BASE OR SIDE MOUNT­ING

Fast Ford - - All About Seats And Harnesses -

Base-mount­ing works well on road seats like the af­ter­mar­ket re­clin­ers be­cause it means a slid­ing sub­frame can be used to ad­just the seat back and forth. In mo­tor­sport ap­pli­ca­tions this is not per­mit­ted, and by mount­ing the seat by its sides rather than the base pro­vides a stronger, more rigid mount­ing point (as the seat is ef­fec­tively sunk into the mount­ing points rather than sat on top of it), and it also al­lows the seat to be mounted much lower than a base-mounted seat, which is good for giv­ing the driver plenty of space, es­pe­cially head­room whilst wear­ing a crash hel­met, and helps keeps the weight and cen­tre of grav­ity lower too.

On side-mounted seats the seat mounts them­selves also play a cru­cial part in driver safety, not just by se­curely hold­ing the seat where it should be but by ac­tu­ally strate­gi­cally de­form­ing to slow down the im­pact and ab­sorb some of the en­ergy be­ing trans­ferred to the driver.

Most af­ter­mar­ket bucket seats are side mounted for in­creased strength
