Wavetrac Limited Slip Differential – Install and Review in a mkIV GTI

While most people think of cars being either two or four wheel drive, the fact is, cars with open differentials are one wheel drive. Very few cars come from the factory with limited slip differentials. With power constantly on the rise, cars have quickly outgrown the outdated open diff.

Enthusiasts haven’t had too many choices in the past for aftermarket differentials. A specific car will usually only have a few different manufacturers of aftermarket diffs. Autotech Sport Tuning in Aliso Viejo California is trying to make the market a little bit bigger. We recently tested out their new Wavetrac differential in a Volkswagen GTI 337 and came away very impressed with not only it’s performance potential but use in daily driving.
