Suspension
Shocks, Springs, Coilovers, Swaybars, Strutbars, Stressbars

Issues and Discussion
General discussion on lowering Lowering for looks vs. lowering for handling,
the incorrect assumptions often made, lower does not always equal better, vehicle dynamics, etc.
The "LOW" thread Pictures and wheel well measurements of cars considered "low" along with what suspension and wheel/tire combo yielded it.
How does a swaybar work? What does a sway bar do? How does it help or hinder a car, how does it affect understeer and oversteer?
The Suspension Tuning Forum Discusssion of suspension tuning (lowering, swaybars, strutbars, springs, shocks, coilovers).
Oversteer vs. Understeer Always wondered the difference? Why are FWD cars associated with understeer and RWD cars associated with oversteer?
MKIV Suspension Geometry Thread Why a majority of the time lowering a MKIV gains you more in looks than it does in handling.
MKIV Rear Swaybar List List of rear sways for the MKIV.
Coilovers vs. Springs and Dampers Can a spring and damper setup compete with coilovers? Can coilovers compete with a spring and damper setup?
The Damper Thread How they work, what they do. Excellent general thread, but has a MKIV-centric view. You should read this thread if you consider yourself a car person.
MKIV Guide to Camber and Alignments What it is, what it does, and why we can't adjust it (Covers Front and Rear). Deals with why you can't perform a four wheel alignment on a MKIV.
Alignment Specs General alignment specs for MKIV's (there are variations, but all MKIV chassis cars should be within these ranges).
Coilover List

Can I just put lowering springs on my stock dampers/shocks/strut? It's not as easy as yes or not, but in the end, it's better to do it right the first time, read about the pro's and con's here.
Can I put a VR6 suspension on a 1.8t and vice versa? 2.0 and TDI? GTI and Jetta? Why there is nothing technically wrong with "mixing" suspensions.

Spring height comparison between OEM, OEM "Sport" and Eibach Pro-Kit springs

How To's
**Notice - The process for changing the suspension for any MKIV platform car is fundamentally the same. Therefore it does not matter if you are installing just springs, a cup kit, coilovers, a stock suspension, and if you are installing it on a Jetta, a Golf, a Wagon, a GTI, a 2.0, a TDI, a 1.8t or a VR6. Any suspension how-to is applicable. The same is generally true for swaybars and strutbars as well.
