No easy way on taking the back seat out, only 1 way.

If you're looking to loose some weight on the car, there are lots of stuff you can do.

Spare Tire & tools
Spare Tire Cover
Back Seat
Trunk Hatch Cover
Driver & Passenger Side Panels
Rear Speakers
Rear Seat Belt
Rear Wiper
Glove Box
Floor Center Console
Passenger Side Seat
Lose some weight

Lots more....just take out whatever u can and the car still moves.

With the spare tire/tools/cover, back seat, and rearside panels all gone the car went a whole lot faster. Tooked it all out when I sound proof the car.

You can also take out the sunroof and replace it with a carbon fiber piece. And drive on a close to empty tank of gas;)

Yeah, and if you take that heavy ass engine out, the EP will be much much lighter!! :D

I chopped mine from the doors up. No more heavy glass, roof, etc. Sorry no pics. My digital is broken.

Yeah, I'm joking. I didn't think anyone would take me seriously, but now that I reread it, I guess I should've added a lol or something.

bumper covers, bumpers, change your wheels to blackies or jus get ultra lightweight 15"s, center console, dash, anything plastic really... take off trunk, all glass, better yet, chop the top off... basically anything that doesnt have any true mechanical function that helps move the car can go... i remember some mag did this to some sentra a while ago... stripped it as much as stripped could be to gain like 15 hp or something lol

naw, seriously, like raiyo said... but also heater core, ac, plexiglass replacement for any glass pieces, and removing or changing out that black layer on the bottom of the car will help lose a lot of weight too... wait... we dont have that do we??? well like stated up above, lighter wheels deffinately help.

who's got the formula for weight loss to hp gain?

who's got the formula for weight loss to hp gain?

Car weight/hp = X lbs per HP.

You don't actually gain any horsepower by droping wieght.
But losing X lbs off the car from the above formula is the equivalent of adding 1HP

Randomish numbers here:

2800lbs/ 150hp = 18.66lbs per HP

So with these numbers you have to take 18.66lbs off the car to get the effect of adding 1 HP.

hmm... weight to power ratio... nice. but im talkin bout another formula... it breaks the car down into two pieces: for front wheel drives, its before the front windshield and after. the weight you lose after would give you more of a "gain" as opposed to the weight before since you're pulling weight with a front wheel drive. and before the windshield doesnt make that big of a difference because its above and before the wheels... kinda like taking a shopping cart and filling it up so it's pretty heavy, then pushing or pulling it to feel the difference... pulling the cart, it should seem heavier... so thats why losing weight after the windshield makes that much more of a difference. and then there's something about weight behind the rear wheels... dont remember too well... been a while since i really cared

I would think you would want to take everything you can out of the car behind the front seats. Anything in front of that helps traction (more weight pushing down on those wheels). Thats part of why i dont get people putting carbon fiber hoods on.....

F=MA or A=F/M (Acceleration = Force divided by Mass)

Achieve better acceleration by increasing the Force (engine power) or reducing the Mass (lose weight). I don't know if I buy into this before and after the windshield thing, no offense. There are some variences to this basic formula when you talk unsprung weight though (ex. weight of the wheels), but I don't think it matters where the weight is in your car (whether your pulling or pushing). It would definately have an affect on handling and traction characteristcs though. Could be wrong, I was a EE not a physics major. :)

Yes, with the F=MA formula, taking any weight off the car has the same effect, no matter where on the car it is.
Where the weight is removed will have a effect on the balance of the handling (cross weight forces, weight distribution etc) and traction. So you would want it to balanced for overall optimum handling.
