this made me think about something--do you think that with all of the aftermarket modifications some of us do, we are significantly changing the front/rear weight distribution of the car, which is 50/50 in stock form? if so, do you think it has a negative effect?

I thought it was actually 51/49. Close enough though, eh?

and if you're that concerned about it, get corner weighted.

meh, not really concerned. j/w

Rashad, collectively, I believe one can, however, most folks that are doing typical street mods(exhaust + FI) never track, so it really doesn't matter. But if that scenario played out AND the person were driving the car to the limits, I believe it would have an effect.

Spare tire removal/jack/tools and lighter exhaust can reduce weight by maybe 40lbs over a typical lightweight dual exhaust. Add 70lbs to the front for a sc'er setup with aftercooler. That's 110lbs of weight being redistributed. removing the softtop is also to the rear of the center point. That assembly is maybe 40lbs(with motors). So that's potentially 150lbs of weight shifted.

At 2800lbs starting weight and a 51/49 balance, in the simplest of math, the front would weigh 1428 and the rear 1372. Add the sc'er to the front(70#) and you're at 1498. Subtract the 80# from the rear and you have 1292. Total weight: 2790. That ratio now looks like this: 53.7/46.3.

Granted the addition of a hardtop will replace some weight back onto the car, but it's close to the center. The weight of the sc'er is farther away from the "fulcrum" than a top, but similar in distance to the exhaust mufflers(heaviest part of the stock exhaust).

I cannot quantify the change in balance, but most folks would probably never notice the difference. Braking will be affected by the effect of the shifted weight, that's fo' sho'. I know this from personal experience.

interesting. i know i'd probably never notice the difference, but was j/w. and although you mentioned the blower and lighter exhaust redistributing weight at about equal distances from the fulcrum, wouldn't it also matter that they're at different vertical differences from the lowest point?? again, i'm just making observations. i'm sure i'd never notice the difference in my everyday driving of the car.
