26x11.5x15 ET Street Bias Ply tire.That's impressive. I've ran probably 10 times or so. Best so far is 12.305 @ 114.8mph and a 1.9 something 60. That was on my all season tires. Automatic trans. Bama v2 tune, CAI and offroad X. OP were you on sLicks or street tires?
Solid run!
Skip the welded axle tubes, and get one of these: https://www.cheperformance.com/collections/2011-2014-mustang-parts-1/products/che9l
And a one piece driveshaft if you haven't already.
Do you have experience with the axle brace. I'd like to use it just not sure on how effective it is. How many 6k clutch dumps can I do using this bar before it twists an axle tune you think?
