I had my mustang GT for 2 years, modifying it with long tubes, Gt350 manifold, and coilovers. It was my track+street car, and it really fit that role well. 3 months ago I went and sold the s550 and picked up a 2013 E92 M3 comp with a DCT. The difference is night and day. The chassis is far more...

Hey all, After a hard track day last week, I had this code come up. Car is a ‘15 GT, tuned with a GT350 intake manifold and long tube headers, “free flowing exhaust”. 5 months ago I swapped OEM spark plugs. The car runs fine, but on track I experienced a slight jerking when at partial throttle...

So I’m trying to resolve a multiple misfire code. Car is a 2015 GT tuned with a 350 manifold, PMAS 120 mm, kooks long tubes. I’ve swapped plugs to new motorcraft oem, done crank relearns, and the code is still present. What else could cause a misfire? Other than the code, the car runs fine. I...

Currently need to swap out my rotors. There are many drilled+slotted options but I want to avoid drilled for potential cracking issues when I track the car. Some rotors I’ve looked at are stop tech’s, Hawk, and Baer. What are some good pads that limit brake dust? I don’t care about squealing. My...

Like many, I tried researching tuners and pros/cons. Lund stood out to me based on their presence in legitimate racing, history with the platform, and robust knowledge. Before buying any tune at all, I reached out to them and they were very courteous with the questions I was asking. My plan at...

So I’ve kinda settled on the non-adjustable steeda shocks+struts +camber plates+progressive springs. I track my GT maybe 3-4times per year and daily drive it. i’ve seen a few posts noting steeda billet shock mount failures, so I’d like to know if my stock mounts are sufficient for...

Like many people, I’ve dealt with my stock MT82 issues, and scrambled to find the solution. High RPM lockout was annoying since my car is tuned for max power at 8k rpm, and I grew to resent the car because of this flaw. Eventually it gave out on track. -Review——— I opted for the twin disc and...

Earlier this month I had inch and 7/8ths kooks catted LTH installed. Unfortunately I could only source the OEM connection version, so the headers go to 2.25” then back to my 3” catback. There are 3” connection pipes I could buy, but N/A am I really loosing any flow or power? The car is pretty...

This tread is detailing the current status of my track car build. This is a 2015 manual S550 GT Premium, non performance pack. I just finished my 3rd HPDE. I really wanted a premium for the fit and finish. The car isn’t anything special, I’ve just curated parts through verified sourced. I’ve...

For context, my car is a 2015 GT premium with the manual and I’ve owned it for over a year now. Going into the car I expected to have some issues, and I’m still fairly happy with it. To preface this, none of the failures are associated with the engine or transmission. It’s been a mixed...

After tracking my car, I noticed the day after that my clutch pedal started loosing pressure, and I had a warning light about my brake fluid. I found the leak, anyone know what it could be and how to fix it? I was guessing it could be the slave cylinder.

So, I’ve been contemplating swapping out my 2015 GT for one of these cars. My GT has been a fun project to modify, but at this point I’m feeling ready to take the next step into a new platform. It would be a daily driver, and occasional track car. However my next job will be over 50% remote so...

I’ve owned my premium GT for 11 months and I’ll be selling it this winter or next spring. I’ve put on a catback, gt350 intake manifold, and tuned it. Platform is decent and I like the manual, but ford build quality is dragging down the experience. For example the clutch pedal broke at 83,000...

I have a 2015 mustang GT premium with the corsa extreme catback, and I am deciding to pair headers with my GT350 manifold but I’d like to avoid making it stupid loud. Can tame mufflers such as the borla s-type and magnaflow street series bolt onto the corsa x-pipe? While corsa does offer the...

What are the specs on each driveshaft? The v6 driveshaft will shatter over 120 and I thought an easy solution would be to swap in an OEM GT driveshaft that is made for a manual with 3.55 gears. The manual is still the MT-82 so that seems simple enough. The only part I’m not sure of is if the v6...

Besides flow master, are there any other X-pipes due to come out? Are there any universal systems that work with any axle back? I want to get an X pipe to go with a roush axle back.

So I'm looking into power adders, and stumbled upon 2 options: Procharger and vortech. Procharger had the complete kit for 5300, but Vortech has a "DIY" style, where you'd need to buy seperate parts. This however has the advantage of more flexibility in the build. The entry level vortech...

From headers to mufflers, what is the best I can do for performance? I've been looking at a borla cat back then adding long tube headers, but I'm not super sure what the best set up would be.
