By decreasing the weight behind the rear axle you reduce that part of the force vector sum. Meaning the front actually has a greater force on it, since the moment around the rear axel must still be 0.

Greater force on the front, more spring compression.

Just no. Less force on the front. Your are overcomplicating the reality of the situation. The entire suspension supports the entire vehicle. You simply cannot separate the front and the rear of the car and assume they do not interact with each other. I removed everything behind the front seats, believe me it lifted the entire vehicle.

We are not talking about lifting the car inches, just fractions. Usually that is all that is needed to not scrape on most surfaces.

I am not over-complicating anything. Just using basic statics to explain why, when you remove weight from behind the rear axle, the front axle has to support more weight. Not much more, but more nonetheless.

Any weight removed from between the axles will raise the entire car.

Here's an experiment you can run. Take a 12 inch ruler, support it at 3 and 9 with pencils. Add coins to one end. Eventually the ruler will tip if you keep adding coins right? That means the opposite pencil is no longer supporting any weight. Reverse that finding and as you remove weight (coins) from one end, the opposite pencil is supporting more weight, even though the overall weight of the ruler is less. If your results differ, please let me and the world's science community know.

I don't need the body kit stuff, actually think it's kind of ugly but, springs, shocks, wheels/tires and some driveline modifications so it doesn't tear itself up are the plan. I love ripping around with this car on dirt roads and at this point without an infrastructure rebuilding plan the regular roads around the northeast are hammered and just going to get worse so it would be fun to be able to just roll without worry.

+1. That’s what I do. But I use the STI lip due to its strength/flexibility.
