Z1 370Z / G37 / '07-'08 G35 Sedan Aluminum Subframe Bushing Collars

starstarstarstarstar_half 4.8/5 - (55 Reviews)
Fits models: 370Z / G35 / G37 / Q60 2014-2016 / FX35 / FX4...

Product Description

The subframe on your 370Z / G37 is designed to blend comfort with performance, using soft rubber bushings on all four mounting positions. These bushings work well for a car driven in a stock environment, but when your car is subject to the harsh power transfer that takes place in drifting, circuit, or drag racing they leave a bit to be desired. Solid subframe bushings are available, but changing these is no easy feat and requires that the subframe is completely removed and factory bushings are cut out, and the comprimises they bring make them less than ideal for most street or dual use cars. This is an expensive and time consuming repair.

Keeping these challenges in mind the Z1 R&D team put their minds to work and began developing a simple and cost effective, yet easy to install solution. 

Why is subframe rigiditiy important?

Maintaining subframe rigidity in relation to the chassis helps maintain suspension geometry when under suspension load or drivetrain torque, helping reduce harsh and harmful wheel hop. Z1 Subframe Bushing Collars take up slop developed by old stock rubber subframe bushings, to yield a more responsive and direct suspension while reducing wheel hop on aggressive launches.

These 8 piece aluminum collars install above and below each of the four bushings and retain the stock anti-squat geometry. Installation can be completed in your driveway without any special tools, making this the most cost effective solution. Because OEM rubber bushings are retained this offers minimal compromise in driving comfort and NVH.

Features:

  • Vehicle Specific Design
  • Greatly Improves Drivability With More Predictive & Surefooted Response 
  • CNC Machined From Billet Aluminum
  • Black Anodized Finish With Laser Etched Logo
  • Better Value When Compared With Other Subframe Bushings
  • Engineered and Tested IN HOUSE On Various Platforms

Fits:

  • 2009+ Nissan 370Z
  • 2007-2008 Infiniti G35 Sedan 
  • 2009-2013 Infiniti G37 Sedan
  • 2008-2013 Infiniti G37 Coupe
  • 2014-2015 Infiniti Q60 Coupe

NOTE: These collars do not fit the G37 Convertible models!

For the greatest effect, use these on cars with Solid Differential Bushings!

Not as bad of an install as I thought it would be. I actually think the ride is better and things feel tighter and more able to put the power down to the pavement. I recommend doing the exhaust and rear sway bar at the same time.

I knew these were going to help but I had no idea the difference would be so dramatic. It’s night and day, the rear end is so much more responsive. Install really isn’t bad at all either.

This Product is definitely a great way to fix the horrible banging/jolting in the rear end when Launching and or doing a burnout in a Z car. Before install of this product when you would dump the clutch it felt like the subframe was Going to fall right out from underneath of the car. So I purchased the Solid Z1 differential bushing set and that Solved a lot of the issues I was feeling but I still felt Like the car had violent results when pushing it to its limits. I have done solid Bushing swaps before and considering the time and effort you have to go through to install Solid Subframe bushings, these Subframe Collars definitely come almost identically close to the same result. Im beyond happy with the outcome and I can finally break the tires loose in my Z without the feeling of breaking things. The install was way easier than a full Solid bushing swap but I HIGHLY encourage anyone who is not skilled/fully trained enough to drop a subframe, to please not take on this job alone. But definitely a 10/10 Must have modification for anyone that does more than just daily drive their car.

Don’t think I could get rear upper in proper. Wish instructions would say how to put the top in rotated to the bottom one. Now its going to the shop cuz it feels off at hi speed installed diff brace at the same time get bad gear noise at 6000-7500. After i get it back from the shop if gear noise is still there brace will be comming off.not happy so far with sub frame collars might be just getting the bushings replaced and doing it properly.

Well made and the fit and finish are perfect. I use this on my 2009 FX 35 it stiffing it nice and snug what they are made for. Pros: Easy to install Cons: *Please note this is no fault of the part this is my own opinion. These Collars stiffen up the rear end way too much you feel everything. These are not for your everyday car, I try these because I had a lot of play.

