We also ordered Planted’s hardware, since there’s nothing worse than being mid-install and having to scrounge around the shop for nuts and bolts or make a hardware store run.
As you’ll see in the video at the end of this post, there’s a million ways to bolt the Momo side mounts to the Planted brackets, so be prepared to try a variety of orientations on the side mounts until you find the right setup for your car and seat combo. Eventually we got it all sorted out, including swapping over the OE seat belt buckles, so the Super Cup seats were ready to be bolted into the Mustang.
Keep in mind, the OE seats have a bunch of sensors on them, so you’ll either want to swap the entire seat wiring harness over onto your aftermarket seats or be prepared to have some lights on the dash for the SRS system. We swapped over the harness for the seat belt sensors, but after trying to trick the computer into thinking the airbag sensor was plugged in and failing at that, we gave up and decided to live with the idiot light on the dash for now. Watch the video at the end of this post for more details on that.
After an initial test fit of the Momo Super Cups we felt the seat was too upright, so we raised the front of the seat one position on the side mounts and this got us into what felt like a comfortable driving position. Neither of us have used a Momo seat before, but we couldn’t be happier with the way the Super Cup fits in the Mustang — there’s plenty of clearance to the doors and center tunnel and we have a bit more headroom than we did with the OE seats, too — nor could we be happier with their comfort or style. These seats are definitely a great option for anyone looking for an affordable FIA approved racing bucket that’s comfortable enough to use in a road car.
I should also mention that the Mullet did shed a few pounds as a result of the seat swap. The factory seats weigh 44-lbs each, which is actually pretty light for an OE seat, and although the Momo Super Cup only weighs 19-lbs, by the time you bolt up the side mounts, sliders, and Planted seat bracket, they tipped the scale at 31-lbs each. So in the end, the Mustang dropped 26-lbs, which is about how much weight I need to lose to get my dad-bod under control.
Pete and I are both huge fans of Momo’s Prototipo steering wheel. It’s classic style is very hard to beat, which probably explains why Pete wants to put one in his 930 Turbo and I want to put one in my Celica. Available with either black or silver spokes, the Prototipo has a 350mm diameter and is wrapped in high quality leather with white stitching, and since it’s a street wheel it comes equipped with a horn button.
Of course you’ll need a hub to adapt the wheel to your car’s chassis, and this hub bolted up to the Mustang’s steering column without issue.
However, the hub is a bit on the short side for the S197 when used in combination with this relatively flat Prototipo wheel, so it’s sitting too close to the wiper and turn signal stalks and dash for our taste. We’ll fix this by either adding a quick release hub or a hub spacer to get the wheel closer to the driver and farther from the dash, or we’ll swap this wheel into the Celica or Porsche and install a deep dish wheel in the Mustang (perhaps one with a bit larger diameter too, since the 350mm Prototipo looks a bit small compared to the gigantic OE wheel and oversized gauge faces in the S197).
That’s a wrap on this round of interior upgrades for the Turn14 Mullet Mustang, but in the next update we’ll be installing some high tech gauges and we’ll also have some DOT harnesses going in soon that’ll make us that much more secure when attacking time at the track.
