Lower the rear ride height as much as you can, understanding it's a bumpy track

raise the pod side of the shock, a least 1mm, and don't be afraid to add more

what are you using in the side damper?
I'm using damper lube from D-Drive in the side shock (X style) and the front kingpins. I'm not sure of the weights but the are labled Super Soft, Soft, Med, & Hard. It currently setup with the SS.

The pod side of the shock has the stock spacer on. I believe it's 1.5 mm.

Hmm, is it possible the car is rolled over too much in the corner? Maybe it's not squaring up, or it's just too twisted up when you get on the gas. Stiffening up the side to side action may be counter intuitive, but may help the car from getting too far out of shape. I know that the "hi traction" t bar on the older car was actually detrimental on some low traction tracks because the t bar could twist more. The green t bar without the cutout worked better on those tracks since the car kept the weight centered uip more.

It's almost like the car is getting locked in a turn and just keeps going once the wheels are straight. Yet once I'm out of the corner I can be more aggressive with the throttle and the car will track correctly

My current setup is:

Rear ride height - 5 mm
Pod droop - 3mm
side springs - pink
TC Rear Shock - 25wt. and gold (mini) spring
Rear tires - Tamiya TCS (rebadged Pits)
Diff slips for 1-2ft from stand still

Front ride height - 5.5 mm
Gold springs
2 deg camber
front axels in the offset position
Front tires - Tamiya TCS (rebadged Pits)

Using a Shorty pack
Battery all the way forward, electronics behind battery

Thanks for the help!
We have been searching for a working setup quite much and found it in a direction we did not first expect. We had similar problems as you.

Track is a bit bumpy, medium traction, small medium size and we run on Pardus tires and LRP traction compund on full tire back and front normally.

Try the following adjustmements
Rear:
Lower rear end (we even use 1mm shims under the motor mounts to get it really low, I think we run about 4mm, be sure not to tweak the pod when you assemle it with the washers)
1mm droop in rear (you will need to put a shim inside the damper, I think we use 3 or 4mm shim)
Harder side springs, we use silver or gold depending on traction, we do have them pre-loaded.
We use TRF shock with 500CST oil and Yellow (medium) spring, however will test 900 oil and soft spring because the car is jumping and bouncing too much.
We use the friction roll damper with 30k oil in.
Carbon axle (weight too high up with the metal one)

Front
3,5mm ride heigh, this is the lowest before the king pin hit the wheel, unless you use a widening kit in the front then the king pin will clear the wheel and you can run 3mm ride height.
0.5-1mm droop.
Black or Gold springs depending on traction
1,5 deg camber
2 deg caster (exotec front) but std works well too.
15g weight in front of the servo
We use a long battery because our final is 30 min.
Do not use anything on the king pins but will try smth next time to get rid of some bouncing.

Edit:
We also use 1mm shim under the upper suspension arm both in front and back (front is the "camber" arm and back is the "caster" arm) hope you understand what I mean..

Is there a servo horn somewhere that will eliminate the servo saver completely?

If you eliminate the servo saver completely you run the risk of damaging your servo

Don't care
I don't run servo savers in any of my cars, 4wd SC, 2wd MOD SC, touring car mod, etc. Never had any servo issues so a SLOW car like a 21.5 F1 should be fine, and I will just buy a new servo or gears IF it blows

If you look at the pictures of the box there is nothing mentioned on the parts list of an alu servo mount
It does have an alu servo horn for the hi-torque servo saver

I trust tamiya website. It may not be one of the more important hop up parts included so it wasn't listed on the box but I think it is included.
