I would take this as an opportunity to upgrade the rear brakes to the 9-5 ( as you know, the 9-3 Viggen already has 9-5 brakes on the front! ) Nick T , Genuine Saab has a good kit to do this and you can get used, new or rebuilt calipers. It really improves the brake balance and is very significant when braking, especially over 60 MPH! Nick can supply the larger diameter OEM rear 9-5 rotors ( the best ) grooved to match the front viggen rotors! BTW, drilled rotors are passe now and grooved is the way to go! Virtually no one uses drilled anymore as they can crack it has been found! The lights you seek should be avail fr Saab parts suppliers. Instead of paying for pixel repair ( which we used to do ) I have lately been having friends near a pick and pull score me one used! About 2/3 seem to still be good and the junkyards call it a radio and charge as low as $12 ! LOL ...........................Sorry have no idea what the whine you have is? regards, Neil .................PS for brake pads? We like EBC yellow stuff brake pads. Awesome stopping power and they work well from cold which is amazing for a race compound type pad! They will wear faster than others but what is your life worth? Yes, they have medium / high dust ! We know how to clean a wheel ! Don't be lazy ! The awesome stopping performance is well worth the extra work! We got them from an E bay seller and got the optional, ( actually very cheap) protection plan they sell so got a free set for the wife's honda civic as we wore them out in less than a year! very LOL! ...............................................................................BRAKESCHASSISDETAILINGENGINE CONTROLENGINESNEWSPOLITICALRACINGSUSPENSIONTIRESTRANSMISSION
Rotors: Blank vs Cross Drilled vs Slotted and Warping
John Milmont on April 11, 2012 — 54 Comments
There is more misinformation about cross drilled rotors than anything else I can think of on a car. The general consensus seems to be that drilled and slotted rotors offer better performance than “blank” rotors. This is simply not the case.
At one point in time race cars did have cross drilled rotors, and this is probably where the idea that they offer increased performance came from. But if you look at any serious professional race car today, I would be shocked if you found any cross-drilling.
Like everything else, there are advantages and disadvantages to drilling and slotting a rotor. Fortunately, technology has progressed so that there is no longer a need to cross dill rotors and therefore, we don’t have to deal with its disadvantages.
The reason why rotors were drilled in the first place was to relieve the gas that was created when the pad material started to breakdown (burn). Since modern pads don’t gas off any significant amount, this is simply not a concern.
Many people and advertisements claim that cross drilling helps the rotor cool. I’m sure those little holes do help the rotor cool in some regard (possibly not measurable), but the effect, in reality, is completely insignificant. Furthermore, any benefit of extra cooling is most likely offset by the reduction of the rotor's mass due to the drilling which lowers the overall heat capacity of the rotor.
So now that you know that there is no benefit to running a cross drilled rotor, we are left with a major disadvantage. What all of those little holes do is create stress risers and a surface that’s unevenly heated and cooled. The result is that the rotor becomes very easy to crack and makes a catastrophic failure much more likely. The worst situation is when a crack forms and connects between multiple holes – much like a connect-the-dots puzzle. This can lead to a large piece of the rotor breaking free which I can assure you is not good at all.
So why do all those high dollar cars like Ferrari, Lamborghini and Porsche have ( HAD - mostly ! ) drilled rotors? Well, because people think it looks cool. The rotors on those cars fail when pushed hard as well, and the professional race teams that run these cars replace them with non-drilled rotors. In my experience, cross-drilled rotors just don’t last as long as a blank rotor. If you ever go to the track and find someone pushing a car hard that has cross-drilled rotors, put your ear near one of his wheels and listen carefully when he gets back to the paddock. You will hear small metallic pings and pops as the rotor cools unevenly. What you will be hearing is the sound of the cracks forming…. PS our Ferrari , ( 2008 ) has carbon rotors NO holes or slots !
