126 MPH you should be a solid mid-10 once you get it dialed in. Iím a leaf spring, manual trans racer so I donít know the Mustangs (yet; father / son project in progress) but itís imperative the front is able to rise as quickly as possible; if not quicker than possible. No sway bar, loose strut adjustments, front coils that are taller than stock with a thinner wire diameter. Definitely no to any kind of ďhandlingĒ springs! If you get real serious, low resistance control arm bushings; no to prothane or similar ďhandlingĒ bushings!
Rear-end must have negative pinion angle. Donít know angle what works best for stock-type Mustang rear suspension but, I would guess -3 to -4 degrees.
What clutch are you using? Thatís a critical issue that has not even been brought up yet. I assume you have a manual trans as you mentioned 40000 RPM launch and I see no mention of a tranny brake.
