[034Motorsport]

Introductory Special: ENDED

We're pleased to announce an exclusive Introductory Special on a line of all-new B8/B8.5 Audi A4 Drivetrain & Chassis Upgrades by 034Motorsport! These performance parts are in-stock and ready to ship.

034Motorsport Drivetrain Mount Insert Package, B8 Audi A4/S4/RS4, A5/S5/RS5, Q5/SQ5 Billet Aluminum

Retail: $255.00 + Shipping

Introductory Special: $225.00 + Shipping

(Individual inserts are available separately below.)

Introductory special pricing is available through June 20th. Thank you for all of the interest, and we hope you enjoy this new line of performance upgrades for your Audi!

034Motorsport is proud to offer our Billet Aluminum Drivetrain Mount Insert Package for the B8 Audi A4/S4/RS4, A5/S5/RS5, and Q5/SQ5! The factory Audi transmission and rear differential mounts have large voids in the rubber damping medium, which results in excessive drivetrain movement under load. This movement results in slop than can be observed when accelerating, decelerating, shifting, and launching.

These billet aluminum inserts are designed to fill the large voids in the factory transmission and rear differential mounts, and limit drivetrain movement without sacrificing ride quality or introducing any additional noise, vibration, or harshness into the cabin. By filling the voids in the factory mounts, this package eliminates the associated slop to ensure that you experience crisper shifts, harder launches, and a smoother driving experience.

This mount insert package was thoroughly tested by 034Motorsport, JH Motorsports, and independent Audi enthusiasts before release. Installation is very simple, can be performed in minutes, and is completely reversible.

Features:

• T6-6061 Billet Aluminum Construction
• CNC-Machined In-House
• Clear Anodized Finish for Durability
• Engineered to Fill Voids In Factory Transmission/Differential Mounts
• Drastically Reduces Transmission & Differential Movement During Shifting & Deceleration
• Improves Shifting Feel, Resulting in Crisper Shifts
• Allows for Harder Launches & Better Response from Rear Differential
• Will Not Cause Additional NVH Transfer Inside Cabin
• Easy, Straightforward Installation Takes Minutes!

What's Included:

• 034Motorsport Billet Aluminum Transmission Mount Insert

034Motorsport X-Brace Billet Aluminum Chassis Reinforcement, B8 Audi A4/S4/RS4, A5/S5/RS5, Q5/SQ5

Retail: $495.00 + Shipping

Introductory Special: $445.00 + Shipping

034Motorsport is proud to offer our Billet Aluminum X-Brace Chassis Reinforcement Upgrade for the B8 & B8.5 Audi A4/S4/RS4, A5/S5/RS5, and Q5/SQ5! The factory Audi front subframe brace is manufactured from multiple pieces of stamped steel, and allows for performance-hindering chassis flex under load. This torsional flex can result in improper suspension geometry and alignment when cornering, and leads to vague steering feel and lack of steering precision.

The 034Motorsport X-Brace is a billet aluminum chassis reinforcement to replace the factory front subframe brace to increase torsional rigidity, resulting in improved steering feel and handling performance. Machined in-house from T6-6061 billet aluminum, the 034Motorsport X-Brace is engineered to outperform the stock welded, stamped steel part and ensure that suspension geometry is not compromised by chassis flex under hard cornering.

This chassis brace upgrade was thoroughly tested by 034Motorsport and independent Audi enthusiasts before release. Installation is very simple, can be performed in minutes, and is completely reversible.

Features:

• T6-6061 Billet Aluminum Construction
• CNC-Machined In-House
• Clear Anodized Finish for Durability
• Engineered to Replace Factory Front Subframe Brace
• Drastically Reduces Chassis Flex When Cornering
• Enhances Handling Dynamics and Performance
• Improves Steering Feel, Consistency, and Precision
• Will Not Cause Additional NVH Transfer Inside Cabin
• Modular Design Fits Both B8 (Pre-Facelift) & B8.5 (Facelift) Models
• Easy, Straightforward Installation!

What's Included:

• 034Motorsport Billet Aluminum X-Brace Chassis Reinforcement (Fits B8/B8.5 Audi A4/S4/RS4, A5/S5/RS5, Q5/SQ5)

No email no order...
Who am I kidding order placed, should have waited for them all to be released before I went apikol though...

[djspecv]

Just ordered the rear diff carrier mount. Already had the apikol rear diff mount insert, EC alu kreuz and 034 tranny mount.

Anybody that experiences apikol vs 034 rear diff mount insert pls comment. Curious to know if there's a difference. Same thing with ec alu kreuz vs 034 x brace.

