Tamiya TB-03
#2221
Are you using the standard soft parts or the carbon reinforced? I noticed some mushiness before I did mine with the carbon reinforced. The soft tower will flex. The carbon reinforced doesn't.
If you go to the carbon-fiber shock tower, you will get a little of the mushy feeling from the front. I had to add 5mm of shims between the tower and upper shock mount.
I have since upgraded to the EVO6 bulkheads, which are milled to mount the towers 5mm further out, and the TB-04 carbon towers. This really improved the consistency and feel from the front end of the car. It also allowed the finer shock angle adjustments. Only downside is the new towers are made for the new short dampers (same as EVO6 ). I was able to use standard shocks\HPI Silver springs with the new 418 threaded upper and 1mm-down lower and was able to get down to ~4mm ride height - most tracks are 5mm min so good enough.
The rear is where I noticed a nice little perk. With the tower mounted more to the rear, and the use of a standard width tower, the body post are now the same as my 418. All my bodies are universal again.
This is going to be a fun indoor season.

Make sure you check your car's balance, including F/R bias. Standing the shocks up moved a lot of weight from behind the axle/below bulkhead to front of axle/above bulkhead. I usually only need 10-15g added on the motor side rear to balance. You will likely also need to run thicker oil while stood up vs IFS.

Please help anyone....I have 2 questions.
The tires that came with the car, how durable are them? On asphalt.
I bought this car to play on the street. Im putting my old mamba max pro with a 4600kv. Can anyone recommend a starting out pinion gear. I will check temps to make adjustments after.
Thanks

ready for "I wonder if this works" experiment
TB03 VDS undrift spec
swapped ball diff and spool back<->front
ackerman steering kit.
LRP x20 17.5 stockspec
weight distribution is very Front Left <-> Right Rear heavy
Let's see if this thing works... at all

I ran my TB-03 last Sunday in my club's Sportsman class (21.5 blinky) and managed to qualify 4th for the A-main. There was a Tamiya FF03, a Serpent S411 FF and a Schumacher Mi4CXL on the grid in front of me. In the main I took advantage of mistakes by the leaders to take the lead on lap 2 and held on for the win. Mine is the gold coloured Porsche 911 in the following video. Longest 5 minutes ever.

The TB-03 is a great club racer and works well in our Sportsman class with a 21.5 motor. I just need to work on my driving and hold better lines.

Hey Steve, would you mind posting your setup? I was at the time Zone gran prix this weekend and was able to put my tb03 3rd in the VTA B main. A tenth less per lap would have put me in bump up contention. I needed a little more rotation for the two hairpins and switch back. Thanks-Al
ps I was able to put my S1 7th in the 17.5 B main. Couldn't call my hands down.

TB-03 Setup
I can't find a editable setup sheet that uses the standard front suspension. My car started as a stock plastic version, but I have upgraded along the way. I have the Tamiya alloy spur gear adapter, 3Racing blue motor mount, Tamiya motor adapter, Tamiya front spool, stock ball diff in the rear, option Tamiya main shaft and rear shaft, TRF shocks with the white springs, red springs in rear, yellow in front, 3Racing graphite front & rear shock towers matched to the 3Racing alloy shock tower mounts. I am running a Reedy Mach II 21.5 motor with 75T spur and 50T pinion all 64 pitch. Sorex 28R rubber.
Shocks on front are mounted at the outer mount on rear arms and most inner hole on shock tower. Shocks on the front are also on the outer mount on arms and mid position on shock tower. I used the oil that was in the kit for the shocks and no idea what weight that might be.

Your car was stable but scrubbing way to much in the corners. Run tamiya whites up front and blues in the rear. If your track isn't high grip maybe blue/ blue or blue yellow. Your set up is to soft
