FDR all depends on your track, A track like Tamiya USA suggested FDR is 3.6.

Front vs mid vs rear motor position
Hiya folks,
I have my car setup in the front motor position and I realized that I do not have a lot of mid corner to out of corner steering. The car is just as fast as other ta07 on the straights.
As I'm using a short pack (I only have shorties cos I use them in buggies), I use the front motor position to provide better balancing of the car.
The car is pretty stock, except I use 1b hanger in the rear rear position, diff as 3k, shock oil is stick 500cps and springs are what came in the ta07r kit.
How do I get more mid to out corner steering?
Thank you!

So which arms is harder? The arms for the TA07 #54740 or the arms for the TRF419 #54691?

running lower oil in the rear helps to plant rear more but car will not rotate as well. I started with 1000 at my track, car had push went to 4000 car had over-steer and was loose went to 3000 car was a little bit better now have 2000 and car corners well rotates good. btw this was with a diff in ft running 500000....if i run a spool i will go up slowly again...most racers with spools run btwn 3000 to 5000 at my track. each track is different. see what your fast guys run and tune to your driving style
Do you clean the diff out and refill or just buy more diffs since they aren't that expensive, and then you can try them back to back?

If I want to add steering/more steering to my setup, what kind of changes can I do?

- damper oil: go harder (400>425>450)
- front toe: not more than 1°
- rear toe: go less - if you have 3°, try 2.5° etc.
- roll center front/rear: go down (less shims on bulkhead side)
- shorter turnbuckles (use another hole on bulkhead if possible / TA07 has no option for that)
- more droop
- less caster angle front: instead of 6° c blocks go for 4° or 2°

There are generally some factors you can change/combine for more steering:
- damper oil: go harder (400>425>450)
- front toe: not more than 1°
- rear toe: go less - if you have 3°, try 2.5° etc.
- roll center front/rear: go down (less shims on bulkhead side)
- shorter turnbuckles (use another hole on bulkhead if possible / TA07 has no option for that)
- more droop
- less caster angle front: instead of 6° c blocks go for 4° or 2°
- damper oil: go harder (400>425>450)

- rear toe: go less - if you have 3°, try 2.5° etc.

- shorter turnbuckles (use another hole on bulkhead if possible / TA07 has no option for that)
- more droop
- less caster angle front: instead of 6° c blocks go for 4° or 2°
Front toe is at 1°
Rear toe is stock setting.
Roll center. I'll experiment with that.
Shorter turnbuckles. Yeah can't do much about that.
More droop. Front or rear?
Caster. Its at 4°. Stock setting.

More Droop: rear
Roll center front: lower - more on power steering
I forgot to mention: You can also try a little harder diff oil rear for more turning. And front a harder swaybar.

Hiya folks,
the kit stock c-hub is 4 degrees. Will I get more steering with the 2 degree c-hubs?
I used the Porsche Carrera gt bodyshell, will using some other shell help? I also have a Alfa Romeo 155 shell.
