Rather than add FI to my cars and stress the engine/transmission etc. I prefer to reduce the car's weight to improve the performance. In the S, besides removing the spare tire/jack/tools etc. what else can be removed to make it lighter without removing the A/C (TX heat) and the radio?

Anyone know the weight of the spare tire and jack etc.? What is the weight of the motor for the power top? TIA

 

Ask krazik about this, his car is completely stripped and is naked.

 

i dont think weight reduction is gonna do much compared to FI
super street did a test on how much u gain from weight reduction
the results?
its not as much as u think it is

 

1 lb = .0021 in 1/4 mile (nice baseline computation which is about right with cars of this power to weight ratio).
IOW, remove 100-lbs and you should see a drop of .2 seconds in your 1320.
That's two car lengths (more or less) at these trap speeds.
The spare tire, jack and tool kit is around 30-lbs.
Tires/wheels is the first place I'd start if you're serious about losing weight.
The battery weight can be shaved (see s2ki.com marketplace), you can replace the seats with 12-lb racing seats, etc.
A titanium dual can drop another 35-40-lbs off the OEM system (52-lbs) or for even bigger weight gains, go with a single Ti exhaust.
I replaced my mirrors (fairly heavy...about 5-lbs each) and steering wheel (that air bag assembly is heavy) with a carbon fiber D-wheel.
Changing the OEM air box with an AEM, INJEN, etc. can save a few more lbs as well.
Then again, you're talking $2-3K if you add all this up (wheels/tires, cf mirrors, cf steering wheel, intake, exhaust, etc).

 

intake/exhaust/header.....saves a lot of weight

 

Russ, what wheels do you have on your car??? Are those Rota Slip Streams?

 

Yup, 16x7 ET45 w/ 205/50/16 and 225/45/16 Toyo Proxes T1-S (total tire/wheel weight about 33-lbs per corner). Tires are .8 inches shorter than OEM, the car has been lowered with a Tanabe NF kit (1.25-inches). Here's an older pic

 

Dont' the airbags weigh about 10-15 lbs???

 

-1 PRM Intake
-25 Spare Tire
-2 Trunk Trim
-7 Tools/Jack
-1 Mats/Visors
-30 (1/2 tank of gas)
-12 Optima Battery(see S2ki Store--easiest and cheapest way to drop a lot of weight
-15 Recaro SPG/Taitec rails
-5 Center Console
-10 Stock Rollhoops/Plastic (only take off of course if you go with aftermarket rollbar)
-2 Washer Fluid
This put me at 2734 with a ~60lb Bitterbar and Digrappa XBrace
Then I went with:
-1 Alum Pulleys
-30 Wilwood Brakes
-5? Interior Carpet
-15 Sparco + Taitec

A lightweight exhaust can drop another 20-30lbs easy. But with no carpet/sound deadening material it's wayyyy too loud.

 

Wow, thanks for all the input guys. Much appreciated.
