Project 88 GT update

[Mustang_289]

Well guys/gals - update on our project 88GT stang that my son and I have been building. My son just broke into the 13s (13.5) for the first time with the car! It is so cool watching your son run the 1/4 mile.

Still working with him on his RT and 60' times to get improved. Not too shabby with street BFG TA radials and stock suspension.

Here's a list of mods to date:

CenterForce DF clutch
MAC long-tubes and hi-flow catback
underdrive pullies
Pro5.0 shifter
ZEX 75-100 shot
Kenny Brown subframes
aluminium driveshaft
3.73s
Eaton posi
31spline axles

Still stock:
stock top and bottom end
speed density

On order:
adjustable rear control arms with poly bushings

I'm wondering if he could break into high 12s with good suspension work, good tires maybe slicks, and better RT and 60' times. Any comments on whether this is possible with above setup?
