- droop : 5.4mm (measured with shocks mounted, and adjusted by putting shims between the piston and the shock body onto the shock axle)

- Shock oil : 500cst
- Shock position top : 2nd hole from the top of the damper stay
- Shock position down : Tamiya 54943 in position C (i.e. : the most outward or closer to the wheel side)
- Camber : 1°
- Roll center : 1mm shim under the ball on the inner side / 0,5mm under the ball on the outer side (wheel side)
- Toe : 1°
- Ackerman : 1mm shim
- 1mm each side between wheelhubs and tyres
- Ride height : 5.4mm
- Spool

Rear
- droop : 4.6mm (measured with shocks mounted, and adjusted by putting shims between the piston and the shock body onto the shock axle)
- spring : SMJ 2.9
- Shock oil : 425cst
- Shock position top : 2nd hole from the bottom of the damper stay
- Shock position down : Tamiya 54943 in position C (i.e. : the most outward or closer to the wheel side)
- Camber : 2°
- Roll center : 2,5mm shim under the ball on the inner side / 0,5mm under the ball on the outer side (wheel side)
- Toe : 2.5° (flat, no skid angle)
- Ride height : 5.7mm
- Gear diff filled with 5k cst
Based on the setup above, what change can I bring in order to gain more "free" speed within high speed turns ?
Indeed, my car with the above setup is able to turn into high-speed corner at full speed, but struggles to maintain its speed : I can litteraly see the car slowing down throughout the corner (I'd say starting from end of entry / begining of mid-corner) even if I'm full gaz on the radio still (no slight slow down nor braking input). A fellow racer with a Schumacher Mi8 was able to carry much more speed than me within the same corner whereas he got the same top speed at the end of the straight than myself and he full speed turned in as well.

Thanks for your ideas !
