No, I probably won’t need to. Right now I still could use more neg. camber since the car is rolling as much as it is. But with all that neg. camber and the inside front tire unweighting I’m putting a lot of heat into the very inside of the tires as it gets drug across the pavement. Once I get the car to level out some I should even out heat and contact patch as-is.
You’d be surprised… the Doug Rippie Motorsport coil overs use a 450/600 front/rear and they claim that is effectively ~30% stiffer than the Z06 setup (my stock spring rates are 525/714 but that is a transverse mounted leaf spring, so the actual wheel rates are way different). DRM claims that’s only 50# shy of what they run on their race cars. But those are road course optimized setups… AutoX is a lot more violent and in general likes more spring rate. I’m thinking closer to 550/700 front/rear but I still have a lot of research to do… then there’s the whole issue of making sure I can get a shock valved to match.
