Project MKVII Golf R: Part 3 - SuperPro Install

by Isaac Sandoval


In the last installment of project MKVII Golf R, we went over the install and initial impressions of the Bilstein Clubsport suspension system. Well during that install process, we also went ahead and installed almost every SuperPro component on offer for the Golf platform. These guys have been doing their homework on the MQB platform and have developed some really awesome parts that would be suitable for almost any application. Take a look at the parts we selected as we install them on Project Golf R.

In order to get the most out of our high-end Bilstein Clubsport suspension, we are going to replace all of the soft factory rubber bushings with some high quality SuperPro poly bushings. There is a harmony in suspension modifications, and you really need to attack it as a complete system approach rather than just individual components.
SuperPro also sent over their really impressive TRC2001 motor mount kit. This kit looks just like the factory mounts but with the highly developed bushing material in place of the soft factory rubber. This is a really nice kit. The engine mount kit includes three new mounts including a pendulum mount. The new material is claimed to deliver OE levels of NVH with dramatic improvements in performance. We can confirm that these mounts deliver nearly OE levels of NVH and make a dramatic improvement in the response and reducing drivetrain lash that can contribute to wheel hop, poor shifting, and drivetrain parts breakage. This mount kit will also work very well on the GTI model.
As we stated earlier, the best way to attack suspension modification is as a system. We are going to replace the factory sway bars with the adjustable units from SuperPro.
These adjustable sway bars are available in a couple of diameters from SuperPro. We opted for the 26mm front and the 24mm rear. These should really keep the heft of this car under control. The Golf R seems like a small hatchback, but it is quite heavy coming in around 3500 with a driver and a full tank of gas.

People always skip the simple, 'unglamorous' mods...but if you want a car to handle like a 'Ferrari'...then you need either Poly Bushings or Spherical Bearings. There is no compromise.

Ferrari's use rubber bushings...

What was the final alignment specs?

@MaysEffect - Obviously, that's not true. For one, Ferrari makes the FXX - K, a dedicated 'track only' race car. And I'm absolutely certain they don't install rubber bushings in those.


After doing some research, I did find that for street cars Ferrari utilize a bushing termed 'Silent Block' or 'Flanblock' which does suggest that they prioritize silent running and might use rubber in the design. But, this rubber is very thin (as compared to most OEMs) and is pretty stiff (shore 65-70). So, these are not your 'typical' rubber bushings found on a streetcar.

Obviously it is true. You're talking about a track dedicated car as an example. Of course it would use track dedicated suspension system. That car also uses slicks and has a full cage.

I'm talking about the road cars. And yes they do use rubber inserts. You'd be hard pressed to fine any car using polyurethane bushings or spherical bearings as standard on road cars. Even the Mclaren P1 and F1 uses rubber bushings.

Yes, a streetcar is targeting a different market, and certainly has to make compromises. It seems the OEMs are most afraid of the noise such bushings make. Which is a genuine issue. And if you really like 'quiet' cars, then I guess I would hesitate to upgrade to Poly or Spherical Bearings.

But, rubber has no place on a track car. I will say that.

I never said it did. I simply said a Ferrari uses rubber, you Incorrectly said that was wrong.
We aren't talking about track cars. This is clearly a street car still on street tires. Has nothing to do with noise either. It cost and wear rate. Spherical bearings generally don't make any more noise than rubber bushings until they fail. They do however transmit significantly more vibrations to the chassis. If that's what you mean by "noise".