I have an apikol and the 034 Trans Mount already, so all I'd "need" is the Rear Differential Mount Inserts right?

[archangel.308]

I placed my Order.... now the wait begins ... ughhhh

[034Motorsport]

Thank you for all of the orders!

That's correct! Glad you asked; it's hard to fit so much information clearly in one post.

[poweredbyaudi7]

So what is the difference b/w your front diff mount and the Apikol bushings? Will yours work with the Apikol, or does it work in it's place?

It takes the place of it, its metal instead of poly.

For the front mount for the rear differential, you have to decide between the 034 and the Apikiol option, as you cannot run both. Our inserts are made from billet aluminum that isn't prone to degrading over time. They are also designed to more closely fill the voids in the factory mounts.

Just ordered the carrier inserts. I'll post a review after install.

Looking forward to your review!

[034Motorsport]

So many orders! (Thank you!)

We still have a few of the Rear Differential Carrier Mount Inserts and Rear Differential (Front) Mount Upgrades left. We also still have a handful of the first run of X-Brace Chassis Reinforcement Upgrades ready to ship. We've already started machining more of them in case we run out, and stock should be replenished before the Introductory Special pricing ends.

[Stubek]

Been running the diff mounts on my Avant for a few weeks now. no complaints at all, no vibrations. Great!

[Lambda13]

Ordered the inserts! Can't wait to follow the step-by-step instructions!

I want the X-brace soo bad...

[KFizz]

I want the X-brace soo bad...

Yea I'm curious to get some feedback on this. I think I'd rather get a 034 part than a Eurocode one. I feel like there's just more motorsports pedigree behind it.

[blbroo]

Shite. I see a little rust under there now that i need to investigate.

The mount inserts though..



First: My bolts were hella tight and I needed a breaker bar to get them loose. (may have also been the injured rib weakening me)

Second: Use the lube boys. The inserts don't glide on in like the 034 gif shows. They draw in as you tighten the bolt (would be funnier if it was a nut).

Third: WEEEEEEEEEE. I like it

Already have the trans mount and the spulen diff mount and those made shifting crisper and the car feel more sporty. Maybe the oxygen level in the air tonight is extremely high, but these mounts made the car feel like it has 20 more HP. Throttle response is soooo much better and cornering is a joy as the rear really hooks up. A short shifter would make a nice addition now.

[eirebob]

I got my inserts in as well today ... took me about an hour. I agree with Blbroo ( Bob ); they don't just slide in. The bolt draws them in.

My bolts came loose easily. Removing them was a little more time consuming, because my socket wrench would quickly bump against the spare wheel indent in the trunk. Install was similarly slowed. No big deal, just a little more time.

I also have a manual, and would agree with 034's summary ... smoother shifting, better throttle transition. So the engine feels like it's getting to its power that bit quicker. I'm not as impressed as the other Bob, but I do like it. And no NVH issue to speak of in my 15 or so miles of driving.

Recommended; for its positive impact, modest price, and ease of install.

[Lockon_B7]

Mine were delivered Friday. However, I forgot my tools at work, so they will go in later today!

[pwdrskr]

Got mine today, install this weekend!

[blbroo]

Haha, Bob. My name is not Robert Paulson. My name is not Robert Paulson.

Will go out for a longer drive this morning to verify my initial impressions.

The best part of waking up, is car parts on your porch!

[blbroo]

Took the car out again for a hard run. Rear feels great and hooks up well. The front end now feels loose and sloppy. Not sure if all the tightness in the back transferred slop movement frontwards or if the front was always that soft and feels worse in comparison.

Perhaps these parts are some scheme by 034 to wear out our engine mounts... ;-)

[Allroad!]

Probably always had that slop? My allroad has a lot of slop & clunking going on especially at lower speeds when a/t shifts gears. The Transmission mount helped with smoother shifts at higher speeds.

Yeah. I think you are right. The rear is soo freaking tight now that I was able to kick it out taking a sharp turn from a stoplight.

Need to figure out how to tighten up the front. I think sway bars.

Well seized rotors and bearing carriers have slowed me down. The motor mounts are finally on after 6 months in the garage only to find out that the factory ones were old and didn't look bad at all... Soaking everything down and installing the carriers in a few.

Damn, well at least you have new motor mounts and don't have to worry. I think I just might order their motor mounts after I'm done with this S-Line body conversation.

[pwdrskr]

Installed but not yet driven on. Or is it driven with? No matter. Took about 30 minutes. Hardest part was the right quarters limiting the range I could move the ratchet through.

Like others, it took tightening the bolt to fully seat the insert.

Also glad to hear you like them! The inserts definitely benefit from some lube, and you can use the bolts to draw them into the mount if necessary.
