At least one and probably as many as you want unless the addition of a number across the back and the shrouding around them would be called excessive and really be about aerodynamics and not stopping the car.

Post by: 1212FBGS on December 09, 2007, 03:37:08 PM: if ya have more than one chute, make sure that the release levers are seperated apart enough so ya dont accedently toss the wrong chute out.....from past experience of course...

Post by: SPARKY on December 09, 2007, 03:57:35 PM: I "now" have my chutes where I can swap tubes --so that at El M I can have the LOW speed as primary the one that has a strg. wheel release!!!!
