I’m building up my TT02 as a rally spec car for use on a fairly bumpy buggy track, I notice tamiya sell the Super Mini CVAs and the Mini CVAs. Does anybody know if the Minis will fit? I’d like to get the bigger shocks on if possible.

Or, if they won’t, is there a taller shock tower available, tamiya or third party?

fdr of 4 on a torque tuned will kill it in one or two batteries. I killed 3 of them in one race day and that was at 4.2. The car went like a rocket but got way too hot and demagnetized the motor. This is also on road with a properly shimmed and smooth drivetrain. Off road will probably be worse. I’ve found the sweet spot with the torque tuned for speed and longevity is with the 64t spur and 28t pinion both in stock gear pitch. Puts you at 5.9 fdr.

Outdoors, loose diffs, it's a preference thing but I always ran ceramic grease in mine.

TT02 Rally Suspension
 

What is more important is shock travel. The suspension cannot articulate more than the Super Mini CVAs, and if you needed it to have more down travel, you can always put on the longer shock eyelet ends.

Also, just today I finally decided to remove the little plastic bump on the lower a-arm that stops the suspensions downward travel. Removing it increased it the perfect amount! I originally thought about cutting the lower bump off the upright, but I'm glad I went this route instead.

HI,
I just built a stock TT-02RR. I got the newest Protoform C8 Corvette body for it. The wheels are too narrow for the body, but it works okay.
Is there a way to make the track wider? I was trying to find off-set wheels but came up with nothing.

Does the TT-02SR have a wider stance?

Has anyone noticed how hard it is getting to find RC car stuff?

SR is wider because it uses a different(more racing oriented Suspension). If my memeory is correct, tt02sr uses 5mm hexes whereas tt02 uses 8mm to achieve the same track width.

And yes, this pandemic makes alot of things harder to get.

Is your Corvette body 190mm or 200mm width? (you'll want a 190mm width body ideally, but if its 200mm you can still work w/ it).
You can widen the track width of your car using wider wheel hexes. Your kit comes w/ some in various sized widths (I think), otherwise you can order wider ones. Stock kit is usually 5mm width, you can get wider wheel hexes which will offset your tires.

Also, are you using the kit wheels and tires? they may be a bit too narrow looking for the body you chose. Most kit wheels are 26mm (I am guessing that is what you have)? Corvette's have wider tires in the rear, ...not sure what your using your car for (bashing or racing), but you can check out or think about putting some of these on your 'vettte (they are wider than the stock wheels):

Note: you'll have to get a set for the rear which are 31mm and a set for the front which are 26mm

There are probably a lot more options for wheels/tires as well in wider sizes.
hope this helps

You could try these.

also Tamiya (and other companies) make wider wheel hexes that you can use, just measure the ones you have and go from there, Just make sure you can still tighten down the wheel nut.

The kit came with two wider hexes but the axles are too short and the nuts don't go on.
Thx for the tips!

Tamiya make a wider axle for the standard tt-02 (TAM51529) you would have to buy 2 (only one long axle per pkg) not sure if those axles will fit on the RR though.

The wheels and tyres that come with the TT02RR are 24mm wide inside of tamiya's usual 26mm and im pretty sure are zero off set compared to 3mm off set on all other TT01/TT02

The Ferrari wheels came and although they are wider they don't appear to be offset outwards much.
I also bought tires for TQ Racing only to find they don't fit the rims. They are for the racing trucks (semi's). Don't know what to do with them.
Looks like I wasted $50 here.

What 1/10 scale TC's actual are 190mm wide? I got a TT-02SR and I'm not waisting my time on it if it will look like crap.

The problem isn't likely only the chassis, it's partially due to the Protoform body actually being 193mm wide. I've included the specs from their website below.

Length: 17.68" (449mm)
Width: 7.6" (193mm)
Wheelbase: 10.1" (257mm)

Like previously mentioned, finding the necessary wheel hex width, spacers, or wheel offset (or any combination) is the only way to typically get it perfect. I've personally had great success with 3Racing hexes, along with their spacers to get it perfect.

Wheel hexes:

Wheel spacers:

I'm not familiar with the TT02RR axles, so if getting longer ones isn't an option, deeper offset wheels might be your only choice.

I finally purchased some proper oil shocks and the high speed gear set.

Had a little blast today and the Yeah Racing shocks with the super soft springs were excellent. It’s eradicated all bounce that the pogo suspension gave.

The high speed gear set made a minor difference.
I do want a faster motor still, the torque tuned just doesn’t have enough power.

Also, I’m struggling to keep the car in a straight line after making turns.
As you turn the wheel and let go, the car still wants to go in that direction, until you turn the wheel again.
Are there any upgrades I can purchase to get rid of that and improve the steering, or at least reduce the effect?

Thanks :)

Webarno,
Regarding your steering issue, I would first check to see if there is bind in the steering assembly. Second, I would check the servo saver. They can get sloppy at times. The Xray heavy duty servo saver is the industry standard (IMO) and worth the $20. Third, I would ask about the steering servo you're using. Some don't center very well. Fourth, could it be due to binding in the drive train?
