Coilover spring rates
I know a number of us have converted over to coilovers. I have mine and really like it. Looking over at the DRM site, I see the offer coilovers but there’s no specific indicator for ZR-1. We know the motor and overall car is heavier than the
base C4. Anyone know what spring rates DRM specifies, and secondly, if u have coilovers, what spring rates are u running F/R? Inquiring minds want to know. 😁🙃

Re: Coilover spring rates
I have DRM coilovers but have no idea where my receipt is to confirm the spring rates. I took what they suggested....
If they are stamped on the spring I can look....425/300 looks familiar. Are you running DRM coilovers?

Re: Coilover spring rates
For u guys contemplating coilovers, let me recommend u do the Vette2Vette
No Flex. A little more inexpensive, less hassle to install, but definitely angreat bang for the buck. I would still do coilovers, but the NF definitely changes how ur car will ride.
