Does anyone have some info. or advice for modifying the seats in a 993 to obtain more legroom? I am tall (6'5") and my legs aren't quite as comfortable as I'd like. Thanks. Paul <img src="confused.gif" border="0">

Paul,

The first thing to do is to use the rear bolt holes for mounting the seat. That gives you about 3/4 of an inch. Beyond that, I am not sure what to do since with that done, the bottom, rear part of the seat actually touches the base of the rear seats - No more room.

It is really easy to do, just make sure you use an allen wrench socket on a ratchet rather than a regular allen key. You will certainly strip the bolts if you don't. Once you have the bolts out, wiggle the seat a little so you can see the extra set of rear holes. This means that instead of using all 6 bolts, you will now only use 4.

It will make sense once you have it out - it is very simple.

Paul,

E.J. is correct. I am 6'4" tall and re-mounted my seats in the manner described. It took me about 30 minutes to do both sides using a metric allen socket and ratchet. The seat rails already have 2 sets of holes so moving them back is a snap.

The 3/4" move makes a big difference. I'm told that another inch or so is available but drilling and/or other mods are required.

Which bolts should one undo first? The fronts or the rears?

I too am 6"5' desperately looking for more space. Would putting the seat back like that not raise the issue of my head interfering with the sloping rough though? It already slighlty touches it now...

At 6'4", I'm in the same boat. Is it possible to ditch the sliders altogether and somehow mount the seat directly to the bottom rail? I realize this would mean I won't be able to slide my seat, but I'm the only one who drives the car.

It also helps to raise the front edge of the seat 1/2" to 3/4" by using spacers and longer bolts under the seat rails in the front. I am 6'3" and made this change in addition to using the rear bolt holes.

In the interest of optimal weight/power ratio, Porsche designed the 911 to eliminate tall (and, therefore normally, heavier people) drivers. Not providing enough leg-room was one engineering spec, low roof the other. They considered it the natural consequence of Darwin's natural selection process. As a purist, it is a shame to see the original design of the car (and the inherent balance) being tampered with... <img src="graemlins/roflmao.gif" border="0" alt="[hiha]" />

Years ago there was a VW Sterling Kit which required lowering of the seats by installing pans onto the chassis.

I suppose if one is determined enough a good body shop can fabricate pans to fit the P-Car. Doing somthing like this would be a bit extreme, but I guess you can gain significant headroom.
Also a possibility, Recaro seats might offer a lower profile.

Will,

That is the preferred method for us loarger guys when mounting racing seats. Buy the BK sidemount brackets with the racing seat and bolt it directly to the floor. I don't think there is a way to do this with factory seats though.

The guys at OG Racing know all this stuff and when I do finally get the race seats, this is how I am going to go.
