Default KW V3 + Js RCA - Car too low

Hey guys, got a quick questions.

Right now I am running the KW V3 with J's front and rear RCA. The car is around 3" off the ground from the jacking point.

The coilover is already set to the maximum recommended HIGHEST position and the car is still too low.
The helper springs are baiscally totally compressed right now.

Will I have any problem running like that?

I am running RE11 255 all around non-staggered. F 32lb, R 30lb nitrogen

F camber: 3 degree
R camber: 2.8 degree
F toe: 0
R toe: in 1/4"

I have cusco 32mm sway bar upfront and stock AP1 bar in the rear
Also have bump steer kit up front and rear, as well as a AP2 subframe.

KW setting:
Compression F&R: 1-2 sweeps (from full stiff)
Rebound Front: 5 clicks (from full stiff)
Rebound Rear: 7 clicks (from full stiff)

Right now the rear end is very loose. A little more steering input and you can feel the back wanting to come out.

Any suggestions or feedback to my setup is greatly appreciated!

I don't see any mention of a wing and you have 255 all around?

The rear are coming out at pretty low speed, at around 30, 40mph.

The KW settings were made yesterday and it was wet out. Also my tires are semi bald in the rear, so i am sure it has got something to do with that.

Before I made these changes I was running the KW recommended setting out of the box and the car felt a lot more neutral.

A lot of people said they had good results with the KW settings so I gave it a try but now the rear end is very loose, so I was wondering if it had anything about the coilovers height and the helper springs being totally compressed.

If the tires are bald and its wet out, softer spring rates (and damper settings -KW's recommended settings are softer than the settings you stated) will generate more grip.

Try your current settings in the dry.

It does sound like your car is too low. With your car in the air, measure the length of the main spring in mm.

I will measure it tonight.

I agree that my car is too low as well, however with the RCAs, it's already at the maximum recommended height from KW.

Are there any remedy to this?
