installing suspension...

[SLEEPERracer]

i was wondering if you need to torque down anything to a specific level when reinstalling the front strut assembly or anything in the rear. thanks!

[Dave]

yes, you do

[Brew]

yes, you do

Yeah, lugnuts. 90ft/lbs

Everything else should be be tight enough to not back out or cause play, but not so tight that you start breaking shit.
Although, since you're asking you probably should get yourself a Bentley manual, which has all of the torque specs you need.

Caliper bolts are 91ft/lbs, I always torque those to spec. Same with the wheel nuts. The top bolt for the shock is hard to torque to spec, and the control arm and tie rod ends I just crank down.

So true. I did not provide that as he did not ask for it. I answered the questions exactly as he asked it. ;-)

How do you know when you have the correct torque? A special tool/gauge?

wel i put the fronts in and it just raised the car. i dont think the coilovers i ordered fit the strut i have. i got the ones the fit oem and tokico shocks. what i have is an oem strut with a tokico shock. anybody could help me out cause i even put the lock on the perch all the way down and still the car was high. anybody have any idea whats up? thanks!

What coilovers are they? Spring lengths and rates?

i finished the job yesturday but wen i lowered the car from the lift it stayed high. like higher than stock or stock height! my spring rates are....


front-
GC150.64.66

rear-
GC140.64.83

Front: 6" spring height, 2.5" spring diameter, 375lb/in spring rate

Rear: 5.5" spring height, 2.5" spring diameter, 475lb/in spring rate

I dont have coil-overs but isn't the point that you can adjust the ride height? Try turning that collar down. Also dont you need shortened strut bodies for coilovers? No need to skylift your e30.

[Digitalwave]

You really need to cut the stock lower spring collar off of the stock strut tube and reweld the smaller GC perch if you want to drop the car down low.

You don't have to remove the calipers to do the front suspension.

Compress the spring on the car
remove upper mount
remove locking cap for strut insert
slide strut insert out through tower
replace spring with new spring
slide new insert in and tighten cap
install top mount
uncompress spring

job done.. Take about 30 minutes per side in the front.
