Sparco Touring Seat - can it be done

I have always suffered on the track because my helmet touches the roof quite a bit. Went out today and got a loaner sparco touring and it seems to fit ok, mayabe just some trimming in the front near handbrake cover. Will get some more mounting brackets as the lotus one’s wont do you can’t reach the handle for adjusting the seat length anyway.

Just a bit concerned that at the speeds we are currently doing the standard motorsport exige seat does not offer enough support, as well as not having space for the crotch belt. this seat also has the wings that wraparound, bit safer in my mind.

Anybody else fitted a seat like this that might be able to advise on perhaps mounting brackets that were used.

Thanks
