I am asking because I need to install 4 or 5 point harness to keep from sliding all over the damn cockpit.

Where do you mount the shoulder straps in a vert?

 

Harness bar?

 

No place to mount one in a convertible? These will be used ONLY for autocross, street driving I will ONLY use the factory equipment.

I see that Schroth does have a setup to work, since I am NOT going to use it on the STREET?

I do hope that is enough emphasis.

I would consider replacing the leather seats, however Mamasan likes her leather seats heated, so replacing the factory leather is NOT an option if she loses her heated seats.

 

Having one made (or a roll bar) may be the only option, for safety.

I remember reading about something that would allow you to lock the factory seatbelt for autocross.

 

GLok. They are backordered 180 days. I checked. Dammit.

 

Look at Corbeau. There are a few seats that have the option for heated seats. I will look real quick and see if I can find them.

EDIT: Looks like Corbeau's heaters can be bought separately and installed in any of their seats. It just requires removing the material and placing the heaters in place.

The A4s come with the option:

But here is the video on install for other seats:
