* Required Fields


This is 034Motorsport's new line of MOTORSPORT Mounts made specifically for B6-B7 V8 Audis. These are a pair of Engine Mounts for B6-B7 Audi S4s and B7-RS4s.

034Motorsport's Motorsport Engine Mounts are the new standard in track performance. Their mounts are engineered with racing in mind and manufactured from billet aluminum and high-durometer rubber for the ultimate in performance and durability.

The result is a locked-down drivetrain, solid shifting, and virtually no wheel hop. Although these Motorsport Line mounts will cause a noticeable increase in noise, vibration, and harshness (NVH) inside of the cabin of a 4 cylinder or 6 cylinder car the increase on the smoother running V8s isn't that bad. So if you are looking for a fully-encapsulated mount that will give you extremely limited engine movement, this is the mount for you!

- Manufactured from Billet Aluminum and High-Durometer Rubber
- Lifetime Warranty **
- Rebuildable Design

- Reduced Drivetrain Slop

Please note: Available with 8mm and 10mm mounting hardware. The stock mounts use 8mm studs. We recommend upgrading to 10mm studs if you plan on launching your car and/or drag racing. Upgrading to 10mm studs will require drilling the stock engine mount brackets. These mounts cannot pivot once installed and bolted firmly in place.

OPTIONAL: Electronic circuitry disabled, if you do not want to have codes stored in your ECU please purchase 034-708-0000 for a resistor to install. 1 per mount needed. This does NOT cause a Check Engine light it is just a soft code that some people do not like to have.


**Limited Lifetime Replacement Warranty against failure from manufacturing defects. Applicable to the original purchaser only. If any part of the mount fails under normal use, upon 034Motorsport approval, replacement part(s) will be shipped at no charge to the customer for installation.

Happy! Had to get used it it...
To be clear I am very happy with the performance of the mounts thus far! much firmer and makes the car feel solid. I had to get used to the side effects of the mounts which honestly freaked me out a bit. You feel a LOT more of the engine compared to stock. Sometimes at idle the engine just ever so slightly dips a little lower is the RPMs and "shudders" (for a lack of a better term). Before I didn't feel much vibration, now it is quite evident when this happens. I want to say I can feel the individual pulses at idle. around 1,500rpm I definitely feel more vibration but otherwise it isn't bad at all! Haven't gone above 4,500rpm because I'm wearing in the new chain tensioners.
I will have to find a way to keep the sun visors from rattling
