Recently put on 19" Hyper Silver OEM G37s Coupe rims and just lowered the car on Eibach Pro-Kit's 2 days ago! Enjoy!

 

Looks nice

 

Very sexy. Love the stance and wheel combo. I would have loved to find coupe rims when I was still on eibachs. Could have made the difference to keep me from switching back to factory springs! Nice to see another well cared for blue slate.

 

Nice, classy, and clean~well done!

 

Looks great- I do love the coupe wheels on a sedan.

 

Beautiful, elegant, fascinating.
words are not enough to describe my emotions...

how does it feel?

 

Looks great! What are the tire sizes? They look almost flush. Do you have pics relative to the fenders?

 

looks good

 

Dang this looks good. Can't wait to toss my coupe 19s on

 

Thanks for the kind words! It feels GREAT! Handling is noticeably improved. I'm very very happy I did this.

Next up are these few upgrades (in no particular order):

1. Hotchkis Sway Bars Front/Back
2. MXP Exhaust (doesn't seem to have Sedan exhaust on MXP website, but I've definitely seen it done before. Can someone shed some light on why they don't have the sedan exhaust on their website?)
3. R2C CAI
4. Some kind of HFC. Can someone tell me: do aftermarket HFC's replace the stock catalytic converter on G37 Sedan's?
5. Paddle Shifter Kit!

...and also, I have 225 in the front, and 245 in the back. I might put 10mm spacers all around! Thoughts?
Thanks!

 

Yes - all aftermarket HFCs will replace the stock cats you have in your G37. Seems like the most popular options are Berk, Fast Intentions and ARK. There are a few more options out there that you can select from, as well as a whole list of test pipes if you wanted to eliminate the catalytic converter all together.

As for the spacer question, I know 20mm will get you flush at all four corners, so a 10mm will get you almost flush from what I've gathered. Either options will look great regardless - just depens on how much you want to space your wheels.

 

Thanks, I'm relatively new to the whole car modding scene. Will I still pass emissions, how does that work? Does an aftermarket HFC increase loudness of the exhaust note (on a stock exhaust?)

Thanks for the help!

 

OP - also add front chin and trunk lip to your list, the OEM ones. would complete your classy look nicely.

big props for making sways your next mod. very wise. you'll be blown away with the handling improvement.

i've been going back and forth on adding my front splash guards, so far i've just added the rears. yours is the first BS sedan i've seen with both for comparison which gives me more to think on.

oh, don't forget to get your alignment checked after a couple weeks on the new springs.

 

I have seen it before, but I think it only comes in stainless steel for the sedan.
Not sure why not on site.

I have no issues with the Fast Intentions resonated HFCs. No problems with emission in Virginia (VA has very strict emissions laws) and no weird issues with check engine lights. The Fast Intention pipes have an extended bung to help "fowl" the readings.

I currently have these installed with my stock exhaust and I noticed a slightly deeper tone, but not louder. When adding a cat back exhaust, the loudness will increase depending on which system you go with, and whether or not that system has resonators or not.
