* New Product Debut * 4th gen Subframe Collars
Want better handling and more precise steering?
Want a smoother ride with that stiff suspension and big wheels?
Want to reduce wheel hop?
Then you need this subframe reinforcement kit!
First of all, I’m pleased to announce that I am now a Sponsor of the forums after all these years on maxima.org!
This first product release is something that has been tested and developed for a while. It is an 8 piece set of front subframe reinforcement collars. The subframe on the Maxima has long been ignored, but is critical in properly transmitting power to the tires as well as locating the suspension components to maintain alignment geometry.
These precision machined collars remove the slack from the mounting points of the subframe, allowing the suspension to absorb road bumps more effectively and the drivetrain to smoothly put the power down as it will now be better tied in to the actual chassis of your Maxima. The squishy mounts were barely adequate on the stock car when new, and with age and upgrades to the car, this reinforcement is a must.
Installation of this kit it fairly simple and can be done in under 1 hour by those with a basic automotive tool set. The kit includes a diagram and complete instructions to make this a DIY project.
To give you an idea of where these pieces go, here’s a diagram of the 4g front subframe:
As can be seen, the suspension, engine/trans, and steering all mount to the subframe! You can imagine that it’s not something you want to have moving around, especially if you’ve already gone through the trouble of upgrading all control arm and motor mount bushings!
As an introductory sale, this kit is available immediately for only $89 shipped! You can submit payment through paypal to idsi.corp@gmail.com . Please include year of the car and use a confirmed paypal shipping address as we can only ship to your confirmed paypal shipping address.

Hey guys,
they are made our of Delrin so they are tougher and stronger than stock but will not transmit as much hardness and vibration as would the commonly used aluminum subframe collars.
I'll check on shipping for you, to Canada it probably will jump about $12 for Priority International shipping.
thanks guys!

I have one of the first sets on my car and it make a big difference. The ride got a lots smoother going over rough roads, and the steering is more direct now. It feels like i riding on the stock 16's but with the tightness of a BMW.
They installed it for me and it was done in about 45 minutes.
Thanks carnal!

yes they definitely will help any Maxima auto or manual, we all have loose subframes after all these years

The collars will come with a print out and instructions of where they go and how to install them, its quite easy, about 45 minutes and you're done!
The picture from the FSM posted shows the front subframe and the collars go where the subframe bolts up to the rest of the chassis, you can do it at home in your garage you just do one side at a time and slim them in.

This is something nobody makes before. The energy bushes are for the engine crossmember, that attaches to this subframe. I thought my car was good after every single ES bush was install, but with this kit it feel like new control arm and motor mount bushing again. Hard to explain the feeling, but less harshness is transmitted to the driver.

I sent payment this morning and I just got 3 paypal messages. The 1st said my package was shipped, then the 2nd said shipping was cancelled b/c the package was destroyed, then 2 min later it said package was shipped. What's going on?

Edit: Got your pm, thanks! Look forward to trying these out!

Well since the cat is out of the bag and i won't likely have time to do any reviewing till maybe Sunday...
I was one of the test subjects for these on the 5th gens. So I'll toss in my .02 cents.
A little background: the subframe on a Maxima is held in place by several bolts threaded through bushings that are pressed into the subframe. These bushings are in place to minimize engine vibration and road noise being transmitted into the cabin of the car making it quieter. Over time these bushings tend to break down due to heat, age and use. Once they do break down they tend to cause sloppy handling, sloppy steering response and allow your engine/transmission to slap around when you are accelerating/decelerating. Many Maxima enthusiasts that invest into their cars spend $1000s on suspension-tightening springs, struts, tie-bars sway bars etc. without considering that 1000Lb (I'm guessing here) mass slapping around by it's connecting points.
What these do: In essence they eliminate the movement of the subframe without making it completely solid. Why not just make it solid? Because engine vibration will crack steel and will certainly make our cars too harsh for everyday use. Think about it this way, a go-kart is a fun little vehicle, quick, maneuverable but nothing you will want to commute to work in. These collars while making your subframe stiffer will still absorb much of the vibration from the engine and continue to isolate a majority of the roadnoise that transmits through your axles and into your drivetrain.
My review: For the price you won't find a suspension mod that makes this much difference in the way your car feels. Steering is much tighter, accel/decel becomes very crisp even if you have the stock motor/tranny mounts and the front end of your car will feel so much more solid. The only drawback if you consider it a drawback is you will hear more engine and road noise inside the cab but it's minimal, nothing another click up on the volume **** on the stereo won't overcome. Another element to these is they do force your struts and A-arms to, well you know be parts of the suspension and absorb bumps in the road. So, minor road imperfections like rocks and drunk bumps won't be as jarring to your car.

If there is an increase in road noise I am thinking to fill that subframe crossmember with chassis foam. I've seen it done on some cars to stiffen the subframe and reduce noise/vibration from aftermarket suspensions.
It would involve alot of work removing the front suspension so I really don't want to do it. However my car is due for a front suspension overhaul so it won't be much more work than I have already planned.

Not necessarily, basically you are removing the subframe bolts, slipping in the horsecollars, threading the bolts through the washers and tightening everything else back up. Andy, the designer of these roughly spent an hour installing them with nothing more than a floor jack, an impact gun and hand tools. And that included re-machining some parts.
These inserts should take me less than an hour to do.

This is very interesting, now is this something that will be felt day and night difference? Like once they are on and i start driving I will definitely feel it right away? or is it something I have to really concentrate and see if i notice it and then determine if its in my head what im feeling or if I am really feeling it?
