Default Group A Performance - Endlinks/Pulleys/Sub Frame Locking Bolts/Pitch Mounts/ETC

I got a bunch of parts from Group A Performance this past week to throw on the car, figured I'd give you all a first hand review of each part as I get the chance to install them.

They carry some quality looking parts ranging from endlink upgrades, to aftermarket pitchmounts (like beatrush), to lightweight pulley kits, to even subframe locking bolts like the whiteline units. According to their website, looks like they've got a few more items in their R&D stages. So far, here are the items I got:

Front End Links

First Impression
The first thing I noticed with the new V2 links was the satin black anodized color. Visually, the links look more appealing than their colored V1 counterpart. The blue cast urethane bushings are a nice addition to the overall visual appearance of the link. All the bushings are pressed in.

In addition to the links, a complete hardware kit is always included with each box (bolts, washers, nuts). Bolts are plated black for extra corrosion protection (as well as a nice match to the black links). All metric hardware is classed 8.8, which is similar to a standard SAE grade 5.2 bolt.

Overall Links


GC/GM/GF/GG and GD Fitment






Rear End Links

First Impression
Similar to the fronts, the rears are a new black anodized color with blue cast urethane bushings.

A complete hardware kit is included in each box (bolts, washers, nuts). Bolts are plated black for extra corrosion protection (as well as a nice match to the black links). All metric hardware is classed 8.8, which is similar to a standard SAE grade 5.2 bolt.

Legacy/Forester

Pitch Mount

First Impression
Designed as a replacement for the stock plastic unit (which has a tendency to break), these aluminum replacements are supposed to be a direct bolt on. The part is a standard 6061 aluminum machined piece with black cast urethane bushings. It’s got a nice bronze anodized coating on it. No hardware is included with this part, it looks like existing hardware will have to be re-used.

Overall

Sub Frame Bolts

First Impression
Like the Whiteline units, these units are designed to lock the rear subframe and keep the alignment steady during race conditions. Unlike the Whiteline's, these are a 2 piece unit. Designed to be zinc plated sleeve that slides over a standard metric class 8.8 bolt.

Lightweight Pulleys

First Impression
Super slick pieces, I can’t wait to throw these items on the car. Designed to remove weight, which should free up some ponies and help the car rev up quicker (the crank pulley is super light compared to a stock unit, I still have to pull the alternator one to compare it to the Group A part). Looks like the power steering pulley is still under development, the bronze anodized finish should add a few points to the engine bay.

Throttle Body Spacers

First Impression
I’ve got to see how these all fit up, there is a big difference between the Pre-05 cable throttle bodies, and the 05+ Drive By Wire (DBW) throttle bodies. The pre-05 is a complete kit with hardware, brackets, and an OEM Subaru throttle body gasket (which is nice). I will be testing this out with a COBB Cold Air Intake to see if there will be fitment issues.

The 05+ is a full assembly with spacer, o-ring, and hardware.

Can't wait until a group buy comes out for the Muffer Bearings!




Is that price for the set or do I have to buy the front & rear bearings separately?

LOL @ the muffler bearings!

I have all the same stuff from Group A. First thing I got from them was the endlinks. They were such quality pieces that I've been slowly buying whatever they make for a number of reasons, price, quality, worksmanship and actual results the give me.

Update:
Installed the DBW TB spacer on a 07 2.5i tonight. Easy as pie. Write up and pics to come once they're uploaded.

Our pre-DBW install is on hold as one of the throttle body bolts seem to not want to come out (looks like it's corroded onto the steel insert in the plastic intake). I hate plastic intake manifolds. We're going to be installing the spacer with a COBB CAI. I don't see any fitment issues.

05+ DBW Throttle Body Install - 2007 2.5i

We used the instructions found on the Group A Performance website

2005+ Drive By Wire Throttle Body Install Instructions

Install

We started by removing the stock airbox on the car. There are 2x 10mm bolts that hold the airbox onto the engine, take those off. Remove the PCV hoses from the side of the airbox (held on by clamps) and the hoses on the front of the airbox to allow the airbox to completely come off. Disconnect the corrugated tube by using a screwdriver to loosen the clamp.




