havin more pistons will inprove your braking greatly and the pressure used to step on the peddle will be less becouse you have more pistons applying force also you want to be carefull becouse the diffent volume for fluid and the pistons you may need a larger reservor and it can make diffences in the brake booster but if its desined for the car though go ahead
whereas my 86 SPG - i need to update a little you ppl with all these new cars have no real need to, even the 9-3 owners. You got PLENTY of brake powa. I wish my 9000 had half the brakes these new cars have. I really hafta stand on it to get mine to stop fron high speeds. :?
i almost never stand on my brakes. I have before and it stops pretty damnnn good. I just hate the sound of the rotors when u hit the brakes hard. I can just feel their pain as if im in the dentist chair. So i engine brake a lot and try to lay off the brakes as much as possible. There always there when i need them though
Same issue for me for my next upgrade...as I've increased power on my NG900SET considerably. So need the stopping power.
The 4 piston is the best option if your talking an overall improvement, but upgrading to stainless lines would be a whole lot cheaper, in the short run.
Just finished my stainless install, and it really does feel better. Looking at Saab Saviors front wheel 4-piston setup.. A bit costly, but might be the ticket on track days at Summit in W. Va.
