NHRA Rule Change!

[12secSS]

This doesn't apply to Keith anymore , but maybe to others like myself (the SS, not the Z28 ). ;D

Adjustment to E.T. requirements
In a move designed to encourage more street vehicles to compete on the quarter-mile, NHRA has revised its requirements for roll bars, SFI Spec clutches, driveshaft loops, driver restraints, and certain protective clothing.

Beginning Jan. 1, 2005, a roll bar and an SFI 16.1 driver-restraint system will be mandatory on any vehicle running 11.49 or quicker and for convertibles running 13.49 or quicker. An SFI 3.2A/1 jacket will be mandatory for all drivers in vehicles running between 10.00 to 11.49 seconds. On any car running 11.49 or quicker, a flywheel and clutch meeting SFI Spec 1.1 or 1.2 and a flywheel shield meeting SFI Spec 6.1, 6.2, 6.3, or 9.1 will be mandatory. A driveshaft loop will be required on all cars running 13.99 or quicker and utilizing slicks, except vehicles equipped with street tires running 11.49 or slower.

That's nothing... check the shit that IHRA is trying to pull...


NHRA T-Top cars = same rules as Hard Top
IHRA T-Top cars = same rules as Convertibles in some instances (or so they're trying to change it)

10.00 to 11.49

Rollcage: Add at the end of the section, A rollcage is mandatory on all convertibles running 10.99 or quicker ¼ or 6.99 or quicker 1/8 mile. T-top vehicles follow convertible guidelines.

11.50 to 13.49 section

Rollbar / Rollcage: A minimum of a 6 point roll bar is mandatory all convertibles and T –Top entries running 11.00 to 13.49 ¼ mile and 8.25 or quicker 1/8 mile. A roll cage is mandatory on any entry that exceeds 135 mph.

Fortuanetly they're revising th rules... but still trying to make it 12.25 or faster for a roll bar... which is BS (I dont' care as I already have one)

Rollbar / Rollcage: A minimum of a 6 point roll bar is mandatory all convertibles running 11.00 to 13.49 ¼ mile and on T-top entries running 12.25 or quicker 1/4 and 8.25 or quicker 1/8 mile. A roll cage is mandatory on any entry that exceeds 135 mph

For a convertible didn't it used to be like 13.99 or faster needed a roll bar anyways?

oh I just noticed that they're saying roll bar and restraint is necessary for any vehicle running 11.49 or faster

That's a RULE BREAK NHRA , as far as I know, is currently 11.99 or faster you need at least a 6 pt roll bar and restraight... and IHRA is currently 11.49-10.00

So looks like NHRA is dropping the times down .5 seconds for some of the rules....
