Floor Crossmember

The car is going to be a rally car so will be having proper seat rail tubes welded in. Since the rails will be going in, would I still need the crossmember and have to fit the rails behind it or can I ditch it completely?

The crossmember is a very important structural component. Do not remove it.
In fact, in the 1960's for rough events the 'works' used to fit two crossmembers by welding a second one over the first one.

Strangely, there is a second one welded in behind the original. I assume it was for a base mounted bucket seat. Useless for me as it positions the seat far too high so that will have to be removed and then use a seat rail kit from Owens who are conveniently based up the road from me.

A lot of the circuit racing rules require the original crossmember. Adding a 2nd, double, crossmember is quite common as it's supposed to make the shell a little stiffer.
You're lucky to have Endaf so close - feels like driving to the end of the earth from me - I could spend hours just taking it all the cool cars he has.
Depending how tall you are, we ended up putting the seat mounts behind the crossmember. Do you plan on keeping the set on the rails?

As it’ll be a stage rally car, the seats can’t be on rails and have to be mounted using the new Motorsport UK type weld in mounts. Apparently the seat mounting kits Endaf sells at the moment will not comply for rallying but he’s apparently coming up with a new design. I haven’t had the chance to pop up there yet with all this corona virus going on but I look forward to it... I think it’ll be an expensive visit too haha

I’m 6ft so the rails will have to go behind the crossmember. I’ve cut the second one out as it would have been in the way.

A long time ago I tried this and it really makes the Mini, or at least feels like it makes it handle differently and not in a good way either, I found these amazing mechanical type devices called knees :)
