It is best to have at least 31 spline axles for the record. But here is my story. Well back about 12 or 13 years ago when I got my first 5.0, I didn't have alot of money. I bought a set used Goodyear Eagle slicks 8X26 on a set of Centerlines for $200 from a buddy. I launched the car bouncing off a soft touch (MSD) rev limiter at 6000-6200RPM. The car would spin having a small slick but would cut 1.75 60ft. times. I had friends with motor mods and 10" tread cutting these times or slower. This was with very few bolt ons and stock motor (factory heads, intake and cam). The spin from leaving at such high RPM I think saved the axles my theory. Also the smaller tires don't bite as hard. Never broke an axle. Today my Stang does have aftermarket axles. It is a chance to take and may break an axle. But I gave you a tip if you can't afford the parts and can afford the slicks. May The Force be with You!! LOL
