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 soif you have a car you really love and want to reduce road noise — especially a European car — you should definitely give these guys a try.

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 than a VW! Feels like a tank, it’s awesome. Thank you to Dimitriy and his team!
