FOR REFERENCE ONLY! USE AT YOUR OWN RISK!

20 ft lb KW camber plate torx

good info ... last picture, is it the rear part of the car ? is the 25ft-lb for the bolt that holds the rear shock ?

Correct to both questions.

was 45 ft lb for the front and rear sway bar? Awesome info BTW way thanks for the extra effort!

Excellent! Thanks for the very useful post. Appreciate your efforts.

Front only. No need to remove rear swaybar linkage.

DUDE!!!! You kick ass. I've been looking for this info forever! Where did you get the values from? Do you have torque specs for the rear install?

The last picture is the rear install. Couldnt really figure out one of them, but it was very tight, so tighten as much as possible.

So how did you come up with these values?

LOL ... sorry it's been a really long day. Haha.

When is the darn full shop manual going to come out? We should not have to go through such measures to get torque values. Thanks indeed for the very useful post. Most thoughtful.

UPDATED to include official specs!

i have a question ... on the last picture you are pointing out to #6 73ft-lb ...
isn't it suppose to be #7 ?

aren't they the same? it's a bolt with a nut. you can tighten either one.

Nice, rzm3 ... now you can update your original post with the top nut torque specs.

Great thread....now we need ALIGNMENT SPECS!

Does anyone know what torque to tighten the front strut hat nuts (the ones that hold the front strut to the strut tower)?

OK, I’m a bit confused here. In the second diagram it shows “64 Nm or 47 ft-lb” pointing to the top of the strut assembly, yet it looks like the next diagram shows 37 Nm or 27 ft-lb pointing to the nut which goes on top of the shock. What does the “64 Nm or 47 ft-lb” actually refer to? Is that shaft of the EDC shock supposed to be tightened? I thought the shaft just spins in place and the bolt (37 Nm or 27 ft-lb) on top of the strut is what you are actually worried about tightening.

This might be obvious, but I need some direction here

first shock diagram is the front, second shock diagram is the rear

Yes, I know which is front and rear. So the bolt on the top of the front strut is 47 ft-lb then?

I guess I was confused by those last couple of posts
