Drop that weight even lower!, Slim Fast for my car? Options

[Milds3vn]

I know our cars are already very light but since im at a big power disadvantage with my 7AFE I wanted to take it a step farther and get really light. Im not sure but I was thinking of ripping out the back seats for starters and some of the sound material. If I get Sparco seats or something, are they lighter than stock and by how much? Anyone know what else I can get rid of to lighten my car. I'm willing to take alot out, not the AC and heater and radio though I need music and the proper climate to pilot my lil bullet....Any suggestions would be awsome....

If you really want some power/weight ratio improvements, i would have to say go for engine mods, then for weight remove your backseats, spare tire/jack, and A/C unit- this weighs alot, and you could probably make due without it if you dont mind......i dunno about power steering, it probably weighs alot, but if you took it out you would lose pretty much all of youre steering response, like driving an old truck or something........and maybe some other non-essentials, but only take out what youre willing to lose in youre looks for the interior.
