To be honest, I am a fan of the Swiss company that produces first-class products for Saab. Hirsch products were used both in my current Saab 9-5 Biopower sports trolley and in my previous Saab 9-3 Aero Cabriolet.
Currently not all Hirsch products for the previous Saab 9-5 are available. The products which are in stock are sold off, a reproduction will presumably and regrettably no longer exist. So there is no longer the famous sports steering wheel, even the highly recommended chassis is unfortunately only available for the Saab 9-5 sedan.
The Hirsch exhaust systems for the sedan and the Saab 9-5 sports suit are available and definitely worth the money as a long-term investment. Likewise, the wonderful aluminum sports pedals, which you don't have to have, but which you should have. Because with the embossed “Hirsch” logo, the sporty pedals enhance the gray interior.
So if you have one of these parts on your wish list, you should strike because it's gone - gone.
The brake system from Hirsch brings the Saab 9-5 to Porsche (brakes) level, however the brake system is only available with 18 ″ rims and is therefore a question of the wallet. Sports brakes from Maptun.
For the time being, the performance upgrade for all Saab 9-5 of the first series remains available without restriction. The increase in performance is definitely worth an unreserved recommendation, because in addition to more sovereignty and safety, the Saab 9-5 becomes considerably more turbo and even more Saab and even more driving fun. One of the positive side effects is that this reduces the average consumption.
The big plus point of Hirsch Performance is the dealer density, as the factory-approved tuner, there are deer parts about almost every German Saab dealer.
I think even older Saab 9-5 can take a performance boost from Hirsch. Anyone who has questions should contact Hirsch directly. In my experience, customer inquiries are answered quickly and competently.
