So how is everyone pleased with their Z performance wise?

If you make it out to VA I'm assuming you'll be in the DC area? If so, let me know. We meet every other Saturday for coffee and lunch in out here and would be glad to have you.

Here's an onboard of a 12.91 run to give you an idea of the wheel hop.

Did I notice correctly, was it hopping on the shifts!? Ford has always been shy of putting enough tire on those cars. Maybe you can order the Boss rims when they come out, or use whatever tire they are using or something? 255's on that car is just stupid and I don't know why Ford insists on this kind of stuff. My WS6 wouldn't even sqeak a tire on shifts. It would lay waste to mustangs with similar power/weight simply because on the 1-2 shift they lost a car-length that they never came back from. You need good tires for the street, too!

The PZeros do really well on the street, they just don't hook up on track. The hop is pretty bad and costing me a lot of time. I'd probably run 12.60s without it.

The problem is with the soft factory lower and upper control arm bushings. I replaced the lowers but still haven't done the upper yet. I'll be adding an adjustable UCA and some LCA relocation brackets (for a more aggressive LCA angle to increase traction) and should be golden.

I'm also picking up a pair of rear wheels for some sticky drag tires.

Ah yeah. When I did upper/lowers on my 5.0, it made a world of difference. I would have thought that on the new 5.0's they had gotten it right by now, though. Does Ford Racing make a set, who's are you going with?

*When I worked for Ford, we thrashed a 2005 GT 5-speed. It would blow the tires off hitting 2nd gear. IIRC, those were PZero's on there as well, albeit something stupid like 235's, lol. Still, 100whp more needs more than just 20mm more tire.

If you bought what you wanted, who cares how much it cost? I'm not paying for it, and noone else on this board is either--you got what you want. Period.

Those numbers presented in that TCTO spreadsheet are grossly inaccurate. Just sayin.

Were you granny shifting? If you power shift, I'm pretty sure you'll get rubber, at least on the 1-2 and 2-3 shifts....

Shifting pretty aggressively. Not a full-on powershift, but it wasn't leisurely, either. The car just had a well designed suspension (for straight-line) and wide tires. After the tires were worn out, it would catch rubber a bit. Not much, though. Every mustang I raced from a dig would run into problems with me on the 1-2 shift, if not well before. I'm glad I sold it before the new 5.0's came out, although since I was able to stay neck/neck with 2010 SS's, I am curious how it would have compared.
