Second Gen. Aftermarket Parts and Upgrade Guide (V.2)
This is a guide I’ve been throwing together representing the aftermarket support for second generation (1995-1999 USDM and 1993-1998 JDM) Subaru Legacy/Outback.
while everything hyperlinked is fully compatible with your 2nd gen, keep in mind that it is only a guide to give you a better idea of what to look for..
H&R (-1.5”, -1.25”)
RS☆R (-1.25”,- 1.25”)
KYB GR-2 – 10% Stiffer than OEM Struts
KYB AGX – On-Car Adjustable Damping
K Sport Kontrol
KW Suspension Variant
Rear Suspension Spacers – Cures the ‘saggy butt’ look after lowering your car, 3/8” Recommended.
Front Strut Tower Bar – Reduce body flex by providing extra stiffness between the strut towers.
disclaimer*- make sure to purchase MY93-01, or any with low-profile brackets.
Rear Strut Tower Bar -Especially effective in wagons
Front Swaybar – Reduce body lean and increase body roll resistance by upgrading to larger sways.
*In order to use 93-01 Impreza RSB, you will need to modify your fuel tank
Front Endlinks - increase swaybar effectiveness by upgrading to endlinks with less flex than the rubber OEM.
Bushings - help reduce drive train flex, eliminate chatter, missed shifts, etc.

Control arm - lower inner rear
Steering - rack & pinion mount
Sway bar – link (Front)

Trailing arm – front
Trailing arm - rear
Shifter Bushings - Improve shift feel and responsiveness on your vehicle by eliminating the soft rubber factory bushing
Front / Rear
Transmission Crossmember Bushings - These bushings can take the torque and vibration of high-performance street and race use
Sway bar Mounts - Super rigid forged light weight alloy mounting.
Rear Sub-frame Locking Bolt Kit - These bolts lock out the rear diff. sub frame bushings to maintain alignment under extreme conditions.
Aluminum Control Arms - Reduces your un-sprung weight and deflection under hard cornering resulting in improved handling
Control Arms - Lighter weight aluminum control arms from GC chassis imprezas bolt right up
Castor Kits - Adds caster to the front wheels giving the car more turn in response
Brembo Slotted , Front / Rear
Stoptech Cryo Treated
EBC Greenstuff – Designed to reduce heat and dust, best for daily driven cars
EBC Redstuff – Designed for a mixture of track and daily driving
EBC Yellowstuff – Used primarily in heavily raced and tracked vehicles
SS Brake Lines - Improves pedal feel and response
Speed Bleeder - Allows brake bleeding to be easily done by only one person
Master Cylinder Brace - helps prevent flex among the master brake cylinder by adding more holding points to it
Cold Air Intake – the Ebay intake was dyno proven at about a 6hp gain over similar Cosmo Racing ($200+) intake systems
MAF Adapter – You’ll need this to affix the cone filter to your MAF
Muffler - Anything works here
Borla UEL Headers - Not recommended due to the thin walls and chances of cracking
Borla Replica Un-Equal Length Header – Bring out the boxer rumble and free up a few HP. Much better reports than original Borla’s
OBX Equal Length Header – Sacrifice some of your rumble for more performance gains.
Header Heat Wrap – Keep the exhaust hot and the valve train noise muffled.
High-Flow Catalytic Converter – Increase exhaust flow
Camshaft Grinding - Low end gains and high end gains depend on how you want them grinded
Spark Plug Wires -
Lightened Flywheel - Reduce weight and inertia for better engine response
Grounding Kit – Smooth out idle and ride, reduce noise, and free up some HP.
Engine Management – Optimize engine performance by controlling aspects such as fuel mixture and ignition timing.
Port and Polished Heads - Reduce the restriction in the engine's intake and exhaust chambers to allow more air into the system, gaining power.
Engine Pitch Stop - A mount that’s stiffer than stock will reduce the amount of forward and backward movement the engine has.
Roll Center Adjuster – For lowered cars, this replaces ball joints ad returns the control arm angle closer to stock to help bring roll center closer to CG.
Phenolic Intake Manifold Spacer - Greatly reduces the transfer of heat from engine to intake manifold thus reducing heat soak. Every 5° temp. drop = 1% power gain
Transmission Mounts - Transmission Mounts Make the transmission more solid. They will give you better feel for your transmission and easier shifting.
4EAT / 5MT
Transmission Oil Cooler – Improve overall performance, and lengthen the life of both the fluid and tranny
Engine Oil Cooler - Reduces oil temperature for extended engine life
Short Shifters -

great list man, I would like to help add some stuff such as sterring wheel selection and to add/change the seating, wrx changed its seats for the 04-09 models, they look just like the sti ones but they are all black same direct bolt on like all the other subaru seats. I will have these installed next week and I can take a picture for you.
Can you make a Steering wheel section as people would might like to upgrade to wrx steering wheels or sti steering wheels or even the jdm steering wheel if u can find the clock spring for it.

this is awsome... add a brake section!! and tire faq. and links to the other stickys. also add a bulb guide. and more piggy back options
Great job bro!! All those strut tower braces fit? I will need to change my rear strut mount studs to longer ones. I have the 3/8 spacers on there. I thought I was looking at 100 each for those bars!!! You are the man dude!
I gotta find someone who will make a cold air intake for me. As far as exhaust im definately getting those hi flow cats and borla replica headers. Really gotta make that boxer engine rumble
Just ordered me some strut bars!!!!
