I have a set of Eibach dampers and the spring rate eibach sells to go with these shocks are 310F/275R (P/P)

My concern is if I put some some coilover sleeves that has a spring rate of front 450 Ib/ft -Rear 350 Ib/ft would it affect how the Eibach dampers performs?

I dont want a bouncy ride or rather have it stiff then bouncey.

Im not use familiar with spring rate vs dampers rebound.

Thanks

 

I know there's already alot of resources out there but my real question is, should the front have a higher spring rate or the rear and which end should have the lower spring rate.

My rear springs are chopped with some cheap looking coilovers sleeves up front and it drives pretty nice, I just want to swap them out with something with similar spring rate as what I have now so I can still keep the ride how it is or close.

Looking for coilover sleeves not spring, spring not low enough.
