I'm not finding the information I was hoping to on this forum so I figure I'll just ask. I'm looking for a track seat that'll fit my larger frame and fit in the MCS. I recently had the opportunity to try out Sparco Evo 3 seats, they fell great, but I'm concerned the shoulder support/wings will be too wide to fit in the MCS itself. Anyone have any suggestion for larger track seats that will fit in a cooper?

 

It will be. I have the Evo and the shoulder support rubs as is...

EDIT: Oops... you're talking about R53...

 

Have you considered a Schroth quick fit pro instead?

I'm assuming you are trying to keep yourself from sliding around

A Schroth quick fit/pro will keep in your place while also having the comfort of your stock seat and rear seat capabilities

 

Also consider reupholstering the existing driver seat to add more support. This keeps the airbag too.

 

That would be really expensive vs a plug and play harness

 

I was thinking in addition to the harness. I have the Schroth Quickfit MINI Racing Harness and while it certainly helps, additional bolstering in the seats would be most welcome.
