Track toys that are daily driven present themselves with a unique challenge. Where do you draw the line between racecar and every day streetability? Do you sacrifice comfort for a few tenths? There is really no wrong way to approach this as each individual’s build is custom tailored to the owner. I’ve been following Michael Heintz’s beautiful Boss 302 for a while now and have had the pleasure of witnessing it slowly transform into the car that it is today. From first rate suspension and a passion to do things right, it’s only fitting that we feature a track prepped Ford Mustang Boss 302 for November’s Garage Files – Domestic Edition.

What type of car do you have (mod list later on in the questionnaire)?

My car is a 2013 Mustang Boss 302 #0166

A lot of people give their cars nicknames/actual names. Do you have one for the Mustang?

It’s funny because I actually have never named any of my cars.  My friends call my car Mach Yellow

Is this car your daily driver? If not what is your everyday car?

This car is my Daily Driver.  I wouldn’t have it any other way.  I wouldn’t build it to have it sit in my garage.

Have you always wanted to build a newer Mustang? If not what other cars have you built/modified?

My first car that got me into tracking was my 2008 Evolution X with the SSS package.  The car had full bolt ons and was fun to drive.  When Ford announced they were bringing back the 5.0 engine I knew I wanted one.  I preordered a 2011 GT with the Brembo brake package.  I was one of the first in California with the new 5 liter and a lot of companies used it for research and development.  The car was driven by Adam Carolla on The Car Show on national TV.  When the Boss 302 was announced I knew I wanted one, because it was a purpose built track car.  My plan was to leave it stock but as you can see, it didn’t work.

How do you feel about the KW Clubsports compared the old setup that you had? Would you recommend these for a fellow racer even though they are a high dollar item?

The KW Clubsports are amazing.  I was blown away when I got on track.  Once Conrad Grunwald helped me get the shocks adjusted with proper rebound the car handled amazing.  My car was put up against a 2014 Camaro Z28 and was only 1.2 seconds slower around the road course.  To me that’s a win considering my car was a major underdog as far as Engine and Brakes.

Has there been an alignment setting that seems to be a “happy-place” for your applications, or do you realign the car based on the application (street/track/autocross). Would you be willing to share these settings with the community for those that may be wanting to set the car up once for all applications?

I run -3 degrees of camber and 0 toe.  Being a solid axle there is no adjustment to the rear.

The Boss Mustangs have a broad power band out of the high revving V8 and of course there are some people that chase a horsepower goal. Since you now have tracked the car pretty extensively and are intimately familiar with it, do you feel that the car lacks power in any situation? Would you want more? If so, how much more would you feel is adequate to retain the balance of the chassis?

The stability provided by the rear wing allows Michael to confidently push the envelope at every track session, while staying in control.

The stability provided by the front splitter and rear wing allows Michael to confidently push the envelope at every track session, while staying in control while having over 470hp on tap.

My car makes 473rwhp and 370rwtrq  it is perfect for the car.  The power band is useable all over.  The redline is set to 8200 but the car makes max power at 7900.

Is there a track that seems to favor the car more than others in current configuration? What do your times look like for the Socal faves (Autoclub Speedway/Fontana, Buttonwillow, Willow Springs, etc).

Big Willow 1:35.xxx

What’s your favorite track to drive? What is the time goal that you want to set for yourself and achieve in 2016?

I love Big Willow because turn 8 and 9 give me that rush of adrenaline, but I love Streets of Willow for the technical layout of the track.

Are there any sponsors you would like to acknowledge for their assistance in getting your car to the way that it is?

I would like to thank every single one of my sponsors because without them my car would not be where it is at today:

  • Toyo Tires
  • KW Suspension
  • Mcleod Racing
  • Ford Racing
  • Bassani Xhaust
  • MGW Shifters
  • Maximum Motorsports
  • Trueforged Wheels
  • Built2apex / Kognition Racing
  • Voss Performance

As most of raced cars undergo continuous changes, what are the next plans for the car?

I would like to put a one-piece drive shaft on the car and possibly upgrade the front brakes next.
