Default F-type R awd suspension

Hey guys

​​​​So I tracked my ftype r awd last weekend. The car did really well and it was a blast. Very impressed by it considering it is a gt car. Now my problem. The stock suspension is good but there is too much body roll in the corners. My BMW m4 is much more at home at the track with the adaptive suspension.
Thinking of changing the suspension on the jag to make it roll less in the corners and improve the handling.

Any suggestions? Will the progressive rate lowering springs from velocity ap help?
​​​​​
Grtz

From what I've seen on their website. They do not have a kit for the R AWD version. I could be mistaken

For the track, I would strongly recommend the H&R full drop. That will eliminate virtually the entire roll. If you still need more anti-roll, a larger rear swaybar would be the way to go.

My opinion which probably won't be shared by owners who mod their suspension by changing ride height, spring rate, damping or sway bars is good luck making a change that will improve handling in one area without great potential for deterioration in other aspects of ride / handling particularly with a car that's going to be used both on the road and the track.

Lowering ride height with shorter springs will lower the roll centre and likely reduce cornering roll, it will also reduce total suspension travel which isn't desirable, the lowering kits try to compensate for this by having variable rate springs. The so called variable rate springs are usually two rate rather than truly variable as with conical springs or ideally air suspension. Changing spring rate without appropriate changes to compression and rebound damping rates usually also comes with unintended and undesirable side effects.
Suspension design isn't a subject I would consider myself an expert in, but I know enough about the subject to be aware it's vastly more complicated than many would believe.

It's your car and your choice
