NC Miata "Wide" Race Seats

My brother is doing a fair amount of HPDE in his NC miata, and is ready to move to 6 point harnesses. He currently runs a full stock NC with the exception of a hard dog rollbar and square NT01's along with some upgraded sway bars.

Going to say he is 38" waist, 5'9" and around 235lbs with some belly meat. 

Any advice on a comfortable seat for someone not looking to move into racing, just wants to strap in better and add a bit of safety to a stock car. Seat needs to be on the wide side and ability to still drive to/from events is important (so nothing too deep). 

Thanks in advance! 

About the biggest seat you'll find is the Sparco EVO 3—I've got a set in the vette and they're comfortable.  

I don't think these are the same model I have, but they're close: https://www.definedusa.com/Sparco-Evo-III-Competition-Seat-XLarge-p/008361fnr.htm

Thanks! Looks like Evo II US is the largest that will fit in the NC. May need to have him try those but open to any other options for 38" waisted big boyes.

If he's open to an aluminum seat, Track Dog Racing has theirs, which was specifically designed to fit into smaller cars (it has less wide shoulder wings): https://trackdogracing.com/TDR-RallySport.aspx

Any thoughts on a folding seat that accomodates 6 point harnesses? He would be best off in something low bolstered I have a feeling....

I have a set of Corbeau FX1 fixed seats in the Manic Miata.  The PO definitely had them in an NC before I bought them, and I believe they are the wide width version.

I'm 5'-10" and 265, with broad shoulders.  They fit very comfortably, work with 5-pt / 6-pt harnesses, and are pretty nicely made for the price point.  I recommend them.

The wide width looks pretty good. Will do some checking and see if he would be up for a fixed back seat.

I can double check that mine are the Wides, but I believe they are.
