I just installed the stealth bolt and the metering bolt, I took the car down the road and hit the brakes...... Holy Cow!!! What a difference. I have never spent $50 and got this much of an improvment with anything I have put on the car yet.It feels so good to have the car stop the way I want it to and the way it should have from the factory.I wish I would have done a 60-0 before and after because the results would have been dramatic.As a matter of fact I am now curious how long my rear brakes will last because I know they are doing so much more work. I guess we'll see. I figure even if I have to replace them once a year it will be worth it. I have read some things about the way the car acts during a panic stop with this mod. I will be on the look out for any negative effects and I will post my findings. However for now I am very pleased.
