one that you bolt on to your bolt on cusco rollcage i believe. anyway back to the op. yes keeping your back seat will not only add structural rigidity but also gives you a +17whp. also throwing a jdm decal will add another +26whp… thats 43whp gain only with $5.00 cad. now thats really impressive for me dwag. ---

I still can’t get over, how you thought this was a legit question. More so because you own a 240 now. ---

lol alright I’ll explain myself, I got no excuse though. Back when I had my Saab, I wanted to take the rear seats out (and other shit) to make the car lighter. Someone told me that the seats and spare tire were actually part of the car’s structural rigidity (to a small degree). I removed them anyway, along with a bit of other stuff lol. Next track day, I went out, and I was inconsistent as fuck. Either 'cus the car was slightly lighter or 'cus of the shit i removed. I dunno I’m just overly sensitive to small changes in a car lol. BUTANYWAYZZ mx-5 got no rear seat so all mah troubles are gone 😉 ---

if you dont have a solid amount of trackdays or hard driving under your belt… its not necessarily that you’re sensitive to small changes. its more like your driving isnt consistent enough to form a valid assessment. ---

All you wanna do is model the rear seat frame and strut bar in NX or CATIA and whip up some finite element analysis. ---

Please somebody do it. I want to know if I should remove my front strut bar and install a foam seat to increase the rigidity of the front end. ---
