My race series just adopted the Radical Cup 710Kg min weight requirement. Does anyone have experience with running at this weight? Ballpark how much ballast would I need as a 160lb driver and an SR3 without air jacks?
I wouldn't think you would need any. As a 270 lb driver with 8 gallons of fuel I'm nearly 1700 lbs.
Wow, I'm surprised. I heard others in our club complained that they were at a disadvantage to the smaller guys, but in this case nothing would change. Do you have air jacks? That would be another 25lbs or so.
My SR3 XX w/o air jacks weighs 1400 lb. This had about 7 gallons of fuel. in it.