With your new found space, remove 4x 10mm bolts that hold the throttle body in place. I decided to unplug the harness on top of the throttle body to gain a little bit more room.




Prepare your new Group A Performance throttle body by applying a little all purpose grease/vasaline/anti-seize on the o-ring seat. This will keep the o-ring gasket from falling off.



Place the spacer betwen the throttle body and intake manifold. Ensure the orientation is correct, as vacuum leaks will occur (car idle will fluctuate) if the spacer is installed incorrectly. Replace the bolts with the longer 5mm allen head screws that are provided in the kit. Do not over tighten as you will strip the threads on the manifold.



Reverse all the steps to get the airbox back on. You will need to bend the 2 airbox mounting brackets back to accomodate for the larger spacer. No issue after install.




Currently awating feedback from the owner on milage and road feel.

Intake Manifold is the stock 07 2.5i unit, my test mule was a bone stock 2007 2.5i impreza.

Just finished another one for all of you =D

Onto the next big ticket item, Engine Pitch Mount

To access the pitchmount, the following needs to be removed:

TURBO APPLICATION:
Remove the 2x 14mm bolts holding the topmount to the brackets.
Remove the BOV (2x 12mm bolts)
Remove the 2x clamps holding the inlet hose to the throttle body
Remove the c-clamp on the turbo



N/A
Remove the 2x 14mm bolts holding the airbox in place
Remove the intake tube from the airbox
Remove the 2x vacuum lines from the airbox
Remove any supporting hoses attached to the airbox



INSTALL
From here, the pitchmount becomes visible. I followed the instructions posted on the Group A Performance site. I suggest using some white grease on the bushing ends as it gets a bit tough to move the unit around to line up the holes.

Pitch Mount Instructions

Remove the bolt by the firewall (14mm) using a socket or wrench. There is a welded nut on the other side



Remove the bolt on the transmission. Use a 14mm socket and wrench to work the bolt out. If there are any A/C lines (like me), remove those as well to get better access to the mount.

Here's a comparison of the 2. Same center to center dimension, just much nicer and robust compared to stock. Bushing widths are the same



Reverse the install (ensuring you install the larger end on the firewall side). Torque down to the following spec"

45 ft-lb on the firewall side
38 ft-lb on the transmission side

This is the unit installed on the RSTI. Perfect fit

02+ Front End Link Install

Test Mule - Riv's 02 WRX

Start by applying lots of WD-40 or any type of penetrating lube onto the bolts, they tend to be seized. Let it sit for 10 mins.



Using a 14mm deep socket, begin to loosen the top and bottom bolt that holds the link to the A-Arm and Swaybar.


In our case, the stud on the endlink kept turning, and wouldn't allow us to remove the bolt. We loosened it up enough to get a set of pliers in betwen the link and bolt. Once we held it tight, the nut started to spin again allowing the endlink to come loose.



We began to put the Group A endlinks together. We quickly noticed that there wouldn't be enough thread left past the nut on the top bolt (sway bar). We decided to remove the one large washer between the urethane bushing and swaybar to gain a min 3 thread clearance past the nut.



The new bolts are 17mm.

Our washer sequence went as follows (going from the inside of the car to the outside). This sequence was used to gain a min 3 thread clearance on the top nut.

Top - Bolt, small washer, swaybar, endlink, large washer, nut
Bottom - Bolt, large washer, endlink, large washer, a-arm, small washer, nut

Torque to a factory spec of 33 ft-lb

Here's a comparison of the 2 units.


Very easy and straight forward to install. I can't wait to do mine soon!

Wow nice write up. I think its a great way to promote your products. Ive ordered and installed the pitch stop mount. I have the black anodized unit. Ill post pics of it when i get home. Great quality and great prices. Im very happy with the product.

So far so good, i noticed you posted the torque specs for the bolts. I think i need to go back and torque them to spec. I just tightened them to german specs (lol). No extra NVH at all, and shifts feel tighter. The on/off throttle slop is reduced at low speeds.

Will definitely buy more products as you release them.
