I'm a bit confused about how roll center correction is classified under the NASA TT points system. Does it fall under "16) Alteration of ball joints/dive angles +2"?

And if that is the case, if one has adjustable ball joints already for camber correction, is the addition of roll center adjustment essentially points free?

Thanks for help.

Also, am I correct in thinking that the KW V3's will take a seven point penalty?

2) Non-OEM shocks/struts/dampers with a retail price of greater than $600 ($2400
total) or $750 each if sold only as a coilover with spring included ($3000 total). Also
“Piggyback” external reservoir shocks/coilovers/dampers with a retail price of less than
$1050 per unit ($4200 total)—must still take additional points for the springs below +7

(They cost less than that, so do they then fall into the following?)

3) Non-OEM or modified/re-valved shocks/struts/dampers +3 (all others)(springs not included)
4) Non-OEM or modified coil springs, leaf springs/spacers/brackets, or torsion bars +2

(Five points total for new struts and new springs?)

Which rules are you looking at? Are those older? (I'm looking at http://www.nasaproracing.com/rules/time_trial_rules.pdf )

Which for suspension just says:

2) Non-BTM shocks/struts/dampers with a “Piggy Back” external reservoir (fixed reservoir
without a connecting hose) OR with shaft diameter 40mm or greater—must still take
additional points for the springs below +7

5) Non-BTM or modified coil springs, leaf springs/spacers/brackets, or torsion bars +2

So as I understand it you take +7 for the shock and +2 for the spring for a total of +9. I have still been working to figure out the rules myself, though

But they cost less than $3000 (they're not external reservoir). As far as the date on the rules, maybe has google has steered me wrong. I'll double check.

Price doesn't matter. Those rules are super old. Those are 7 point shocks plus 2 for springs. And they are external reservoir BTW.

As to the ball joints. I believe you only take the 2 points one time. So upper ball joints and roll center adjusters is still 2 total. But I'm not 100% on that.

I'm fairly certain that's the way it works.

KW V3s for the S2k are +9 due to the external "piggyback" reservoirs. Modification of dive angles is +2 for the ball joints.

The $$$ rules are old rules and not current as of a few years ago as others have said.

Thanks everyone for the fast responses!
