So my buddy is selling his eibach spring lowering kit for 150$. Only thing is he has a g37 coupe. Will it fit my 04 g35 sedan?

 

Nope

 

If I never track my car, would it not make sense to get softer spring rates on stance coilover for comfort? I was thinking 9k front 6k rear on around a 2.5" drop on a sedan.

 

Do you guys think the motordyne plenum spacer is worth it??

 

^ Depends on how you classify "worth"

 

Like can you feel the improvement in the car?

 

Depends on how sensitive your butt dyno is. The plenum spacer is a good mod for the money.

 

Sounds good. Easy to install??

 

4/10 on ease of install with 1 being easiest. Reason being? You need access to an inch pound torque wrench. So many people break plenum using ft lbs :facepalm:

 

you don't reeeeaaally need an in-lb torque wrench... just need to not be an idiot.

 

You can rent one from autozone for free. They even give you the tax back and you can take the tool home.

 

Okay cool thanks

 

Yea, that ^. You just need a bit of German torque, but not too much. Hand torque to just where it starts to tighten enough to where you need to start applying any real amount of muscle to turn it, then give it a quarter turn and you are done.

 

MD even says that in their instructions that if you don't have an in-lb torque wrench then you just tighten it by hand. smh at anyone who actually fvcked up their car using a ft-lb wrench.

 

It's not so much about breaking the plenum with a hand wrench, it's more along the lines that you need to tighten your plenum correctly to prevent air leaks or warping over the years.
