You get what you pay for. A lot of that money you pay for a real BRIDE seat, is the name. Sure the quality of worksmanship is better on a BRIDE seat, and it meets safety code for track usage, but that's a lot of where your money is going. R&D.
When you talk about ejections, and whatnot, the MOST important thing to look for, is a seat bracket made by a reputable company, and to retain your stock seat belt, or a harness made by a name brand company.
Seats are seats, and that's the bottom line. Some are more comfortable than others. Some are made of higher grade materials. But they're just seats.
Hell, I own a KIA OPTIMA! Made by Korean auto manufacturers. My seats in that car are crap, even though they're leather covered. They aren't comfortable, and half the time I wonder if they're going to fall apart more-so than they already have. But they don't restrain you. The seat belt that has to meat DOT regulations is what restrains you in the event of an accident.
So I guess what everyone is saying is that I shouldn't have bought a knock off car? Sure the quality isn't there, and it's falling apart, but it's a car. It get's the wife from point a to point b, and meets US DoT spec.
The only downside to buying no-name seats, is that if you compete and race on a track, and they don't meet regulation, you cannot run your car. That's IT.
When your car is going through it's safety inspection every year, are they looking at your seats? Hell no.
Bottom line: If you track this car, and those seats do not meet regulation, you're not racing. If you don't track the car, then you have no worries.
