Kuah isnt busy on these....hes waiting, like i said before, he has no idea when they will be ready.....which from our email contact he said he is waiting for the 1 inch bearing.....im guessing hes ordered a bunch from china or some place and waiting for them alll to come in......

I figured I would ask since you posted that "you" made those and they dont exactly look like what Kuah showed me (in person in austin) and wanted to see if you might be able to make another or more...

Seems you work with kuah often and don't seem comfortable answered my questions instead of just simply answering it the first time....ya if its a one off you made with tons of machining then ill just have the machine shop i work with often work at making some unless kuah can come around with his product soon.....

I don't see where we ever left talking about it.......

What I am waiting on is the custom 1" Endura type bearing with the slot-loaded injection molded liner. This bearing is suitable for street use because the liner cannot pound out. No one in the world right now offers a 1" Endura bearing, we have to wait for the bearing manufacturer to tool up to manufacture this custom bearing for us.

If you want the compression rod bushing with a regular 1" teflon-lined bearing, I can make it happen within 1 week. With this type of bearing, the liner can "pound" out if dirt gets caught on the bearing. That was the prototype you saw at the shop, and this is the same type of bearing Sasha is using. Its not an issue for a race cars, since it is part of regular maintenance to inspect and clean the bearings.

 

pm me price for teflon-lined bearing please? I don't street drive my car at all.....its soley track, but NOT a race car as the level of Sasha car.....so either way i can monitor/clean, etc....

and

also pm me price for when you get the new one in (1" Endura type bearing)?? still no word on time frame?? I may wait if time frame is within reason...

I have gone through many compression rods.......im on my last set i have acquired...

Hey Jason,

As a moderator I would think you would keep your emotions in check a little bit more, we're all doing our best here to help the community and supply products as fast as possible, Kuah is a great guy and possibly one of the most stand up people in the industry. Who else offers upgrades for newer suspension arms at or below their own cost?

I don't mean to be rude, but your posts came off a little bit abrasive, that's all.

You have to remember the demand on these kinds of products is nearly zilch, so putting a ton of time and money into certain products sometimes just doesn't make sense unfortunately

 

as a member and moderator i asked a few times, no clear answer was given till the last one... i guess i get fussy with a bushing i have delt with multiple times and wanting a replacement........

emotions aren't breaking rules......so as a moderator all post have been acceptable............im sure any moderator would agree....

I too have talked with multiple machine shops, etc been given quotes left and right all over the U.S. its expensive making a "one off" .......please, i think you feel my pain...

I in no way mean to degrade your being here or kauhs.......im just wanting a bushing!.....lol..


sorry, like i stated above.......i hate that bushing...

I agree, all my buds that tear this bushing just roll around with crappy caster and dont care...........

I have been looking for a replacement for quite some time.........I have gone through multiple compression arms i have acquired.....mostly from junk yards, one at a time compression arms with good bushings just to buy me 4 months time.......

One side 50 bucks type deals, since the cars they were pulled from where frontal impacts on one say the drivers side, so ill take home the passenger side, then I will scour more junk yards for a driver side......etc...

To me, im glad kauh posted, cause to me its most likely gonna be worth it to buy a teflon lined bearing and then later replace with the Endura type bearing when it comes out........etc..

Sorry for my curt reply, I was a little fustrated... The bushings are $167/set, it is the same price for the regular teflon-lined bearing and the endura bearing.

The endura bearings were supposed to be completed end of March, but the manufacturer didn't make that delivery date. However, it should not be too much longer, my best guess is that it would be another month.

 

I am wondering that as well..........

For drifting, we tear the compression rod bushing all the time when at full lock........along with inner wheel rim contact and rubbing/wearing a notch into the compression arm itself...

The stock bushing obviously has some forgiveness....then eventually tears...Im curious of this with the solid compression rod bushing.... and i dont wanna run a small wheel up front....

Haven't heard anything yet, and I'm only running on R-Compounds with modest downforce. Once I get an underbody on there and start running Advan and Dunlop slicks perhaps we'll run into an issue. I sure hope not though!

Nissan designed this stuff to have a pretty big safety margin for hitting curbs and bumping into things which can have pretty high shock loads. As long as I don't hit anything at speed I believe I will be ok. Of course if I didn't believe I would be ok I wouldn't be able to drive the car near as fast as it can go, which would be a sin.

 

I am curious how much compession travel you are getting in the front. After I installed SPL's front compression rod bearing and ran the suspension up, I found they run out of travel before anything else.
My ride height looks similar to yours and I am getting about 1.7" of bump, not even close to the stops on the coilovers.

We have cycled both the front and rear suspension through its range of motion and there is no bind with the solid spherical bearing bushings (except at its mechanical limit, as discussed below).

Just an update to this post, I have been conversing with Christian by email over the last few days.

When I designed our compression rod bushings, I checked the bump travel on the bushings to be about equal to the maximum travel possible with the a-arms, which is when the a-arm almost contacts the fender and the knuckle, which is also when the tire contacts the fender. This is the mechanical limit to the multilink and tire/fender. Christian confirmed this after cycling through his suspension again.

Neither the compression rod bushing and the a-arms are designed to be mechanically bottomed out. It is important to control the bump travel available through spring rate and bump rubbers. This is one of the things that is often not setup or checked, though it is often not an issue on most cars. But on the 350Z/G35, due to the motion ratio on the shock, the coilover/shock usually has a lot more bump travel than is physically possible on the multilink.

If you lower your car, you are reducing the amount of bump travel you have, because the limitation is what is physically possible on the tire/fender and the multilink. So then the important thing is to control the amount of bump travel available through spring rate and bump rubbers so you are not bottoming out the suspension. For example, if you started with 4" of bump travel, but lowered the car so you end up with only 2" of bump travel, you would need to double your spring rate so as not to be bottoming out the multilink, if everything else is held equal.

An old trick to check the amount of bump travel you are using, is to place a zip tie around the shock piston at the bottom, then checking how far up the zip tie moves on the shock after driving. If you find the position of the zip tie corresponds to where the multilink bottoms out, you need to increase the spring rate and/or add bump rubbers.

 

Hi I notice you have the rear subframe bush installed as per the spl instructions
I had to instead install some supplied shims sing could get proper thread engagement

The instructions state to not use an upper shim on the rear of the subframe if you want to retain oem set up

It looks like you were supplied a spacer for the bottom of the subframe Which is maybe why the bracket is spaced out underneath in your picture ?
If so did spl supply ?

Compare mine with yours
