Why not go back a ball diff in front?
A spool in front on a shaft drive car increase stress on diff, pin/spur gears, specially on high grip track.
I know this set up will have slight less in corner speed. But easy for the gears.
Having a TB03R, 3 months/ 6 times indoor races, I only have to rebuild the F/R diffs once. (LRP QC3, tamiya silver can).

For the loose rear end in your case, try increase droop 3-4mm or more before wheel lift off ground. My club not yet racing brushless, hence i dont know power different btw a 17.5 and a silver can.
hope this help
cheers

Now, I'm running on indoor ozite with quite a traction groove laid into it. The car is just fishtailing all over the place, and I can't get a handle on it.
.
here is my setup :

Front:
ball diff
40 wt oil
Blue springs
1C/1C
Suspension mounts as low, 4deg C hub
arms 2mm towards the back
Tamiya medium anti roll bar
Upper link outside mount - 0mm
Upper link inside mount - 0mm in hole2
1.5 camber
0 toe
4.5-5mm height and 3mm droop

Rear:
Ball diff
35wt oil
Red springs
Shock bottom - short outside hole
Shock top - 3rd to farthest outside hole on tower
1XA/1C with 0 degree hubs
arms 2mm towards the back
Tamiya soft anti roll bar
Upper link outside mount - 0mm and out side hole
Upper link inside mount - 0mm in 2nd hole
1.5 degrees camber
5.5-6mm ride height and 4-5mm droop
Im using MM24-32 tyres out door slippy track, depends on temp. I m not the fastest but i've got consistance lap times with this setting.

Now, I'm running on indoor ozite with quite a traction groove laid into it. The car is just fishtailing all over the place, and I can't get a handle on it.

My setup is as follows:

Front:
Solid diff
30wt oil
Blue springs
1mm spacer on shock pivot mount
1C/1C
Suspension mounts as low as can go
arms 3.5mm towards the back
Upper link outside mount - 0mm
Upper link inside mount - 2mm in hole 3
1.5 camber
1 degree toe-out

Rear:
Ball diff
30wt oil
Red springs
Shock bottom - farthest outside hole
Shock top - 2nd to farthest outside hole on tower
1XA/1B with 1 degree hubs
arms 3.5mm towards the back
Suspension mounts as low as they can go
Upper link outside mount - 1mm and farthest outboard
Upper link inside mount - 1mm in hole 4
2.0 degrees camber

I'm running A tires with medium inserts (trying to keep it TCS legal). The car is balanced and tweak-corrected.

If anyone can give me some advice, I would greatly appreciate it. I'm really getting frustrated with this car, and I'm ready to toss it and go back to the TA-05.
Hey there Ransom fellow, are you in rochester hills michigan or are you somewhere else. Also which carpet track do you run at. I run at MSI raceway and I also have a tb03 that I sometimes run, mainly in vintage or rcgt classes. It would be great if you could come to msi I could then show you my set up for carpet which is pretty good.

I used to run at Larry's, but haven't since they turned their track into stadium. They just moved, and we're hoping they put in an onroad track in addition to the stadium track (they have the room now).

I have been going to MSI lately, which is were I've been working on my setup. As an example, a decent lap in 17.5 rubber on that track is around 11 seconds. I'm ok at 14 seconds, but as I push the car to go faster, and start to get down in the low 13s/ high 12s, the speed is just too much for the car.

If you can give me any help, I would REALLY appreciate it. When do you usually go out there?

@ mrod check your droop screws in the arms. kit setting will do just that on high traction. try screwing them down ft and rear until the car feels better.try 5 ft 4 rear to start. or 4/3 always run slightly more up ft. and this car handles almost identical to my ta05v2 with the same set up. as all the parts are the same

always start with the trusted tamiya set up of blue/yellow springs..and yellow/red sway bars.

try that...and see how it goes.

Default TB03 on rubber gym floor surface

I am thinking of picking up a TB03 (stock version out of the box) for some indoor racing this winter.

I will be running it on a rubberized gym floor in a highschool. Any tips of setup? The traction should be really good (rubber on rubber). The organizer has run his GT car with HPI X-pattern tires and said it had really good bite.

My first guess is to drop the ride height (super smooth, no bumps), and stiffen everything up to help it rotate.

Suggestions.
