we just installed new bc racing coils yesterday, and i was reading somewhere that you need to tighten the bolts up when the coilover is loaded (aka car is on the ground) is this true?

also, is there a specific torque setting for these bottom bolts? we just did them as tight as we thought.

Doesn't really matter when you tighten the bolts for the coilover. Putting it on the ground wont effect tension on the bolt/studs.

When I did mine I just did them nice and tight so can't help you with the torque settings

well, the forum i did read it from was a STI forum, so maybe theyre talking through there bum lol

we did it to torque setting FT while the suspension was non loaded, and dare say it will be fine, but just wanted to check that it wasnt more serious since this is the first time ive done my own suspension

Prob 2 hours or so depending on your tools/experience

Need to take back seat out (for r33) and have an extra jack because you might need to jack the hub up.

FYI I had to raise the rears by 25mm and fronts by about 15 for it to sit nice and not scrape so maybe do the same before putting them on the car. Im guessing they ship them all the same way anyway?

Cool thanks.

My current wheels sit out the guards by at least 20mm, and right now its scraping around every corner that has a bump mid way. Well untill i get my gaurds flared anyway.

So how high do you think i would need to go? I was planning on setting it about 10-15mm lower than stock for now, then drop it once its been flared. Also will increasing the stiffness keep it from scraping if i keep it lower?

we did front first so...

-jack whole front of the car up so both wheels are off the ground.

-lock wheels one direction.

-undo bottom bolt.

-undo top 2 bolts.

-slide coilover out.

-reverse steps to install new coilover.

rear

-jack up rear of the car at the diff (make sure front end is down)

-take back seat out (can leave bottom part in the car to kneel on)

-slide parcel shelf out.

-take 2 brackets out that support parcel shelf.

-undo top bolts.

-undo bottom bolt.

-slide coilover out.

-revers steps to install new coilover.

job done. it was easier than we though, maybe 2 hours work?

to adjust heights

use general measuring skills on the coilovers.

-jack front of the car up so wheels are off the ground.

-undo bottom bolt and turn bottom section of the coilover up or down (after loosening the bottom location ring to desired height)

no need to take any wheels off for adjusting heights.

same with back.

Cool thanks.

if the guard is about 20mm higher than the tire when locked then it should be fine i think.

you may hear scraping noises, but make sure you check that its not just the inner guard scraping on the tire, it does this for me. fix = screw a self tapper in the plastic where its scraping.

increasing stiffness should stop scraping if the wheel is to big, if you hear bits of scraping as you go over bumps then yes it possibly will help

Finished installing them yesterday, took a couple of hours just cruising through it. Really easy job for a beginner wanting to start doing his own upgrades.

As far as heights go only had to raise the back 25mm, just like you said. But it scrapes when going fast with mid corner bumps. Have left the front the same height they come with no problems.

Set the damper to 18 front and rear, seems stiff enough and bearable ride quality for normal street use.

The only thing im wondering now is what i should set the camber too? And weather or not i need adjustable camber arms to reach that amount of camber.

youll need to replace the camber arm with an adjustable one. or you could get camber bushes from whiteline etc (check the whiteline website for what I'm talking about)

your rear wheels have a pretty aggresive offset dont they? might need to get your guards rolled or flared

U need to try an relieve the load off the bolt.

If ur strong enough try and lift the brake rotor/suspension slightly while trying to pull the bolt out.

If ur not strong enough the use a small jack carefully under the lower control arm. U need to jack it up just enough that the bolt will be relieved then u can remove it.

Its hard to remove because the suspension is hanging from that one bolt.

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 馃
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
