Front Subframe Bushings

[Draxus]

*UPDATE*

034 Motorsport made them for us!

They are available here: http://www.034motorsport.com/chassis...i-p-21362.html

Hey guys. This just popped into my head when I was helping my friend with his S4.

What you think of this comparison. The front bushings on a S4 look very much like the R32/Golf bushings. I am going to contact them on Monday. Anyone know the size of the front bushings or have access to some to pull some widths?

Thanks guys.

in for info - looks intriguing.

In as well. I'm compiling a list of suspension bushings and components. Found out my control arm bushings are starting to tear and squeak, just going to budget out a complete suspension overhaul.

I remember when these were introduced over @ Audizine. Lots of positive response.

I'm curious about this. A few questions for those who have seen them.

1. There doesn't seem to be any flexible material or spherical bearing. Is this correct?
2. Does this effectively mean the subframe is fixed to the chassis?
3. On the web link they speak about clearancing the bushing to the subframe. This would mean there would be no play between two hard surfaces.
4. I understand minimizing the movement from subframe to chassis, but no movement?

interesting

Anybody have a part # for these? Mine are shot.

[Draxus]

Ok. So I talked to them. They have no idea if it will work or not. Does anyone have a bushing sitting around? This is going to take a test fit.

And yes, it would be effectively locking the subframe down. No movement. It's a good thing.

Probably at the sake of your roof line, but it sure would feel good in your hands.

[M00NEY]

Grant, do you think that much stress would transfer to the roof line?

and I will look when I get home - I may have a set of bushings...

[R32Freddie]

Watching.

[huichox4]

seems like a good idea. hopefully the use of this dont cause alignment issues, the subframe with stock bushings can be shifted a little to be able to get the car to align.

I will definitelly be interested if this works nicely.

[xbluewaterx]

I have a spare new subframe sitting at the shop. I will take some measurements.

[Alexi_from_finland]

Nice photo. I have those both on golf and R32. Golf is new and R32 bushing old. BTW seat leon cupra and audi tt uses same as R32

[Alexi_from_finland]

And those are CM

[xbluewaterx]

So the diameter of the subframe hole that the bushing goes into is exactly 66.50mm or 2.618"

I am not sure. I know that sometimes, when I catch a reflection just right, I think I have lines running from door to door. I especially have noticed on the outer edges. All I have is lower tie bar brace, coils and stiffer rear sway. Maybe just my mind though. After all, it is just a roof....

I am intrigued to say the least though. I want solid shock mounts first.

Strut mounts? Working on it..... :hide:

[Draxus]

Thanks for the pics and info guys. I am going to call 034 again on Monday. They were very receptive to the idea and the bushings are made in-house. So we might be able to get something made none the less. lol

Any news?

[Draxus]

Sorry guys. Midterm took all my time so I was not able to make the call Monday or today. Wednesday for sure.

[vwfansince95]

great thread & info ..

watching as well

[Draxus]

Email sent. Awaiting reply from 034.

[M00NEY]

<-- patiently looking forward!

My question is would you need to run solid engine mounts with these subframe mounts i this works out? My BMW racing buddies have always told me not to mix and match your bushing material. I am looking forward to your email reply Draxus.

Added question: Anyone know the size of the rear subframe bushings? Would these fit as well?

[MatadoR32]

I don't see why you'd have to run solid engine mounts. By that logic just by running the VF engine mounts you'd have to switch over your entire suspension bushing set soup to nuts. Perhaps they meant like don't mix poly with OEM rubber on your suspension directly?

[Draxus]

YES!

Spencer,

I want to make sure which sub-frame you are looking at. I believe we were discussing the front sub-frame. If this is the case, we should have something ready for you in 3 - 4 weeks time. I will e-mail you with more specifics as time moves on. Let me know if you have any questions. Thank you.

034Motorsport

I responded to confirm front.

Now, someone get me the dims for the rear!

[huichox4]

I need solid mounts for my carrrr ........ everything ............. subframe, front and rear, engine and suspension.

it still bothers me when it moves and potentially things get kinked or touch specially when so much is going on in the engine bay and subframe area with the exhaust hanging very close to the driveshaft.

[R32Freddie]

YES!

Hells yes!!!!!

[M00NEY]

me too. Hells yes!!!!!

No, it is just related to engine and tranny mounts, not suspension. The engine and tranny (dogbone for us) are all connected together by the same forces. You wouldn't want to run a solid mount on your engine and run poly on the tranny. That poly is going to get torn up really fast since it wants to move and the engine does not. After talking with my BMW friends I don't think it would matter for us if the subframe was solid and engine/tranny being poly or what ever you wanted.

Agreed... It really depends on the specific combination of bushings... like in a typical front engine rwd Longitudinal drivetrain you don't want to put a solid transmission mount in when you have soft engine mounts because you can damage the mount on the transmission when the engine is still trying to move around. The way the bushings are set up on our cars I don't think you have any similar bushing arrangements to be concerned about.

[Draxus]

It's all about the individual systems. The subframe, A-Arms, etc are part of one system. The motor and trany are another.

So the next thing we should look at are spherical bearings for the A-Arms.

[MatadoR32]

BAMP!
