Not really - if you add Tamiya 54752 you should be ok to go for your steering concern.
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.

I'm with them. Save your money and just enjoy the TT-02 as a backyard Rally car. I wouldn't put any money into it. Pick up an Xpress, a Sakura or better, if your budget allows, and hit the track with that.

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;

PROPOSED Rules for TTGT (Spec class)

CHASSIS: stock TT01 / TT01E or base TT02 / TT02SE ( B/D/T/S/R/RR variants NOT permitted)
ESC: "Box stock" Tamyia ESC as delivered in the OEM box
TIRES: Gravity Racing USGT tires on styled spoked rims
SERVO: Open (servo saver may be added)
BODY: Scale Tamyia Sports car bodies only, no TC, Prototype or Stock Sedan style bodies
WINGS: Molded plastic and only what came in the kit - no non-OEM wings may be added
MOTOR: Tamyia brushed Silver can 540 Torque Tuned motor ( for the initial run this season for the class whatever motor that came in the kit may be run )
BATTERY: Lipo 2 cell, 8000 mah Max

Only Allowed Modifications

• Hex screws may be used in place of the OEM Tamyia screws
• Nylon bushings maybe replaced with ball bearings
• battery connectors may be swapped for Deans or other type connection
• Round Lipo batteries are preferred However - Chassis ribs may be removed to allow a standard rectangular Lipo batteries to be used ( will allow racers to use batteries they may already have keeping costs down)

The spirit of RCGT lives on! I’m happy to see this!

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.

The only changes I would add is functional Hop ups that would allow durability, like the TCS Spec Novice

Speed Tuned Gear Set
Aluminum motor mount
Oil-filled dampers
Alu centre prop shaft

...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.

That's great! Some us can remember when the Slash first came out and all the fun we had in the Slash stock class, When everyone had to go faster, handle better, etc., it disappeared in our area. I hope you have great success and others will copy it.

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.

Just ordered a bearing kit and will call it a day on this one. If anything I will use it to teach my boys.

It's human nature to want to improve and give yourself some kind of advantage. We would still be chasing our dinner with a stick or rock if it wasn't for that.
The track needs to set strict and clear rules. Looking into how past attempts at this have failed and hopefully not making the same mistakes.
Definitely make everyone use the same chassis. Same motor and ESC to keep price down and hopefully attract more people. It be nice if there was a brushless motor that was consistent and sealed so people couldn't monkey around inside of it.
I'm not sure what they can do about everyone buying the same body. Production cars only would get my vote.

I race TT-02 and some things you just have to modify on this car. You will find yourself DNFing about every race if you don't, and that will discourage a lot of people.
I never had any problems with the center shaft. In fact that's still one of the very few original parts on my car. You will be popping front dog bones very easily after a few crashes. A heavy duty wide bumper and O-rings inside the cups will help keep them in. Otherwise new control arms will be needed.
I would leave friction shock in. They aren't that good but keeps things simple for people starting out. The track can do another TT-02 class permitting a few upgrades for people who want to adjust the cars.
A better stearing rack mount is also a must. The 2 screws that go into the chassis will bend and strip out. You need to send a screw through the chassis and nut it on the bottom.
None of these mods will make you go faster. It will just help you finish the entire race and not 2 minutes into a 7 or 8 min one.

Agree.. RCGT is what brought me into racing.. and on the one hand USGT kept the class going but then it’s turned into TC light class

We run a similar class.

The thought process behind what hop-ups are allowed, is durability and driveability.

So we only allow bearings, alloy motor mount, CVA shocks, rear hubs, and front universals.

Tyres are the club's own control tyre.