These were a pain to install. The large collars did not want to seat in the subframe at all. Once installed though, along with the poly rear diff bushing / diff brace felt really good. I also have the z1 engine and trans mounts. They all work well together. Car felt really smooth, no jerkyness between shifts

As an owner of a 2013 infiniti g37x I own the heaviest version of the g. The rear end to the front end felt seperated. I bought these thinking they won't make much of a difference but it definitely tightened the rear end. And gives you more control and road feel. I also did put on the rear diff brace from z1 which also showed an improvement in power to the floor.

Feeling is night and day with these collars with increased handling, stiffness, and feel for traction. DO NOT be an idiot and completely unfasten the rear two subframe/suspension stay nuts without supporting it with a jack first or you'll be committing blood, sweat, and tears to realign the frame studs into the back subframe bushings. The back half of the subframe will sag if you mess this up and has the potential to snap the studs. Take it slow with plenty of support and remove the remaining hardware to level out the subframe and realign with the rear studs. Loosening the main 4 subframe fasteners progressively is highly recommended to keep it guided with its mounting points as you achieve the clearance to install the inserts. Prior to the 4 main fasteners, support brackets need to be removed from each side at the frontal corners of the subframe.

Make the car feel much more rigid and stout. You won't feel the chassis flex over rough roads as much or getting on or off throttle. Overall make everything just feel more solid and super easy install. Especially if you have access to a lift. Killer upgrade when paired with the diff upgrade kit and brace.

Once again the delivery time from USA to Perth Western Australia was just over a week which is alot better than the mail time in my own country. This product is very nicely made and I can't wait to get them installed on my 2015 Nissan 370Z Z34 Sports and you would be crazy not to buy this product as it will make your Z even better. Again out standing work Z1 Motorsports it's one more performance part crossed off my upgrade list. Buy this product boys and girls it's worth the $$.

Thank you Z1 for making these! If you have access to a lift, power tools, and know how to loosen the subframe mounts some then these can be installed in 30 mins to an hour time. Mise well install these if you need upgraded diff bushings too. Definitely tightens up the back end!

I was eager to get these on after reading about them. The installation took a bit longer than I thought but that's more due to the state of my car's undercarriage than the actual collars themselves. Do yourself a favor and drop the exhaust hangers and loosen the slip joints so that the pipes can be moved/turned. This made things very easy. These have a great build quality and fit perfectly once they were lubed up a bit. Once the car was back on the road I could feel that the rear end was tighter and wheel hop was lower with no noticeable increase with NVH.

These sub frame collars add much needed stability in the rear end with out a bunch of vibration or noise. When power is applied it is much more engaging and solid. The install was pretty easy and took about an hour. These added with the diff bushing kit make the car handle and shift much better then before.

February 18, 2018
significantly reduced rear end walking/torsion during hard acceleration and hard gear changes, I can see these promoting more consistent tire wear also. subframe has to come down quite a bit for the forward collars so I recommend an alignment after but the subframe has pretty beefy centering studs so it's really just if you have easy access to an alignment rack I guess. I did these the same time I did the differential bushings to make everything easier. They weren't hard to do with a 2 post but, no, I wouldn't attempt any subframe work if you aren't an experienced mechanic. Strongly recommended

I hope more folks get these collars because they are worthy of a BUY NOW purchase. I did it in my driveway without beer or power tools. The bottom collars do need lubrication and some man power to get it up (pause). I didn't have a rubber MALLET or sledge hammer available so I used the subframe to be finish the job. The top collars legit just fall in place. that first drive you'll be like Holy nosubframe flex! there's really no movement back there. It's all the positivity of a solid bushing without the negative NVH they bring.don't just browse the product. BUY IT!!! PS. #FMY

Installed these on the weekend and they are one of the easiest installs I have done, even without a hoist job was done in less than an hour. good squirt of WD40 allowed then to slide in a little easier. Instant change in the cars response on and off power. One forst look they are a great bang for your buck mod.

Very good quality, as the video shows they are easy to install even with basic hand tools. I suggest you lightly grease them so they slide in easier. Feed back from the car is improved while driving in a good way. Best mod under $150 by far.
