Bracket racing???? come on --half the time they are on a throttle stop

I only ran around 200 seat pressure on 800 + lift that saw 9500= several times
I would like to know who made those springs and a part number.
In or USMTS engine that see's 8,200 lap after lap we run Isky Tool Room Gold Strip springs.
Part number 9935.Seat pressure is 245 lbs. and open pressure is 590 lbs.
We run a Jessel system and we have had no broken rockers,pulled studs,extruded keepers/retainers,bent pushrods,busted lifters etc.
In one race on a 1/2 mile track we have five hot laps,ten laps in the main,twenty laps in the feature.
In two nights of racing we will put on more time than an averge bracket racer does in half a season of bracket racing.
At around twenty nights we are putting in new springs.
