Sparco Seats

Little by little the stang is coming along for track purpose, but I have Sparco seats which are quite tall for this car - theres about 2 inch or so gap from the top the seat to the top of the roof

so from what I've been able to gather is that I have to remove the raised seat pan?

If so, is it just a simple remove or does something else needs to be fabricated as a replacement?
How much structural rigidity am I losing?

I've made several attempts to find other threads discussing/showing how to remove them and so on.


Any help?

A 69 seat pan drops right in and is a bit over an inch shorter. No magic involved.

Couple of options, first do the 'vert seat pan for the added lateral structural support. This would also require vert inner rockers though which are also an excellent addition for longitudinal support. For the pan itself, Shaun (SorT) has a really good tech article on lowering the seat pan on his website. Option two, if you are doing a cage...which you should be if it is a track car...would be to eliminate the seat pans altogether and build a tubular structure tying both sides of the car together at the seat pan locations. Then add in adjustable seat plates front to back between the tubes at the seat locations. This way you can set the height at your discretion. If you check out the CA site, you can find some pics of this option.

Regards,
Patrick

It is not required to install the convertible rockers to get the one piece seat pan. They make the one piece seat pans for coupes and fastbacks without the need to install conv. inner rockers:

The 69 vert pan is 1" higher than the sportsroof due to the hump over the tunnel. I and others have cut and spliced the hump from the one piece conv seat riser to the stock 69 sportsroof seat risers. It's a snug fit at the inner seat belt bolt, but doable.

Cool. Didn't know they made that. Would still do the inner rockers however...for reasons listed. Even with a cage.
