Adjustable runners - MSA Compliant

[smiles1]

Looking at doing a few 40 minute races with a friend (1 car 2 drivers) and the height difference between us both is considerable, such that adding removable padding will not be enough to allow a fixed seat to suit us both with a 1 minute change over.

I'm sure I'm not the first eprson to come accross this problem. Is there a way of having some form of adjustable seat runner that is still MSA (UK races only) compliant?

Thanks

Thanks for the replies. Unfortunately as I am tall if I use the standard runners it will put the seat to high up. Do you think the blue book wording would allow for modification of the original runners to sit them lower? Not sure which way to read it?

It does seem to say runners/seat combo....nothing to do with the floor they're bolted to.

So should be ok modifying that even if it is extreme

Thanks Stevie, now to dig out the old seat runners and see what can be done!
