10.99 1/4-mile (6.99 1/8-mile) or quicker:
-5-point roll bar is still okay to 10.00 1/4-mile (6.40 1/8-mile) in hardtop / t-top with un-altered floors, firewall and frame rails (wheel tubs are okay). If the floor and/or firewall has been modified, then a full roll cage is required beginning at a 10.99 e.t. or any vehicle running 135 mph or faster (regardless of e.t.). The roll cage must be constructed of a minimum o.d. mild steel or chrome moly tubing (moly can be a smaller o.d and is lighter but more expensive), see diagram below for specs. Roll cage must be padded anywhere the driver's helmet may contact it while in the driving position, see diagram below for specs.
-Convertibles require full roll cage at 10.99 and quicker.
See diagram below.
-aftermarket axles with positive retention (c-clip eliminators) (good there)
-Transmission shield SFI Spec 4.1 at 10.99 and quicker or 135 mph and quicker (blanket is okay, no expiration date) (great )
-Harmonic Balancer SFI Spec 18.1 (no expiration date) (fine there)
-Protective Clothing (SFI jacket with a 3.2A/1 rating, no expiration date) (need to check mine)
-5 point harness (up to date, they must be replaced or re-certified every 2 years; (even on stock/factory seats ?)
-SFI-approved flywheel and/or clutch (no expiration date) (I'm good there)
-Screw-in valve stems (Really ?)
-No tint allowed on window except factory
What else ????Anyone ???? please
