(stick with the faster stuff)

I'm making a spreadsheet like the one above. It looks like the front to rear ratio of spring rate is pretty broad and the springs go from soft to hard and all over the map.

Working on a 425hp 2010 for auto-x mainly. Occasional road course. Even less occasional street comfort.

Z/28 is about 300/500 with very robust DSSV dampers.

I have run 600/600 on coilovers with 5th Gens close to OE weight. On very light builds 300 /500 ish







What about wheels and tires?
Weight reduction?
Cage?

Wheels and tires are 275/35-19 on all four corners. No weight reduction or cage planned.

It works a little bit ok but tends to push like a dozer...

Time to upgrade the rear bar to the outboard style. Bigger springs, higher rates for a full weight 5th Gen which means coil overs.

Alignment specs?
Pain threshold for tire wear vs cornering?
