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.

Thanks for the inputs, @davidf and @gwt561324.  Looks like I should be ok for our sprint races without any ballast, especially since we start each race day with a full tank.
