take those 17's off the front and put you stockers on the front, or some 15's, this help's alot, I weighted my car at the track a while back and it was 2527 with out me in it, getting the car down to 2200 with in it will be a good ideal weight ratio :cool:

i thought you would put stockers on the back and keep the fronts on cause the front is where you want traction?

Yes, but the 17s take more power to turn as well, even if they are the same weight, having mass further away from the center of the point of rotation increases the amount of power needed.

The weight to time off of the 1/4 isn't linear though. It is similar to how HP reduces time.

Like going from a 17 sec to a 16 sec 1/4 mile takes significantly less weight reduction and HP improvement, than going from a 13 sec to a 12 sec 1/4 mile.

Ever weighed the front passenger seat? Sucker is heavy (including the frame it sits on)
take out the Front/passenger seat, rear seats, all carpet/headliner/plastic inteiror pieces, spare tire/jack, winshield washer resivoir/parts, and a few other various parts you dopn't need to go 1/4 of a mile. I believe it. I took all that stuff out once, the weight adds up pretty fast.

Your amp and subs don't really count as a weight reduction seeing as they never came with the car in the first place. ;) You made your car slower by having some heavy audio equipment in the trunk, taking that stuff out brings you back to par. Weight reduction = any reduction in weight taken from the stock 'wet' weight of the vehicle. :cool:

So in reality you only lost ~68lbs.
