"Chasis Bumpstop Measurements"
The picture above is a piece between the chasis and the rear upper control arm. Notice the "clean" area on the RUCA. I attempted to remove it but was unsuccesful. I am pretty sure it's bolted through on the top side of the chasis. Looks like I'd have to remove some bed panelling to gain access. I'm gonna try and pull some diagrams from Subaru to save me a bunch of time.

GD WRX Lateral links and End links selection
I'll be changing endlinks soon on the Foz and want to make sure I select a good compromise between something I can drive on the street, but feel confident enough to push it on a closed course when the opportunity presents itself. I will eventually upgrade the OEM lateral links (control arms) since I can run more/less rear camber if desired, not to mention set the car up for better rear traction when lowered.
There seems to be a lot of people buying more of what they don't need for their street cars. I see this in many car circles, it's not just a Subaru thing. While I'm all for tricked out race parts, there needs to be a happy medium for a car that is still driven primarily on the street. Running full "heim joint" anything on a street car usually sounds like a bad idea to me. That's just asking for too much NVH (Noise, Vibration, Hardness) and great way to make a new car feel old very quickly. With all the great polyurethane bushings available now days, why go through the head ache?
A good read on lateral links and endlinks, particularly what Jim from WhiteLine has to say on the subject. Read his responses on page 2: http://forums.nasioc.com/forums/showthread.php?t=453813&pp=25&highlight=spherical&page=2
Here is a decent install page I came across:

I will be going with flexible bushings on both sides of the lateral arm since this is still a street car. I've seen a few control arms that have a flexible bushing at one end and a heim joint on the opposite end. That would still probably be acceptable, but still more than what I need.

BGT vs WRX 4P/2P Measured
WRX 4Pot fronts PnP on BGT
WRX 2Pot rears however are not close at all.
2Pot distance between caliper bolts ~ 114mm,
BGT ~ 137mm
I need to get my hands on a 05LGT so i can measure their mounting points.
Also tried fitting impreza STB on BGT and it almost fit, but not quite.
I will be assembling my coilovers and doing an install in my next post along with the 4Pot fronts.

SUBARU SPRING RATES
Here's a link to Nasioc where they are listing various spring rates:
http://forums.nasioc.com/forums/showthread.php?t=695688
Our Baja and Forester aren't listed here so i will try to get that information shortly, along with these values:
1. Spring length
2. Coil Diameter
3. ID/OD top and bottom
4. Spring weight
Found curb weights to compare with also
BGT: 3610
LGT: 3365
STi: ~3300
06 WRX: 3192
FXT: 3310
Outback XT: 3500

More Rotor Research
Baja GT - 316mm Front and Rear
LGT Front
RB OE Caliper Rear Brakes with 2 Pot or LGT Caliper
If we wanted to do 4Pot WRX Fronts we would need to use
Front
2 Piece STI Rear Rotor Ring 316x20
http://www.racingbrake.com/STi_REAR_p/d205-01-311.htm
Then produce caliper bracket for 4 Pot and possibly use shims for the pads.
Rear

Intro: Two somewhat similar Subies, two different routes
While RG and I (VincenzoL, Enzochan, fchoncho, and OldSchoolJunkY on some of my favorite forums) will both be modding our cars in many similar ways, they will still be quite different. Similar in the fact that they both can accept many of the same mods since Subaru cars are notorious for their interchangeability with OEM components. The Forester is based on an Impreza chassis while the Baja is built on a longer wheelbase Legacy chassis. With my '08 Foz I will be lowering it the proper way, using all OEM parts to give it the ride height and correct suspension geometry of a GD chassis WRX, while RG will be trying to improve his suspension handling and still retain his Baja's higher ground clearance. Two cars with interchangeable parts resulting in two very different results. One for outrigging, the other for corner carving.

Introduction Junkyard Upgrades - Brakes & Coilovers
Enzochan and myself are going to begin documenting our OEM Junkyard experiments on this Blog site. We hope this will aid other suby owners in finding affordable mods at bargain prices. This blog site will not be open for comments, please feel free to send us an email and we'll be happy to incorporate your information with references.
I have a 2006 Baja GT, while Enzo has a 2008 Forester XT.
We did some bench testing on the internet and discovered this:
1. BGT - RimGuru has 294mm fronts, 290 rears. We know the 06+ WRX 4 pots fronts will bolt right up and now think the rears might also since it's the same rotor.
Baja GT has GD Impreza Front suspension, and BP Legacy Rear Suspension. This should be the same for all BH Chasis legacy as well.
2. FXT - Enzo has 294mm fronts, but only 266 rears. Therefore he will definitely need to buy some rotors for the rear.
I have some LGT Zeal coilovers on hand and am going to swap out the Front uppermount to make SUPER BOMB ASS COMFORTABLE ZEALS for my BAJA-RU.
Pics will come shortly along with measurements.
Peace, RG
