Driver Seat 2007 650i Convertible

Just bought an amazing 2007 650i convertible. Both my wife and drive the car. Even with the highest setting of the power seat my wife still needs a pillow to see properly over the dashboard. Can anyone suggest anyway to raise the driver seat by 2inches or so. I am thinking that I may be able to remove the driver seat and build two custom (may be aluminum) rails that are about 2" thick and install them under the seat rails. Anyone know of custom shop that may do this kind of work?

The seat only has to be raised one side at a time. You could use a 2x4, or have some steel flat bar cut & drilled. At this point you will need longer bolts. I would also have some concern about safety issues. Why not try using a foam seat on top of the seat, this way it could be removed if you want to drive.

I would go to a machine shop and have them make up some brackets similar to the aluminum billet brackets used for racing seats.

Here is an example of something similar to what I use to mount my Sparcos in my M3.

You use the OEM bolts to attach the spacer to the floor and then a new set of bolts to attach the seat to the plate. In your case you want a thicker bracket with drilled threaded holes just in front of where the stock OEM bolts go into the floor. This will raise the seat and move it forward about an inch which is not a big deal since you can still adjust the power seats to move up/down forward/back.

Make SURE you use the same high grade bolts as OEM - bolts specifically designed for attaching racing seats to the car - you do not want the bolts to shear in an accident.

Thanks yogi for the reply and the link.
After looking at how to remove the seat and looking on line for the parts it looks like the rear end of the OEM mounts are bolted into the chassis while the front end is secured with a nut that's covered with a round nut cover. Is this what you had in you M3?

My M3 uses 4 bolts. I move the seat forward and remove the rear bolts from the rails then move the seat fully back and remove the two front bolts. Then disconnect the wire harness.

I've never removed my 6er seats but looking at the TIS instructions I think they are the same as the M3. Under those front caps are bolts, not nuts according to the TIS.
