Good to hear! My cars do lots of sitting....the last thing I want is a set of springs that 'go away' over time. I think, in general, the old school companies that are still independent have a lot to offer, for just a few more dollars.
the tool rooms are excellent springs. Its smart running a roller and RPM to not scrimp on valvetrain components.
I backed my rockers off every winter on that car. Dont know if it contributed to the longetivity or not, but it certainly didnt hurt.
Back then i raced a lot more than i do now
