Is running bias ply (Goodyear Frontrunners) and rear radials (BFG) NHRA legal? Is i t legal for Radial tire class? Is it Safe ?? Also does runnning oxygen sensors with open headers work? I can put collector extensions on (any length) Thank You !!! -Tim

 

going saturday,what should I do ?

 

yes the tire combo is legal.

as far as the )2's you can run them with open headers,dunno if extensions would help or not.

 

I'm not sure how well running open headers and an o2 snesor would work. You can try it, but it might give you some wierd readings if it's too close to the end of the collector. If it does give wierd readings/make the car run crappy I would recommend just getting some o2 sims.
