Aight

So I am going to start fabricating some chassis rigidity bars. Looking for input on what you guys would like to see, also any sort of end goal (front end, rear, total, etc..)

What I have planned:

4 point front strut bar: ties the two struts with a regular cross member, but extends to the rad supports, stillen makes something similar and it felt great in the z and another fabricated one felt phenomenal in the CTS. I am not sure why the front rad supports tied everything up so well but the damn front end felt like steel when turning, zero flex almost like sways... Mine will be titanium but planning on some steel and aluminum mock ups...

Rear lateral brace, made to clear big pipe exhausts, need some megan axle backs to double check, and some fatass resonators, but could prolly eyeball it

Front Lateral brace

Chassis mid brace, looks like i have all the mounting points in the world under their, only issue is clearance with dropped rides.

Diff brace of course

Cold rolled sways

torque dampers

Some sort of transmission supports, idk just yet, there is a ton of flex under there, and this would make acceleration so much more fluid all the while preserving oem longevity... still brain storming on that one.

Any more ideas??? These should/could be universal fit for most M chassis, once I get into bushing/mount work, we can seriously make the car an extension of the driver...

______

I know some of yall are scratching your heads as this is not a track car, rather a luxury sedan. BUT, once the vehicle is tied in with rigid supports the car seriously rides better... I swear to god just the rear lateral brace makes cut springs feel like monster shocks... spose we'll see.

cheers :dblthumb:

Yeah man, the car is a beast... Have to get a damn steel jack cuz the alum one is stressin rofl. Luckly, these braces for the most part will be aluminum. I'd reckon a total of 10-15lbs for literally every brace I mentioned.

Also... all the body flex is made worse by the weight and odd proportions of the M (as it sits on susp) so these braces can in theory distribute the dynamic weight much more effectively. It will feel lighter at least...

Are you the only one interested in my M?? ROFL...

So are you going to be selling these if people want them then? Or just for your personal stuff?

Ten years ago I had an SHO with subframe connectors welded in and it made an amazing difference. So much so that my wife would leap on an opportunity to have something similar on her M35x today.

Honestly it is for my personal enjoyment. I might be willing to put some time aside to make a set, but would have to be a group buy. Also would like to test them b4 selling... wouldnt want some weird s*** that I didnt think about pop up and everyone hate/sue me...

I'm sure a rear lateral bar somehow makes the infiniti reverse its harmonization causing the turn signal fluid to damage the cpu harness's pressed valve gasket...

:ohno:

Least thats something the dealership would say... FFS I seriously thought Nissan mechs and dealers were bad, HOLY SHIZ! Infiniti are some price marking mofo's and know crap about their own vehicles, save an oil change or alignment.

But yeah, if there is like 5 dudes that wanna try it out with me, we'll figure something out, maybe a beta test or sumtin... (will def have to confer with my comrade fabricator tho, technically his shop :naughty: )

I know man, its crazy how much the dynamics of the vehicle change. This one wave of mods is one I always look forward to doing, it, nothing else, is the most bang for buck on any mod imho.
