup and then having to go back and replace parts because they aren't allowed and then retune again.

Heh! That was the one we talked about right? Wasn't able to at the moment, money is tight. Had a feeling it would be gone by now.

So you allowed non Tamiya bodies, so long as they were non TC?
