Is it possible to use 64p gears with the Tamiya alloy motor mount? If so, what gearing combo would be appropriate for a Sport Tuned motor for general parking lot running/racings?

Yes

I'm about to start my build but have a question that I need answered. I plan on racing with this car on outdoor asphalt. What chassis would be better suited for that: the normal abs plastic tub or the hard plastic tub? The racing surface will basically be swept and blown off with a leaf blower. Which chassis tub will give me the best performance and why?? Thanks

Does anyone have the part number for the wheels that come with the TT02R version? I've looked everywhere with no luck. I found the tires but no luck locating the wheels. Thanks

Tamiya 19335728, see manual page 22, bottom half, under the prop shaft

thanks.

What type of servo is better suited for the TT02? A low profile servo or a standard size servo and why?? Thanks for the advice

Both are perfectly adequate.
The advantage of the low profile servo is that it will allow you more room and freedom to use whatever esc you choose and mount it low, directly on the chassis, along with the receiver.

Finding some Tamiya parts can be a challenge. Sometimes the parts are a 5 digit number and are easy to find/purchase. Other times they are a 7 digit number and can be found/purchased directly from Tamiya. Often you can find the parts listed for a model at the very end of the instruction manual that came with your car. Sometimes these parts may be listed with Japanese words which can make it more challenging for speakers of other languages.

When I'm having difficulty finding a Tamiya part for one of my cars, I will find the particular model on the TamiyaUsa.com website. When viewing that model you can select the option for spare parts or option parts and usually can find most everything available for the car. Although it can be hit or miss trying to find/buy the individual lettered metal parts bags.

Another good resource for finding parts for Tamiya cars is the tamiyabase.com website. I just used this website to look up the Tamiya TT02 R kit. From there I was able to determine that the black plastic wheel appears to be Tamiya Part# 9335728 or 19335728. I then went back to TamiyaUSA and typed that number into the search box on that website. Those particular plastic wheels(rims) appear to be available directly from TamiyaUSA. Here is a link...

You can also trying searching through the Tamiya spare part section of their website, but I find that it can be time consuming for me. Maybe there is an easier way to find the 7 digit spares that only come with a few kits. I would be interested to hear if someone has any easier way to find those parts.

Either way, hope this information helps.

thank you for the very helpful information.

If you go with a low profile motor you can fit a ridiculous motor in there. Other wise it at least helps with getting the esc where you want it and/or not having all your electronics nearly touching each other.

Quick question: can I mount the front body posts on the front bumper stay. It looks like there is a spot for body posts on the bumper stay.
​​​​ There appears to be two different mounting locations on the wrx sti body up front. Is this allowed on the tamiya TCS series races? I've read the rules and to me them seem vague. First it says the car must be built per the instruction manual. Then the next sentence states the basic design can't be altered. So I'm alittle confused on if the location of the front body posts would be allowed. Thanks

I always use the bumper stay to mount my Subaru bodies. I don’t like having the body clips right at the hood scoop. You’ll need the body posts from a TA05/TB04 bumper sprue.

You can also use the rear bumper stay to mount your rear body posts. But that works mostly for bodies with a low rear, like sedans. The body posts won’t be long enough to use them for a hatchback body. Unless you get the Tamiya body post extensions

thanks. I know it can be done. My question is it legal to do in the tamiya TCS racing series?

Using the bumper mount body posts does not "alter the basic structure and design". Its perfectly legal.
