MB965

I have a 964 C2 Turbo in which I am installing a pair of Recaro Pole Position seats, which are about 1 1/2 inch wider than the standard width of the SPG. (They are probably similar in width to the Sparco Evo 2's.)
The Recaro seat brackets which came with the seat are aluminum and stick out past the side of the seat by about 1 inch.
When I position the seat (with the mounting bracket attached to the side of the seat and on top of a set of factory sliders) the bulge of the mounting bracket hits the center tunnel forcing the seat to then be off center by about 1 inch. The seat needs to move toward the center of the car by about inch in order to be centered on the steering wheel.

The other problem is that because the seat and seat brackets are wider, the sliders do not line up with the factory mounting holes, they are about 1 1/2 inches too wide.

It seems that different seat mounting brackets which do not stick out past the sides of the seat and which also have a longer horizontal leg would solve the problem.

I am sure others have installed these wider seats in their 964/993, can you help me with some suggestions. I am also posting this on the 964 board.

Thanks,

Mike

You might want to check out the side mount brackets made by Sparco and Brey-Krause, to see if they stick out less. We used Sparco Evo 2's ( as you say, a relatively wide racing style seat), with factory sliders and using Sparco side mounts on an 85 Wide body with hardly a hitch. Re-using the factory sliders required some piece of the slider ( a center triangular piece) to be ground down, but other than that...went well. I believe the C2 series of cars and the 3.2's used the same seat spacing.

Brey Krause has side mounts that should work for you. Give them a call.

The 3.2's weren't designed for 4 wheel drive, and thus didn't have a major tunnel obstruction going down the middle of the 964/993 interior. Having installed SRD's in an SC and C2, the space is tighter in the C2 (although the rail spacing may be the same).

Mr. C4

Mike,

What about fixing the sidemounts like this

That should give you approx. 1" clearance away from the tunnel.

I recently fitted Sparco Evo2's and they bolted right in.

MB965, I FULLY understand your issue, as I have mounted Recaros, Sparco Evo IIs, Evos...and whatever else I've been able to get my hands on to "try out".

I "egged" out the holes in inboard set of brackets, basically making them oblong so they can be secured a bit away from the tunnel...this also butts the brackets up against the seat better.

I saw a guy with a 993 at Summit Point last year that had the brackets reversed, that is, mounted "flopped" when compared to how everyone else bolts them up, this afforded plenty of access to the allen bolts that secure the rails/brackets to the factory mounting points...I haven't tried this yet, but as Johannes alluded to, it's apparently an option.

Remember these brackets are truly "generic" brackets, made for a VERY wide variety of cars...it's not too "far out" to imagine that one would have to modify the brackets to make them fit correctly...after all, Sparcos, Recaros, Corbeaus and whatnot were NOT necessarily manufactured for Porsche - although we'd like to think they are! <img border="0" title="" alt="[Wink]" src="wink.gif" />

Thanks for the replies.
The mount is radiused outboard of the seat where it is bent at 90 degrees. It is too short (vertically) to turn around because the radiused part hits the seat.

The B-K mounts are specific for the Pole Position/911 so it looks like they will work. I couldn't find a phone number on the web site though.

I guess I did expect that the mounts would work for my application, although the guys who have done it seem to use Sparco or B-K mounts.

MB965...I think you've got my brackets and I have yours. I just installed a Recaro SPG in my 91. The Recaro brackets that came with the seat made the sliders to narrow. Ultimately, what we're shooting for is a cross car dimension of ~16 1/4" for the sliders. The brackets that came with my seats had them way to narrow. Sounds like they should have been on a wider seat like the Pole Position (35 mm wider at the hips I believe). I would recommend picking up some side brackets from Speedware ($99). Brey Kraus has them $10 cheaper but they're made out of steel. Speedware's are aluminum so you can save a few pounds.

Mr. C4

Jeff & Mike,

Its not the sidemounts that determine the width it is the width of the bottom of the seat and yes, the SPG is a very narrow seat. OK, to certain extent the sidemounts have an inpact on width but that can be drilled to match the mounting points in most cases.

Good luck!

BK doesn't sell direct, you have to buy through one of their distributors. I get my BK stuff through OG Racing (www.ogracing.com) in Virginia.

Mr. C4...well, I can say with confidence it's the side mounts that ultimately determine the width. The brackets speedware sold me were for the Pole Position, not the SPG. And they didn't work. Slotting holes to accomodating a 35 mm seat width difference isn't going to work. Also, the Recaro side brackets come with weld nuts installed. So these can't be slotted.

BTW...the Speedware brackets are already slotted.

MB965

I called OG Racing about the B-K Pole Position mounts. They were nice enough to get the bracket out and measure it for me while I was on the phone.
It looks like it will fit exactly, very cleanly and still have full adjustment. I was very impressed with OG's efforts at helping me out with specific measurements.
The Recaro dealer told I had to reverse the mounts and slot the holes, but it was still too wide, did not fit the seat all that well and it looked terrible. I'm sure you could cob up some type of poor fitment but that would be missing the point of installing a racing seat, roll bar and harness.
So I guess I have a spare set of Recaro aluminum seat mounts, anyone interested?

I thought I'd share more details on my lengthy seat install. I think Mr. C4 might be right. I spoke to speedware and they insist I have the right brackets for my car and seat (91 965 and the recaro spg's). I had a few issues with getting the seat to fit just right. The "universal" brackets speedware sells work for most seats, except the SPG (in my opinion). I took my car in and they're solution was...and I quote "you have to leave the side brackets loose, and then tighten them up after you get it in. The seat will flex to the brackets...". WTF! Anyway, the spg is in and I did get it to work with a little extra work. I made the slots a little bigger since I couldn't get the 16" x-car spacing.

MB965...what do you want for those seat mounts??

Anybody ever notice their seat is not centered on the wheel? My seat's about 1" outboard from being centered on the wheel. And since I've used up all the "slot" on the brackets. I can't adjust :-(
