Weight balancing -- adding to the rear.

[HALO1]

Ok, guys. I'm by no means an expert here, so flame me as necessary.

When I was first designing my customer enclosure for my sub (figure 100lbs for the woofer, two amps, and enclosure), I was intending to make it fully removable for autocrossing (I race monthly, give or take, but have only been 4-5 times--still a newbie).

Then I drive my girlfriend's new (used) MR-2 (mid-engine car), and was simply impressed with the handling. Now, I know a lot of that was because of the car itself being WAY lighter, but...then I got to thinking about weight balance.

So, I thought...if I leave my sub enclosure in place, say 100lbs added to the rear of the car, and I don't care much at all about 1/4 times, will this help me, hurt me, or balance itself out in an autocross environment? I plan to do typical bolt-ons with a FP Big t-28 in the end. I will likely have a rear sway bar in place by the time I get the sub in.

Let me know your thoughts.

You'd do better w/o the 100lbs...

I'd just relocate the battery to the rear and pull the subs out.

cf hood and relocate, no subs.

Weight is the enemy of the race car.... Take the subs out (your gonna want your ears)
move the battey to the back and have fun... Then buy a lighter car to autox!

Some of the best autox cars are not 50/50 balanced.... CRX's, sciroccos and other small light front or rear drive platforms.........

I corner balanced my 92 talon Open class rally car and it was 2850 with cage, skid plate,
full sizes rally spare tire, and all other rally gear......

I wish some auto-x allowed lexan and CF hatches for porky cars.

An AWD car under 2500lb would kick ass.

yeah no kidding a 2500 lbs car would kick ass, my friend is actually about to start building a colt with a 4g63 conversiona and awd, i'll let you klnow how it turns out!

Less weight with a worse wieght distribution will have a higher limit, but may not be as comfortable at that limit.

That means it'll be a faster car, but possibly harder to drive on the edge.

If you want a better weight distribution, don't add weight. Move around weight that is already in there, and lighten the heavy end.

Buy a rulebook and look under F Prepared.
