I have a S/Pro Dragster that will be running 7.60 in the 1/4-mile and about 4.80 in the 1/8-mile and want to make sure that I have the correct rollcage padding.  Do I need the SFI Spec 45.1 rollcage padding?

Answer:

Roll cage padding meeting SFI Spec 45.1 mandatory on any vehicle running 9.99 (*6.39) or quicker. Padding must be used anywhere driver's helmet may come in contact with roll cage.
