Lots of good GT4 pictures here: https://www.mustang6g.com/forums/threads/dean-martins-gt4-mustang.86581/

The FP350S rear lowers look like a production Ford piece, as opposed to the GT4, which has a fabricated, billet aluminum lower. Attached is a picture of the FP350S lower, I do not have a picture of the GT4:

Camber plates will through you into at least Street Touring in SCCA autocross (NASA autcross I am not suer on the rules, but NASA is not as big in autocross as the SCCA is). You can tyically get 1.4 to 1.8 degrees of negative camber on OEM strut mounts and no camber bolts through all of the...

The S197 Mustangs can keep up in a stock class using true street tires (basically over 200 tread wear tires). As soon as the AWD cars like the Evo's and STI's get decent sticky tires (200 and nder tread wear), that's where things seem to change. True street tires seem to even things out rather...

Shock and spring adjustments can help you out with this, but in general, from what I've found, you're going to get this if you are braking hard over rough/uneven surfaces to some extent in general, SRA or not. Actually, LCA's with some type of rod end can help the rear out in this too. Whatever...

I have my 3" cooling ducts routed along the bottom side of the front sway bar, the ducting squished (ovaled) at the touch points and zip tied and I get a little bit of rubbing with 285's on a 10" wheel with +35mm offset and a 5mm spacer. Not a lot of rubbing but enough to wear away a small arera...

That particular intake is a different story, haha. It would be even better if it were sealed from heat and drew air from a similar location to stock (cool air from the high pressure area of the front of the fascia). An open filter element like that, without a proper cooler air source, is fine...

I wouldn't be suprised at all if any of you guys went back to the stock airbox and didn't lose hardly, if any, power at all.

It turns traction control and advance track OFF all the time. It retains ABS, but to a different calibration more suitex for the track.

I also want to add this: In the 2011-2014 cars (whether it's a V6, Boss or GT), turning everything OFF doesn't really, truely turn everything OFF. Th system is still on and dormant in the background with limited ability, but can and will turn on under certain, extenuating circumstances. The only...

This has happened to me once and another guy on the same autocross course. Both cars are 2012 Mustang GT's. The course had two very different surfaces (black top and concrete), tight, sweeing corners and long straights before the corners (a lot of HARD braking).Button held down while stopped...
