Why we have this car is worthy of an explanation. In 2011 we were looking for a car to demonstrate how SuperPro can be used and what the benefits are:- precise & communicative handling, durability & alignment consistency while not creating a harsh ride quality or increased levels of cabin noise and vibration.

The key requirements were a car that was relatively old, around 8-10 years, have a reasonable number of miles on the clock, 80-100K, and while not heavily modified it should be a car which would interest the widest possible audience including the die-hard enthusiasts in the performance & tuning world. At the same time SuperPro had been endorsed by Subaru UK as a part of the Pro-R programme so a suitable Subaru with sporty pretensions would be perfect.

In 2011, we found our World Rally Blue 2003 Impreza WRX – 8 years old with 90K on the clock & only a few modifications – most of which we took back to standard before fitting a full SuperPro bush kit.  We fitted the SuperPro bushes and 2-3 thousand miles later a set of new Pirelli’s and used it as a daily hack. In the 20 months or so since the car has completed 35,000 miles of motorway & enthusiastic cross country driving. The car is exactly what we had hoped for – and a lot of fun.

Those who are familiar with Impreza’s will be aware of their hunger for rubber - you can read about how we solved this issue here. We have heard stories of lightly used daily drivers only getting 20K from the front tyres and more heavily modified & harder driven cars struggling to get past 10K. The issue is the effective 4WD system coupled with a powerful turbocharged engine. The result is movement in the front lower control arm rear bush allowing the wheels to toe-out under acceleration & scrub-off the inside edge.

So what were our tyres like after more than 30K hard miles?
