Finally Got Both My Sparco Seats Installed :-)

My moms Trailblazer SS makes over 400rwhp and it has reclining seats.

The 5-point harness without the roll bar is asking for trouble. That is if you use them.

How did you hook up your harnesses?

If a 4 point harness is installed without the shoulder straps fastened directly to the rear (meaning if they go below your shoulders when secured) it increases risk of breaking your collarbone.

More so where you stay in place in the seat and harness, you can have your head crushed in a roll over without a roll bar. In the same sense with a roll bar your head could bounce off the bar in a collision. It's a no win situation.

They do look good! How much weight did you save?

watch how you mount the belts. they are at an unsafe angle for your neck/back.

Angle is 21 Degrees. Sparco says 20 is good.

It's only "no win" if your choices are "driving around with a rollbar and no helmet" and "driving around in a fixed-back racing seat with a 'make-do' four-point harness."

The factory seatbelt and airbag work rather well in the kinds of accidents commonly seen on public roads. A rollbar and racing seat with four- or five-point harness and helmet work rather well in the kinds of accidents seen on a roadcourse with an ambulance and extraction crew waiting to respond.

The problem with hitting your head on the rollbar comes from trying to use the factory seats with a rollbar. Even with a helmet on, you shouldn't be positioned where your head can hit the bar in a collision. If you mount a racing seat on the floor you can get far enough away from it to be reasonably safe. But that's not a position most people want in a street car.

Nice seats, but never cared for the way racing seats look in a street car. They never match the rear seats, or the rest of the interior, and they look really odd with random unused holes if not used with a proper bar.

Not for me, the stock seats in our cars are actually really nice IMO.
