^^Nice hold down

 

Made it nice n easy,

 

^^So total weight saving ~#100 give or take. Can you actually notice that in driveability? The car is what, #3700 or #3800 overall. I can see things like the flywheel making a difference as you're directly connected to it via right foot, wheels maybe?

Have you done anything to the rear end? I bet shorter gears would make a pronounced difference.

 

I believe the 6MT sedan is one of the lightest models and I think it weighs in the 3,600's stock. I definitely felt a difference with the lighter wheels, and now with all of the combined weight savings so far, it does feel less shifty overall. I do plan to get z1's new 4.09 final drive too It's on the list! I may try to do it all at the same time - clutch, flywheel, 4.09's, diff brace. But the brakes come first, they're in really bad shape right now. And I just ordered an FI exhaust in February.

 

I heard great things about the anti gravity battery, it's a bit pricey but a cool upgrade nevertheless.

 

Curb weight on the 2013 6MT Sedan is 3709 pounds.

Nice thank you for the correction! So my car would end up in the low-to-mid 3500's when all is said and done. I'm pretty happy about that for the class the car is in.

 

Does anyone know where someone can get g37x09 sedan aftermarket parts at?
like a simple catback?
i can't find a single aftermarket part period.

 

Have you tried google? There are literally hundreds of parts available.....?

 

I tried to put clamps on my pcv hoses and couplers but I discovered this:


Also 63-71mm clamps didn't fit on my couplers so I have to return them and order 70-80mm clamps.

 

Tried to suggest this at the part that is relevant but they said the bushing isn't stiff enough and put in a stiffer one. Then they bent the exhaust with a bar. It seemed like it was fixed, and as you can see it's further from the sway bar now:





But after I got home I heard more rattling .

So I was moving the mufflers/tips around and I added some cut up plastic cards in that spot you circled as an example. It seemed to lessen it and I started noticing sound on the right side too so I added more to the left and added some to the right. I didn't have a lot of time to check because of work but I think the issue is resolved. I wouldn't mind a neater solution but I don't think the cards will fall out or get too hot based on the location and it's hard to even see these unless you're looking for it so it will probably be fine long-term.

Below is an image before I added a little more:

 

Alright, here's a cold start and rev with the new exhaust setup. I will provide more videos after retune.

I wish you wouldn't C&P your comments into multiple threads.

 

One is a build thread and one is a mega thread and both serve similar purposes.. I can re-word things slightly for you, I guess?

 

I have joined the club, just waiting on a good day to install.... Front and rear 2-piece and Centric Posi-Quiets to go with them.
