When I purchased the 9-5 Hirsch Aero I noticed that the front brakes weren’t the upgraded Hirsch ones but the standard Aero specification. The previous owner had included the refurbished Hirsch callipers, larger discs and performance pads in the sale, but had never tried to fit them.

On the car’s first inspection, we tried to install them, but realised the callipers had become seized so left them off, and instead, replaced just discs with Tarox drilled and grooved ones. Over 1000 miles of so, these just haven’t been up to the standard required for the 305hp and weight of the car so we thought we’d try again.

The Hirsch callipers have all been dissembled, freed up and installed and signs are looking positive, although they are huge. To increase wheel clearance slightly we’re installing a set of 5mm MapTun spacers front and back which will also increase the overall track of the car by 10mm.

Another stunning Nappa leather sport steering wheel is also on the way from TunStyle just to finish off the interior properly. The craftsmanship is absolutely superb and really transforms the look and feel of the car which is quietly for sale here.
