Will Hot Bodies be making a spring set for a reasonable cost that Ty will start using? $22/pair of springs is one of the reasons I sent my ZX-5 FS2 SP down the road. I see that the spring pairs for the D4 are $7-$9, much more reasonable.
edit: partially answered my own question from the Hot Bodies UK website -
#113059 - 1/10 BUGGY FRONT SPRING 52.3 G/MM (GREEN)
#113060 - 1/10 BUGGY FRONT SPRING 54.4 G/MM (WHITE)
#113061 - 1/10 BUGGY FRONT SPRING 56.7 G/MM (BLUE)
#113062 - 1/10 BUGGY FRONT SPRING 59.1 G/MM (YELLOW)
#113063 - 1/10 BUGGY FRONT SPRING 61.8 G/MM (GOLD) (Standard)
#113064 - 1/10 BUGGY FRONT SPRING 64.8 G/MM (RED)
#113065 - 1/10 BUGGY REAR SPRING 32.9 G/MM (GREEN)
#113066 - 1/10 BUGGY REAR SPRING 34.0 G/MM (WHITE)
#113067 - 1/10 BUGGY REAR SPRING 35.2 G/MM (BLUE)
#113068 - 1/10 BUGGY REAR SPRING 36.4 G/MM (YELLOW) (Standard)
#113069 - 1/10 BUGGY REAR SPRING 37.8 G/MM (GOLD)
#113070 - 1/10 BUGGY REAR SPRING 39.2 G/MM (RED)
edit 2: Ty was running Kyosho XGear orange/yellow for ROAR nats, IFMAR worlds, and the Cactus Classic. I can't find an actual rating for Kyosho Super Hard/Orange fronts, but Kyosho Hard/Yellow fronts are 75g/mm which is way heavier than the heaviest front HB spring. Kyosho Hard/Yellow rears are 47g/mm, which also heavier than all the HB springs...
For the Reedy race he ran Kyosho yellow/white, which are 75g/mm and 43.6g/mm respectively, which again, isn't covered with the spread of HB springs. Am I missing something with the HB spring ratings?
