Optimal suspension tuning

Guys I have a question for ya. It may sound broad, but what exactly is the optimal suspension tune for the 8, namely the S2? I mean, I understand that first, the front end is lower than the rear, and that the spring rate in the front is much greater than the rear.

In my case, I am running 9K in the front, and 7K in the rear (i used to have 6K, but they were the shorter springs, when I went to order the longer springs, they only had 7K).

I then started tweaking with the dampening settings a bit. I understand that most people like to have their rear between "middle" and soft @ 6K, but I figured I would compensate by running full soft @ 7K. It actually used to be set on full stiff, but that was because the person who owned the coilovers before me had set them that way and i never set them back.

As far as the front goes, I am not too sure what I am running as far as dampening, but what are others running? I am thinking that the front should be more stiff than the rear, but that is just an assumption.

Thanks guys

It should be the opposite. The 8 when it was stock the front suspension was fine for me. It was the soft rear that drove me nuts. So now that I'm lowered I have the rear PSS9s at half stiff (5-6 on the dial) and the fronts at full soft. Feels great to me on any type of corner. The Bilsteins spring rates arent that stiff but good enough for the street.

And with the front being soft you don't get crazy bounce?

No. If your front end is bouncing during cornering or even just over bumnps in a straight line something is wrong. The only time I've felt a bounce from the front end is when I had front KONIs fail on another car using blasted Eiback Pro-Kit springs that were too soft. Absolutely outrageous for two products with lifetime warranties. But the first 4 months I had them before the failure they felt mint.

Oh good deal. I guess I will try making the front more soft. When I hit some small bumps it is a bit rough, hopefully I can find the sweet spot.

Ok well I just adjusted the front to be full soft. It was around the middle for damping. I will give it a shot tomorrow on my way to work. I assume its not going to drastically change the properties that I'm going to scrape those things in front of the tires right lol
