Perf driving = 425
Racing =450

Mary has been running the 350 rate since last fall.
James has 425 on OLC and it's doing very well. With the Ride Tech shocks set at mid-range, the car rides great on the street.

We had some indication of hitting the bump stops on Mary's car when she tried lower shock settings. So we will be trying some stiffer front coils. I think if you have a more streetable ride height, the 350's will work fine, but I'd turn the shocks up for an autocross.
FYI, Morrison runs/ recommends a 450 front coil on their 69 Camaro.
Thanks David. I ran the Ride Tech tool (nice job there, by the way) and came out in the low to mid 300's depending on shock travel. My car's not down in the weeds (my LCA's are essentially level with the ground), so I should be okay at those spring rates.

The 350 lb./in. springs came in today, as well as the nitrogen setup for the rear shocks. I'll get everything installed, drive it and see where I am. It's quite possible that a new set of front shocks are in the cards.

I have tell tales on the rear shocks, which are about 1" to 1.5" from bottoming out.

This car is primarily a long distance tourer that's supposed to be fun on curvy roads; it's not focused on auto-crossing or HPDE.
