Just completed a TT02 rally build today. I havent been into RC cars in a long time. Most of my last 10-12 years of RC has been helis and planes.
I cannot believe how much slop is in the front suspension and the lack of bearings, turn buckles, etc. I have ordered a bearing kit. I was looking at the hop-ups to bring this chassis into a respectable track car. Looks like you have to put about $200 into the base kit. Is that right?
If I am going to do that I should have just bought a high end racer $450-600 to begin with. Am I wrong here? Like I said no RC cars in the last 15 or so years. I do remember I had HPI RS something that was tight out of the box years ago.

The cost to make the TT-02 a tack capable car is high and it will never compete well. There are so many other 'entry level' sedans out there that are far superior that it makes no sense to spend $$ on upgrading the TT cars.

This will have to become a basher for the front culdusack when the kids are playing out front. The only tracks in my area within an hour are clay off road for buggies and trucks. Seems like the 15+ years I have been absent from the car game all the local tracks have vanished.

I assume your kit has adjustable shocks so you can mess with spring rates and fluids so no extra money here.
Want to firm up the tub for tighter steering response, they make an aftermarket carbon brace and that's $20 but not needed for rally.
If you want to lower the FDR you get the high speed gear set for $10. All in you're at maybe $50 and done.
If you really want to go faster, you need to find a non-tamiya motor mount and large pinion, but this is probably overkill for rally too.
Otherwise, you 'can' get the aluminum prop shaft and joint, it won't make you faster, but doesn't wobble like the stock one at higher speeds. Same with changing any of the non-adjustable parts for their adjustable options. These things usually are stock on the R and RR (and to a lesser extent D).
The $200 number you saw was probably for appearances stuff (aluminum and carbon all the things!) but don't really impact performance at this level.
As others have mentioned, the TT02 is good for spec racing, or racing at lower speeds. It is objectively an excellent racer, just not in every class under the sun.
If you want to do stuff in 17.5 TC, or USGT, it's not the chassis for you because at that level being able to tweak every little thing is important and the 02 doesn't have that ability without substantially changing lots of parts. Not saying it can't be done, but as others said, it ends up costing more than a basic kit from another brand.

Built box stock there is substantial slop, but it can be shimmed out if you are patient for relatively little cost. Bearings are a must and it amazes me that Tamiya still sells these kits with the white plastic bushings when a full bearing kit costs as little as $7 anymore. At least they could include the bronze bushings.
The cost to make the TT-02 a tack capable car is high and it will never compete well. There are so many other 'entry level' sedans out there that are far superior that it makes no sense to spend $$ on upgrading the TT cars.

TT-02 is a good car for a hobby store to use to get new people on the track. The low price and lack of adjustability makes it easy to get into racing. Newcomers are not overwhelmed by the endless adjustments most other cars have. This gives rookies a much better chance to win with little practice. It's one of a few classes of racing won on the track and not the workbench.
This is a low cost entry level car, made more for bashing, so your going to get slop. A lot of people that buy RC cars use them 5 or 6 times and that's it. Plastic bushings fine for that. Get the bearings if your one of the few that races it in a TT-02 class or want more use out of it. This car will need some money if you want to race it against X-ray, Shumacher, or Associated cars, and you will be at a disadvantage. Those cars are made for racing.

I think the TT02 with bearings is a good car. One of the problems we have in r/c racing is the thought that we all need one of the top and expensive brands to have fun racing. I think that if we want to draw more people to r/c racing is that we have a less expensive class to race in. The Euro Truck is an example of a class rules that should be applied to other classes. The EuroTruck Class is good, but the bodies are too expensive. In some places the run a "TT" class with then same basic rules as the Euro Truck with the exception of tires and bodies of course.

Exactly. The key word is "Fun" and the TT-02 kit can provide lots of inexpensive fun for anyone looking to try on road racing. My club, along with a few others in the area, are trying to start a TTGT class using the base TT-01 and TT-02 chassis. No SS or R models, just the base versions. We've set rules as follows;

the day USGT opened the doors to PF bodies was a Pandora’s box. Now PF, Bitty, Monetech, McCallister, Exotek are all making “lookalike” bodies.

...and racers are spending hundreds, if not thousands of dollars, on top-line sedan chassis just to compete in what was to have been a more sportsman type of class.

Allowing these upgrades defeats the purpose and intent of the box stock class and I would discourage anything like this. Leave the cars as stock as possible so that everyone has the same opportunity to succeed. It's tough getting younger kids to stop playing Nintendo Switch as it is, no need to open Pandora's Box by allowing upgrades. The Tamiya Truck class is fun and no upgrades allowed other than bearings.
