Reviews
Truly amazing service. I was a little worried given the price but after having my car back for a few days I can safely say it is definitely worth it. It's also worth highlighting that the staff were delightful and incredibly helpful and informative so if you have a car you really love and you want to trim out road noise (including a euro car) you should definitely consider trying these guys out.

Dimitriy was incredibly knowledgeable and recommended the perfect solution for my new Golf R. The car is over 10db quieter now and drives more like a luxury car that a VW! Feels like a tank, it’s awesome. Thank you to Dimitriy and his team!
