Default BC Racing Coilover Install

Let me just say, these BC Racing coilovers are GORGEOUS!! Very high quality build that will take the pounding of the GrimmSpeed team car. I have heard/read alot of good things about these coilovers so i decided to pull the trigger and get them and i'm glad i did.
I went with the 8K/6K setup and also got an extra set of 8K and 6K springs so i can swap them out to see what the best set up is. These come with very strong camber plates and pillow ball mounts(soo much better than the stock mount). In the next few days we will be getting their prototype rear camber plate as well. They are 32 way adjustable as well.
Install went fairly quickly and there were direct bolt on to the 97 Impreza L. Below i have detailed step by step instructions.
If you are looking for a great street/track setup..this is it.

Installation
Tools:
12mm wrench/socket
19mm wrench/socket
Breaker bar(not needed but helps alot)
Jack
Safety glasses

1. The harderst part of the entire install will be breaking free the 2 19mm bolts at the base of the strut. You will want to soak these in liquid wrench/PB blaster for 1/2 hour+ before you even try to loosen them. After soaking use a 19mm socket on a breaker bar to bust the nut loose. On the fronts, the top bolt is the camber bolt, make sure to put this bolt back in the top spot when reinstalling.


2. Take off the brakeline bracket that attaches to the stock strut bottom. This is a 12mm bolt. See in pic above
3. Take off the abs sensor bracket. This is also a 12mm bolt. See in pic above
4. Now you will want to prop up the jack underneath the hub/control arm to hold the hub assembly in place. This helps not to stretch things out like your brake lines. Jack the jack up just enough to put a little pressure on the hub.


5. With the jack in place you can now take off the 3 12 mm nuts at the top of the strut/strut top. These arent torque'd down much so they will be easy to get off. Before taking the 3rd one all the way off you will want to be holding on to the spring because once you take this last 12mm nut off the strut/spring will come loose.


6. You have not taken the oem strut out.
7. To start reinstallation of the BC Racing coilovers slide the strut top into the 3 holes in the wheel well. You may need to spin the strut a bit to properly align the tophat studs. Once aligned, loosely place the 3 12mm nuts on top of the strut. At this point you can let go of the strut as it will hang freely.


8. Since the BC Racing coilver is shorter you will want to jack up the jack a few more inches to move the hub assembly closer to the bottom bolt holes on the strut.
9. Insert the 19mm camber bolt into the top hole, then repeat with the bottom 19mm bolt through the bottom hole. Tighten down nuts onto both 19mm bolts.


10. Reattach the abs sensor to the coilver with the 12mm bolt. See above pic
11. Brake line bracket. This is the only piece that didnt bolt directly up. You will need to get a bolt, washer, and nut to tighten the brakeline bracket onto the strut base because there is not a thread female side on the BC strut like their is on the stock strut.
12. You can now tighten down all 3 12mm tophate bolts.
13. Now rinse and repeat for the 3 other corners.

The install is very straight forward and should take you 2-4 hours depending on your experience level. You will want to play with the front top 19mm camber bolts to get the camber set to your liking.

I will be writing updates on these bad boys as time goes on so you can all see how they preform.

They already come preloaded, so you just have to put them in right.

the lower strut bolts are on as tight as i could get them with the 24" cheater bar. i didnt torque everything down to spec yet. i think the lower strut ones are something really tight like 150 ftlb

What rate extra springs did you go with? Both sets listed are the same. Please let us know what springs work out best for you.

I have these on my 05STi and I love them. The install was pretty straight forward but I ran into (1) bolt that didnt want to come off and ended up hacking it off and getting new camber bolts.

+11ty billion to Josh at Import Image for hooking me up with a sweet deal. I will try to find some pics of before and after shots.
