A slight dip at the center will reduce/ slow weight shift to the rear under braking and tepe will have the opposite effect.

Yep. My chassis is set flat with ride heights very similar to yours. But the sagging makes the middle of the car barely clear 4.0mm limit.

You will have to buy more pinion gears. When we race at Timezone we run something like 2.5 FDR
