Regarding the ride height measurement, I find it less easy than on standard carbon car because of the shape of the chassis at the rear. At front, it is indeed trunkated by the protruding bumper support.

One thing regarding your description of the technic to adjust droop : are you making reference to the shock collar adjuster ? I thaught droop could only be set by putting shims under the piston in the shock body ? Because on the SRX, there is no possibility to put droop screw in the TRF420 arms.

if you had the standard kit with the original suspension, inserting spacers in the shocks is the recommended way.

The type S/SR/SRX use touring car lower arms, which had holes for the set screws that adjust droop. The Type S/SR has arms with set screws on each side, because they were reversible, eg could be flipped over, giving you more botttom shock options. They worked perfect with the optional part from Tamiya. With the SRX they got lazy and included arms from the 420X which are not reversible and have the hole for droop on one side. They should have simply added a hole.

Using the droop screw is more precise so I’d opt for that with the SRX

TT-02 Spec Cub Racing.

Had overall TQ but got P2 in the Main because the car's steering felt inconsistent (never could get it to track straight) and cause the car to pull all of the sudden on the last 30 seconds.

Driving my SRX.

Usually the wandering steering is the weak servo saver in these kits. If you are allowed I upgraded mine to a Xray ultra stiff servo saver.
Ah I see you are in VA. I was hoping to come down to one of their events with Hobbytown, but 4-5 hour drive for me.

I swapped out the servo saver for a solid Tamiya blue one.

I live in Northern VA so I'm part of the Radio Control Racers of Northern VA club. The Hobbytown series in Richmond also looks awesome.

Stock Dog Bones popping out
 
Other than not clanking boards or side rails does anyone know of a way to help secure the stock dog bones from popping out of the front end of a stock TT02? Tonight practicing I experienced this a couple times, once I think it was from such a hard impact but the others they were slight brushes with the barriers. We run a stock class that does not allow changing to driveshafts / universals. Thanks in advance 😃

Ensure the steering arm stop is installed. It goes on top of the driveshaft just behind the front differential case. That combined with the stop on the front hubs work in tandem to help prevent the bones from ejecting when everything flexes from brushing the boards and other cars.

Box stock.... What comes in the box is usable am I right? Take the rubber tube that is on the motor shaft and cut it to be o rings. Put the "o rings" in the axle cup on the diff side so the axle is pushed into the stub axle side.

Do you use the anti-roll-bar kit from Yeah YR-TATT-034 in the SRX on carpet or asphalt?

RaceDoc 08-15-2025 11:09 AM

Does somebody use the Yeah Ring carbon droop plates on the TT-02 SRX? How would they been mounted?

Yes that's a link to the product. But mounted on a TT02 it minimizes the ground clearance...

And there is a photo showing how it's supposed to be installed. Wasn't that what you wanted?

RaceDoc 08-18-2025 11:20 AM

Yes and no! The photo shows the mounting in the rear which is no problem because the three screws are "free".
In the front there is the bumper holder, and you don't want to mount the droop plate under it because it harms
the ground clearance.
