Default b6.4d clay oval car setup

i have a b6.4d that i run on a high bite, high banked oval track here in Michigan. car runs great but im having a bit of a steering problem. i need more steer in the car. yes i have set end points and adjusted setting in controller already. the car dose not have a ton of push just long sweeping turns for some reason. im running a protek 160t servo.
also i had a guy come up to me at the track after noticing my cars rear shock set up. right now the shocks are in the front of the drive shafts. he was saying to put them behind the shafts for better handling and more steer? is this true. do any of you have the shocks in the back and can tell a difference?

thanks

Can you adjust your toe on the rear? If the rear left is toe in and you toe out the rear right you will get some rear steer effect.

I have moved my shocks to the rear, of the A-arm.

I'm racing a TLR 5.0. I had to rotate my rear shock tower also.

The theory behind the move is, "as I understand it"

Moving the shocks to the rear, moves the weight of the shocks further back on the car.
To give the car a pendulum effect causing it to rotate easier.

Did it help my car ???
I'm not sure because I changed so many other things at the same time.

I do not take credit for this.

Directions: Do one of the following change to your vehicle at a time and drive test.Keep good notes (It's hard to do at the track but try to keep a log it really helps).Also, don't forget to have fun....

Phase 1 (going into the turn) If the vehicle is loose at turn entry then..(needs more traction)
(1) Right front spring is to soft use a harder spring
(2) You need to add more crossweight - by adding a round to the right front spring (add weight to the left rear tire).
(3) Change left front spring to a softer spring.
(4) Lower chassis - keeping it level with the rear.
(5) Reduce front right caster (no less than 2 degree min.)
OR

If the vehicle is pushing into the trun entry then..
(1) Right front spring needs to be softer.
(2) You need to reduce the crossweight - by taking out a round to the right front spring (add weight to the front left tire)
(3) Increasing right rear spring tension by one round
(4) Increase front right caster (6 degrees max.)

Phase 2 (the middle of the turn) If the vehicle is loose in the middle of the turn then...(needs more traction)
(1) Increasing the crossweight by adding a round to the front right and left rear evenly (add weight to the left rear tire)(
2) Use a harder spring to the left rear
(3) The right rear spring needs to be decrease a round (less spring tension)

OR

If the vehicle pushes in the middle of the turn then...(needs more steering)
(1) Decrease crossweight by taking out a round to the front right and left rear evenly
(2) Use a softer spring to the right rear
(3) The right rear spring needs to be increase a round (more spring tension)

Phase 3 (coming out of the turn..) If the vehicle is loose coming out of the turn then..(needs more traction)
(1) Stagger needs to be decreased on the right side
(2) Increase crossweight by adding a round of spring tension to the right front and left rear evenly (add weight to the left rear tire)
(3) Check if right rear spring tension is to much - if it is then take a round out of spring.
(4) Decrease rear springs evenly to the right and left rear.
(5) Use a soft tire in the rear

OR

If the vehicle pushes coming out of the turn then...(needs more steering)
(1) Stagger needs to be increased on the right side if present.
(2) Decrease crossweight by reducing a round of spring tension to the right front and left rear evenly (add weight to the front left tire)
(3) Increase right rear spring tension a round.
(4) Increase rear springs evenly to the right and left rear.

Shouldn't that read Camber instead of Caster?

There's only 1 RC guide I follow for oval and that is the Murffdog tuning guide. It's on the web all over and on petit and I think amain linked to it too. I've known Matt personally for 20 years from when we raced together in SoCal.
