Coilover spring rates?

i have a 95 GT with
MM cc plates
Steeda offset a arm bushings
MM race valved front struts
i just bought the MM bilestien race valved rear shocks, i had tokico 5ways
MM lower adjustable lca
Steeda Heavy duty uppers
17x9 cobra r's with nitto 555's 275/40/17 on all four

Going to order a mm panhard bar and coilovers little confused on spring rate.
Eventually going to buy a torque arm and tubular k too.

i am thinking 425 on front and 300-325 rear? Or should i go higher

Building the car for open track, I have eibach pro kit springs in it now (not even close to enough spring rate, the car was wanting to dig into the ground. Made things very interesting in the curves

Thanks for your time,
Jay

Take it for what it's worth cause I'm still learning.
I had 425s in the front of my cp autocross car, it rolled in the turns pretty bad.
I went to 600s, body roll is half what it was(compared pictures) Turn in is much crisper, over all handling feels much more responsive. and balenced.

I have the MM Race-valved Bilsteins. My car is a dual purpose car, daily driver/autocross weighing in around 3300 lbs. I am running 400# 10" coil-overs in the front and I am very happy with it. Ride is very firm and very controlled. I am not experiencing bad body roll at all like Micha experienced. 425# doesnt sound bad though. I may be swapping to 425's when I get a lighter front swaybar. As for the rear coil-overs I really dont know as I am using H&R Race springs in the rear.

If your body doesn't roll, you're not using your suspension.

I would take a look at how much street driving you're going to do. That's going to be the real driver. At any rate, take MM's advice.

I really don't drive it much on the street anymore it just is not fun unless pushing it. SO i only really drive it once or twice a month. Mainly track days to unleash it. So if 600+ lbs will make it faster I am ok with that.

Thanks
Jay
