How can i say. Its a bit spongy, but not wrongly, just easy to adjust the power. When i put my leg onto the pedal, its bit soft, i use minimal power, but the car is slowin down very well...It was the same at 288s, because the cylinders are the same 57mm.
The 308s now feels better. I heard that the original saab discs are better then original opel or aftermarket brembos.
When i drive another car f.ex. combo. Not needed to "learn" how to brake with. My dad has a passat b5. 288mm stock front breaks. The pedal is firm, and hard to push. Mine is a lot better.
