11.92 @ 116.7 with Airaid Intake JDM Engineering Custom Tune & Magnaflow Cat-Back

Nice, can you post some pictures of the car? Are the wheels 19x9.5 on all 4?

Yes all 4. The rear has a slightly taller sidewall but it has 285s all around as well. Turning is beastly with that setup.

I think 285/40/19 rear and 285/35/19 front is the perfect street setup, in both looks and performance.

Mustangs definitely look better with a beefier tire in the rear (height/profile wise) compared with the front.

Additionally the extra tire height out back helps straight line grip, while the lower profile in the front helps turn-in sharpness.

285/35's on all 4 is good too, but I think the car looks more RWD muscle/sports-proper with more beef out back then up front.

I previously ran 285/40/18's on all 4 on my 2012, and yeah the grip of 285's up front is great, and almost needed with all the weight on the front of these cars. Had no tramlining issues either. I ran Conti DW's.

We brought our 2015 GT A6 down to the track the other day while testing out one of our N/A Cobra Jet cars and got some pretty good results!

We ran the car in full street trim with 93 octane in the tank and our big and heavy street wheels with MPSS tires.

The car ran a best of 11.94 @ 116.7 mph and was consistently in the high 11s all day long.

Not to shabby for a daily driver with only an Airaid intake, Cat-back and tune installed.

If anyone is interested in a tune or not happy with their current tune we can hook you up with our custom tunes. We use SCT software only at this time.

Impressive! What did it dyno at?

Initially it made right around 400whp. We have made changes to it as we road and track tested it but haven't put it back on the rollers yet to see where we are at now.

We are going to be working on some more cam timing changes in combination with the intake runner controls to see if we can get these car off the line a little quicker (make more torque). A lot of the real tuning is done on the road these days since it is sometimes difficult to replicate driving scenarios on a dyno.

I will keep you all posted!
