BK seat lowering brackets mod

[2000SoCalBoxsterS]

So this weekend I got around to lowering my seats with the BK seat lowering brackets that are supposedly specifically designed for my exact seats. It did not go as smoothly as I had hoped. I needed to lower my seats because my head was still too high to pass the broomstick test for DE events.

I followed the meager instructions and removed the side mount brackets that connect to my sliders and replaced them with the shorter BK brackets. But when I tried to replace my seats the holes in the sliders (which were not changed) were not exactly lining up with the holes in the floor. It seemed that the seat slider frame was about 3/8 to 1/2 inch too wide now? WTF???? Why would this happen? Only the seat height changed not its' width? Of course I took them apart and put them back together several times to make sure everthing was put together tight and correctly,but with little change in fit.

The only thing I can think of is that the BK brackets are more straight up and down whereas the stock brackets angle in slightly from the sides of the seat down towards under the seat. But this is supposed to be a perfect no fuss match according to BK. They are in now, but what a PITA!

Are you putting these lowering brackets onto the sliders? my BK lowering brackets floor mount using a BK floor mount bracket that removes the sliders...

OR you could have the wrong brackets... if you post up a picture I can see if they match mine... but I will say my driver side was a &$#@* to fit width wise with the sliders but I didn't use OEM brackets... I used brackets much like the BK lowering ones... I just had to force it

Hey Easyc, thanks for the heads up but I was aware of the two different lowering brackets. One for floor mount and a set for slider mounting. I have the BK 9078 and 9079 brackets made to mount to the GT3 seat sliders.

I did notice that now my seat belt buckle recepticle is now squeezed tight between my seat and the center console tunnel for both seats and sits lower as well. It used to stick up about a half an inch above the side of the seat and it used to have space on both sides of the recepticle bewteen the seat and the center console. The bolt that anchors the seat belt recepticle to the side mount bracket must be lower than on the stock brackets. I think this is why I was having a hard time with the seats going in. The seat belt recepticle was hitting the center console and keeping me from being able to slide the seat over enough to line-up the holes in the slider base with the holes in the floor.

yeah those are the same mounts I used on both seats and still use on my passenger side... they fit... its just a tight squeeze... really tight...I got frustrated too, but it worked... you may have to mount the brackets without the seat in them... then squeeze the seat between them and fasten it... you could also try mounting the seatbelt receptor with a bolt and backing to the tunnel... much like a lap harness would be on a 986 or 996 race car...

Oh I finally got them in. It was just a lot harder than I expected. The GT3 seats went in fine last month before I tried the lowering brackets.
