Your Slice
Automatically Squaring Your Clubface for a

"That Should Be Impossible…"
Chris McGinley leaned forward, eyes locked on the screen.
On the track, a racing car screamed into a hairpin turn at 200mph.
He braced for the inevitable: a skid, a wobble, a violent spinout.
But it never happened.
The car held its line like it was on rails.
McGinley, a veteran golf club engineer, couldn’t stop thinking:
“Race cars can take corners at 200mph with total stability… so why can’t a golf driver head stay square at impact?”
That’s when it hit him.
Race cars aren’t just built for pure speed.
Instead, they’re engineered to balance speed and control.
Everything about a race car is designed to help the driver maintain control at high speeds.
But golf drivers?
They’re built for one thing: speed.
And they assume the golfer is perfect.
When club engineers design a driver, they design it for a tour player.
Someone with flawless mechanics, elite timing, and the ability to square the face at impact without thinking about it.
They don’t design it for the everyday golfer…
… Aka, the weekend warrior who doesn’t have 20 hours a week to perfect their timing.
That’s why amateur golfers slice.
Modern drivers expect you to deliver the club perfectly—even though your brain physically can’t react fast enough to make those micro-adjustments in time.
And that’s the real problem.
McGinley knew that had to change.
WHY TRADITIONAL DRIVERS FAIL (AND WHY THEY KEEP YOU STUCK IN
SLICING HELL)
For decades, golf companies tried to "fix" the slice problem the wrong way:
By making YOU change YOUR swing to compensate for THEIR flawed club designs.
They added "anti-slice" shafts…
Adjusted loft angles…
And told golfers to close the face manually at impact...
But none of it solved the real issue:
The face of a traditional driver is inherently unstable through impact.
Just like a racing car would be without advanced counter-balancing and aerodynamics.
However…
RACING CAR ENGINEERS ALREADY KNOW THE SECRET TO FIXING
YOUR SLICE…
Engineers have spent BILLIONS perfecting how cars correct themselves through turns at insane speeds.
- Counterbalanced weight systems automatically adjust steering to prevent spinning out
- Aerodynamic stabilizers keep the car locked on the racing line, even under extreme G-forces
- Torque distribution adjustments eliminate instability when hitting tight corners
McGinley realized a golf driver could do the same thing.
If a racing car could correct itself automatically, why couldn’t a driver correct its face at impact - without requiring tour-level
timing and wrist control?
That was the spark that led to the SF1 Driver.
THE SF1: THE FIRST DRIVER THAT SQUARES THE FACE FOR YOU
For two years, McGinley tested, refined, and pushed boundaries—applying racing physics to golf club engineering.
He cracked the code when he combined three key innovations:
- AeroSquare Crown – Inspired by racing car aerodynamics, this crown shape forces the clubface to square itself at impact,
reducing drag and eliminating that frustrating open-face slice.
- Counter-Slice Weighting – Using the same principles as racing car steering stabilizers, McGinley strategically placed
weights in the driver head to automatically correct face rotation at the moment of impact.
- Anti-Slice Face Curvature – While traditional driver faces let the ball spin uncontrollably off-center, SF1’s face curvature is
engineered to guarantee draw-spin even on mis-hits.
