I find myself plagued by this constant desire and urge to build a Fox body. Having started several projects in the past but never seeing them through to fruition, I decided to right that wrong. My love for the Mustang platform runs deep, and I would be remiss to forget about those models that came before. The Fox Body is one platform that we all have love for, and building a set of 4-lug wheels to showcase what can be done only seemed right.

The car was a simple craigslist find. Bone stock with tons of documentation, surviving paint, and a 4x4 ride height. A little persistence and patience got me the car for $5500. My goal with this car is build it to be a baby GT350R if you will. Following an OEM+ design philosophy I want to modernize the car into something streetable and trackable like the GT350R. Experiencing what a car that is a complete package with a synergistic relationship amongst the components has changed what I want out of a car.

Along with the fully forged Signature Wheels I have plans to give the car a full treatment with components from Griggs Racing, Baer Brakes, Carters Customs, Steeda, MGW, Trackspec and a few others. Hope to bring some write ups, reviews, installation tips, and comparisons against the GT350R along the way.

Here are a few pictures to get the ball rolling

Sounds awesome. It would be cool to have custom ground flat plane crank to put in the fox 302 block. Run a standalone ecu to get the firing order right and rev it to the moon.

Followed by breaking the crank, block and all of the accessories in half. There is a reason that the FPC crank is not listed in the Ford Performance catalog and it is no longer used in any Ford vehicle.

A FPC allows the engine to rev higher with a given induction and exhaust system because both systems have perfectly evenly spaced pulsed air flow events. It makes better use of given peak airflow limits on the input and output side. This is good for a racing class where you are limited by displacement and inlet restrictors for instance, but not limited by rpm. It costs a ton of money to make the engine not vibrate itself to death with a FPC. It has no place in a production car.

Custom ground flat plane crank would cost more than he paid for the car, and you would never put that into a stock block. So now you are looking at a $2k block added to the $6k+ crank. I see that concept cost a cool $30k+ to take advantage of the flat plane crank. The only reason to do it would be because nobody else has done it. A regular cross plane crank can easily go past 9k rpm for a lot less money.

Guys...relax. I wasn't serious. I was just thinking it would be unique, fitting for the theme, and sound cool. And so would a Voodoo swap, both given unlimited budget.

Anyway, back to the thread. Sounds like a cool build. Will be following to see how the suspension comes together.

The fox has some really good qualities about it. One of them being the surviving paint job that it has now. The body itself is very straight with only a few minor scratches and dents. The worst paint area on the car was the aftermarket hood, and it has some peeling clear coat. For some reason the previous owner decided to spray the cowl vent and windshield wipers to match the car. One of the first things I plan to change.

I bought the car at night and then stored it at my brother’s house. By the time I saw it again in the daylight it was filthy. Decided to drop the car off at Imperial Works in Sacramento to see what they can do with it. They did all the outstanding detail work on my GT350R. Told them to get to it whenever and see if it can be brought back to life. Got the call to pick the car up after a few weeks and check it out. I can say that It was definitely a happy experience. The factory paint job cleaned up extremely well for some polishing and paint correction. Ceramic coating will come later and I look forward to those results.

Oh yes :smile2:
Nice starting point
This is by far the best fox I have ever started a project with. A lot to be said for starting off being able to do upgrades as opposed to repairs.

This would be a cool concept. Midway Mustang is putting a voodoo motor into a foxbody now. curious to see how it turns out with the NVH of that motor into an older car without all the dampening.

In order to make the Fox worthy of track use I know there are a plethora of areas to be addressed. In my experience it is better to learn on a slow car with a sorted suspension, than a fast car with a suspension system that is out of whack. This will be handled thanks to Griggs Racing.

While those Griggs components are being built, I am going to work on some aero, aesthetics, and reduction of heat. One of the first parts to get installed will be a Trackspec Motorsports hood vent. As seen with other Mustang models and aerodynamic testing the best location for the vent is directly behind the radiator. This helps to pull hot air up, through, and out of the radiator. At speed it will also help to prevent lift by reducing under hood pressure. I looked over some installation tips from FJD Performance about using tape to locate the spot directly behind the shroud. After some quick measurements with the template from Trackspec it was time to get cutting.







Used a Ryobi angle grinder with a cutting wheel and some prayer to get this done. A file came in handy for those corners where you did not want to run to far. Some work with a rivet gun and the deed was done. The first cut is definitely the hardest, but once you realize you cant go back it gets easier. This hood vent is made for the S550 and based on the GT4 car. The supplied rivets are too short to go through my aftermarket hood so some longer ones had to be sourced. Looks good though.




Working for a wheel company and playing around on track have taught me the importance of lightweight wheels to reduce unspring weight. Having a setup that is strong, stiff, provides adequate caliper clearance, has proper fitment, and leaves you with enough threads for your lug nuts is tough to find. Not to mention the lack of available wheels for the 4-lug platform. To start I will build the new Signature Wheel Reserved SV902 in a 4 lug for the car. Eventually the car will see a 5-lug swap due to my desire to run the Griggs SLA up front, but for those with no need to swap we will have some excellent custom-built options. Here is a peek at what is coming. You will notice the front is not concave due to the amount of protrusion from the front hub/bearing. A concave wheel will not allow the front center cap to fit, which always drive me insane with I see it. These will be a direct bolt on to any 4-lug car, will not require any modification, and the front center cap will fit. Not to mention weighing only 20-22lbs in an 18x9 / 18x10.

Are those special order from Signature or do they make 4-lug wheels that fit the foxbody?

Nevermind - just saw your sig LOL
We can custom build a number of our wheel designs in a 4 lug. Just depends on the look you want and then I can spec out all the specifics from there.
Where’s the damn tech?
Its coming brother. Bit of foundational work needs to happen before I can really get into some of the more technical stuff. Appreciate you following along.
Love the hood louver, wanna help me with mine, I haven’t built up the courage to cut my hood, I’ve had mine for months now and don’t know if I’ll ever get it done.
Would be down to help if you are in California. I got a lot of good info from other track guys about the high/low pressure areas and optimal locations for air flow. If you have any questions please let me know. Until then here is a good article to read.

The Fox is not an inherently aerodynamic vehicle. Inbound to help with some of those issues are components from Carters Customs. The owner Adam Carter is an engineer by trade and does an excellent job making all of these parts himself. Install on these cannot come soon enough. The car will see his front splitter, fender vents, rear diffuser, side skirts (once developed) and a Steeda Aero Spoiler.








On the subject of aerodynamics I also was able to get a set of custom LED intake lights made courtesy of Stuart Gaskins of Premium Fuel Mag. These were created and developed as an idea to get more air flow into the radiator and liven up the front end of the car. They are out of production but some persuasion made it possible to get another set built for my car. They operate a white LED during normal operation and flash orange like a turn signal. Cant wait to get them. Part of my plan to build the car as a complete package is modernization of the systems.

As a fellow Sac area foxbody owner, subscribing!

I can't wait to see pics of the splitter on.
The splitter looks very good. I have not had a chance to get the car out of the garage with the various parts getting installed. Looking forward to showing the completed package soon.

I'm interested to see how the rear diffuser mounts to the gas tank and bumper area. Looks like it will be one mean track weapon!

I hope it is. The diffuser mounts using rivnuts that go into the plastic cover. They are pretty cool and now creates a threaded hole for the nut to go into.
subscribing to this cool build...I really like the LED airflow lights...
Thanks T
