I'm 6'. I didn't find an increase. This is a multifaceted situation though- when I first got the seat on ebay, I got a Corbeau slider/bracket on ebay too from someone else. I can say first hand that they are not all the same! I lost so much room between the seat and the steering wheel that I could barely drive the car, or see under my mirror out the windshield. Any Corbeau seat bracket for a Mustang will bolt to any of thier seats, that doesn't mean they are supposed to. They make one with an adjustable height that at the lowest setting is still too high with the CR1, and a non adjustable one with flat sliders which puts the seatbed right back to stock. I had to buy the flat slider one with the new seat, it's been great. OH- Corbeau also makes adaptor plates to bolt their seats to the stock brackets, but they raise the seat. They are only $20, but stay away. The full slider brackets are more like $70, but they are well worth it- far better quality than stock. They are really nice peices. I've found that the memory retention foam of the seat conforms to you over time and buys you a little more room too. My best friend is 6'6, and he drives it without any trouble. Just make sure you get the brackets from a good Corbeau dealer and get the right ones for your seat. If you have a stick car, you may want to look into Maximum Motorsports clutch pedal relocation kit too, it drops the pedal height down to the same as the brake pedal, and gives you way more room for your left leg under the wheel while you're waiting for a shift.
The harnesses are actually designed to bolt to the floor under the back of the seat, I'd have had to drill a hole and get some hardware, or double up one of the sides. They aren't rated for two belts off one point so that was out, and I had doubts about the structural integrity of bolting it to the floorpan too- since when I bought this car the front seat bolts were ripped right out of the floor from doing brakestands. I've also read too many stories about guys getting their spines crushed in accidents because their shoulder harness attatched lower than the shoulders- it should attatch right at shoulder level behind the seat. An alternate schematic in the distructions was attatching at the C-pillar, which I liked. It was a PIA, I had to pull out the backseat and pull the side panels out of the way. The '91's had shoulder belts in back, so I just doubled it up on the stud for the rear belt retractor. There is almost never anyone in my backseat, and it's a much stronger stud than the others. Just elbow grease: that one has a locknut and with my woofers in the way, and not wanting to take the side panels out of the car, there isn't much room to swing a wrench and not enough clearance for a ratchet or air tool. It was worth it though, I like the effect. Glad you noticed it. With the double release harness I can disconnect it to swing the seatback forward to let somebody in the back seat. Of course I took the car right out and started beating on the tires slamming on the brakes at speed, these things hold you in nice. No jerking around like the stock belts. Overall nice parts
. Aparently, Corbeau also offers a "tailoring" to their seats that basically means they can shave a little of the padding to make it about an inch deeper and increase headroom.
