Need help with seats

[m1tch]

Hi guys, as you might have seen I have for sale some Kei seats as I will be getting some Bride seats in for my FC that come with the brackets and rails.

This is the first time that I will be putting bracket/rail combo into a car as on my mini it already had a subframe with runners on it that bolt into the car.

Basically my idea is to perhaps use the Kei racing seats for most of the time, and then bolt the drivers side Bride seat into the car for track days etc, both seats have harness points for the soon to be fitted roll cage.

Just asking about if its ok to do that, Will the Bride brackets on the Bride seats be ok to accept the rails on the Kei seats?

The Kei seats have runners on them, but not the brackets to bolt them to the floor, im not sure how the Bride brackets work, do the runners bolt onto the Bride brackets or do I need to remove the runners and bolt on a fixed seat?

Sorry if this sounds a simple question lol im just not sure how this seat fitting works regarding runners and the brackets.

Thanks for any answers
