I am a pretty big tall muscular guy too and a few years back my stock seat developed the gangster lean, and one day i was at a set of lights no other cars were around just me so the light tuned green and I stomped the pedal down and all of a sudden one front seat bolt snapped and went flying into the back seat and the other one got ripped out of the floor and broke the weld... and the seat then went back i was like WTF as I was trying to grab the steering wheel so I got the seat bolt hole support reinforced and welded up at a repair shop, then I decided to buy these seats
