I recognize those, lol. I'll tell you right now though, although more comfortable than the fixed bucket seats, those cloth 8 seats will wear you down on long road trips. They suck for auto-x too.
This may not apply to everybody, but Brian and I are roughly the same frame and the wide bolsters on the stock 8 seat don't hold me well under hard cornering. I need to fatten up
Oh - and since they're two piece, after a single season auto-x the two sections "knock" lol, I'm looking to tighten them up before next season or finally get a decent pole position in there.
Good luck with the install - should make the deals gap trip nicer, until you hit the dragon!
