captahole Posted December 26, 2016 Share Posted December 26, 2016 I need to add 90 LBS of weight to the car. All I can find in the CCRs is 15.20 Ballast All ballast shall be solid metal such as steel, lead, or depleted uranium, and consist of a minimum of five (5) pounds per piece. Each piece shall be bolted in place with through-bolts, fender washers, and a locking-nut / system (e.g. jam-nuts, Nylock, etc.). All ballast shall be secured sufficiently and all bolts shall be of Grade five (5). Nylock nuts or metal crimping lock nuts should not be reused. Is there any other rules I need to comply with beside 15.20 for Time Trial? Please provide a source so I can look it up to. Thank you.

Clavette Posted December 26, 2016 Share Posted December 26, 2016 In for an answer. Based on the same stuff you read, I just installed this. Four x 28 lb lead bricks. Grade 8 bolts with washers and nylock nuts. Quote Link to comment Share on other sites More sharing options...
National Staff Greg G. Posted December 27, 2016 National Staff Share Posted December 27, 2016 5) Up to two hundred and fifty (250) lbs. of added ballast is permitted. All ballast must be of solid material (no fluids or shot pellets), safely secured in any location on the vehicle approved by NASA safety technical inspectors, and comply with Section 15.20 of the NASA CCR. Page 6 of ST Rules. Page 26 of the PT rules should say the same thing, but we missed it in the '17 revision, so we will fix it. TT will be the same.
