Can I have an opinion of suspension experts?

Hi,

I am a novice on suspension design and my knowledge doesn’t go any further than what I have read in different handbooks. I have designed my first front suspension for a two seats sports car, rear engine and weight around 450 kg.
Attached, a copy of the result graphs from the Dynatune sdm program.
I am looking forward for your comments.

Doesn't Dynatune encourage a top down approach to suspension design, ie first build a vehicle level model with your desired targets, and then cascade down to hardware?

Also it is very hard to tell anything from plots of one end of a car only, but your ackermann plot looks plain weird, it is well on the way to zero ackeramn at full lock.

Cheers
