Weight reduction
You can achieve substantial weight reduction with the following modifications, while still having a car that's very comfortable to drive. Most of these modifications will directly increase (and decrease in a few cases) the safety of the car, while safety is indirectly improved due to the better handling and limits of a lighter car. Fighter pilots say "speed is life". Acceleration, deceleration, and lateral acceleration are all forms of acceleration, and lighter cars accelerate better in each of these ways because the tires have less mass to control....thus a lighter car is a safer car. Lighter cars have better moments of inertia which allows them to turn in more easily and roll less. Lighter cars are also easier on the tires and gas.
Stage I: Streetable weight reduction mods
Braking rotors with an aluminum hat, or titanium rotors (unproven on street cars) (~20-30 lbs)
Carbon fiber hood (~12 lbs)
(thinner) windshield and side windows (~5.7 lbs)
Non runflat tires (~20 lbs)
Slicks (~30 lbs)
Titanium exhaust (~35 lbs)
Long tube headers (~20 lbs)
Halltech aluminum alternator & bracket (10 lbs)
Carbon fiber driveshaft (~2 lbs)
Less options [HUD, elec AC, Active Stability, seat/mirror/steering wheel memory, cd changer] (~50 lbs)
Less gasoline & wiper fluid (No wiper fluid=9lbs, 6 lbs for every gallon of gas in that 18 gallon tank....~81 lbs for autocrossing)
Remove
cargo net
targa top (~20 lbs)
"appearance mods" - exhaust plates, doorsill covers, etc.
fuel rail covers
all loose change, CD's, golf clubs, misc. items, from center console, hatch area, and glove box
Replace
stock crank pulley with aluminum aftermarket pulley
steel dampener with aluminum dampener
stock targa top with lexan piece (coupes)
water pump with electric water pump
battery with smaller battery
non-stressed fasteners with aluminum or titanium fasteners
leaf springs with coil over shocks with titanium springs
steel shifter with aluminum shifter and delrin or titanium shift knob
Empty your pockets of extra change, PDA's, cell phones, keys, lead plates, or whatever other junk you lug around
Go on a diet
=p
Stage II: Hardcore semi-streetable weight reduction mods
Aluminum flywheel (~10 lbs)
Lighter clutch like Exedy or Quartermaster (~10 lbs)
Racing buckets (40-50 lbs)
Off-road x-pipe (10 lbs)
Replace stock hood, fenders, doors, roof, hatch and bumpers with aftermarket carbon fiber pieces
Remove
Floor mats
Fog lights
Stage III: Track only weight reduction mods
Racing steering wheel & delete both airbags (~30 lbs, but get a 4-6 point harness)
Use unpadded aluminum or carbon fiber steering wheel
Run open headers
Replace stock front and rear glass with polycarbonate “glass”
Rebuild motor with Al or Ti connecting rods, Ti valve spring retainers and pushrods
Port the heads
Replace valve covers with magnesium or carbon fiber parts
Strip entire car, acid wash chassis, put car back together.
Remove
Column locking hardware
Interior – passenger seat, carpets, speaker panels, head liner, dash, center console, glove box, door panels, sun visors, rear view mirror, insulation, etc.
A/C Compressor
A/C controls and ducting
AIR pump system

Reducing unsprung weight—not all is streetable
Forged 1-piece wheels
Use 3-piece wheels by Jongbloed, Kodiak, CCW, BBS
Skinny front wheels (drag only)
Ti fasteners on 3-piece wheels (~1 lbs per wheel)
Lighter non-runflat tires, or even track only synthetic corded slicks
Lighter calipers
2-piece, unvented or titanium rotors
Titanium wheel studs
Aluminum or titanium lug nuts
Remove tire pressure sensors
Remove rubber valve stem cap
