Is Weight Reduction REALLY that much of a difference?
When I got my Volks rims on I felt an increase in acceleration, which quite frankly I was not expecting. I drive my car a lot and I feel differences very accurately and I can honestly say I felt one from the new wheel/tires. The Volk wheels are 16.5lbs each while stock is 21lbs. Thats 4.5lbs each wheel ~ 18lbs all around!
I think something people always overlook is TIRE WEIGHT. The stock ADVANs weigh in at 25-26lbs. My 18" Neovas weigh in at 26lbs, so I didnt gain much weight. I checked out S-03s and they were 28lbs!!! Thats 12lbs total around the wheels of the car! Tirerack specs gives weights of tires, I suggest using it next time you look for tires! If youre gonna buy new tires why not buy light ones!
Im in the market for rotors, still havent found any for a descent price that reduces weight... anyone?

Guys this post turned into a mess. Everyone has a somewhat of an opinion or a joke about weight reduction. Some of this stuff about weight reduction is good but the majority of it are basically half A$$ explanations. Unless you do some hardcore racing please do not worry about weight reduction. There are guys out there that with 4 PhD trying to figure out the best balance for a car. Remember that an ideal car has a 50-50 weight ditribution which the Evo does not(it's 60-40), and removing weight from one end will upset some other variable on the other end. Just learn how to drive the Evo to it's limits on a nice track(not a drag strip) and then worry about making weight modifications to it(contact some professionals)....and yes weight reduction does make a huge difference in Racing(reduced lap times)....but not that much on the street. Drive fast and safe!....on the track
Why would one not want to work at getting the Evo closer to 50/50. Such as small batteries and relocation, A/C and power steering Removal, Carbon Fiber hood or fenders, Lighter wheels and Break disks. What variable would get messed up?

200lbs = .2s = 2 car lengths = smoked.

Weight reduction is the best performance MOD you can make, IMHO. It gives you better acceleration, better handling, better brakes, and better gas mileage. If the weight reduction is rotating mass, it is even better. If the weight reduction is unsprung weight, it makes the handling much better.

that said, the back seat stiffles a lot of noise and does not weigth a whole lot, want to make your car sound like a truck, pull the back seat out.
the carpet in the trunk of my car is nearly weightless, might be five lb max.
the bumper bar, small battery, spare tire, are the only clear gainers for most people.
Derek, what sound deadening material are you referring to.

There is material on the floorboards and under the rear seat. Plus there is also some stuff on the firewall in the back of the engine compartment.
My friends RS has none of the sound deadening material in these places.

Look on Buschur Racings site there are some light weight rotors that are not too bad in price.

YES! weight reduction REALLY makes alot of difference if you know what you're doing.
Here is an example.
Curb Weight: 2,762 lbs
1/4 Mile:16.3 @ 84.0 mph
60-foot:2.9 sec.
0-60 mph:8.6 sec.
Curb Weight:1,674 lbs
1/4 Mile:14.3 @ 93.2 mph
60-foot:2.6 sec.
0-60 mph:5.8 sec.

A lot of these suggestions might only be for a pound or two here and there....but every pound counts. When you start adding up 5 here, 12 there, 3 on that side, 9 up front, thats when you making a difference. Also realize some of these reductions should be left on the track and the track alone, such as removing bumper mounts and crash bars. Unless you fancy the idea of getting into what would have been a mild fender-bender and seeing your EVO crush like a Natural Light can on a frat boys forhead.
