If you're in the market for a harness that won't break the bank but still gives you that solid feel, let me introduce you to the Profi 2x2 from Schroth Racing. This isn’t just another seat belt; it’s a serious upgrade from the old-school 3-inch shoulder straps that always felt like they were choking me. The Profi 2x2 is all about modern design and practicality, making it a perfect fit for anyone who takes their racing seriously.
So what’s the deal? Well, you can grab this harness in either 5 or 6 point configurations, which is great for those of us who like to customize our setups. The entire belt is made from 2-inch webbing, which is not only lighter but also works like a charm with HANS devices. Trust me, if you’re running a HANS, you’ll appreciate how this harness wraps around you without the bulk.
Now, let’s talk about versatility. The lap and sub belts come with options for bolt or snap-in end fittings, so you can choose what works best for your ride. And the shoulder straps? They’re designed to wrap around your roll bar, making installation a breeze. No more fussing with complicated setups.
What really sets this harness apart is Schroth's competition-style cam lock. It’s smooth, it’s reliable, and it locks you in securely—perfect for everything from Lemons racing to circle track events. Just a heads up, though: this harness is SFI 16.1 rated, which is great for most racing applications, but it’s not FIA homologated—so keep that in mind if you’re racing internationally.
Fitment: Customized Application—this harness can adapt to fit your needs.
Notes:
In short, the SR 91152PU B-5 Schroth SFI 16.1 Profi 2x2 Seat Belt is a solid choice if you’re looking for safety, comfort, and a bit of style on a budget. It’s built for real drivers who know what they want.
