Default Reduced Tire Noise 25% by accident

Everyone here knows how noisey these cars are---I changed all of the following at the same time: 15mm spacers front, 20mm spacers rear, Eibach
springs, Adjustible upper front control arms, rear adjustable camber arms. I really, really like how the car looks and handles/ much better than stock but the neatest thing about all of this is my car is at least 25% or really closer to 35% more quiet---guys it's as different as day and night!!! I noticed the new Eibach springs have much larger coils and the weight of them is at least twice of the stock springs---maybe there is some metal harmonics going on
with the stock stuff, could be the upper control arm is acting like a tuning fork I really don't know. My car is completely different and in a very good
way--just thought I would pass this information on

You have a differently sized contact patch between the road and your tire now with all of the suspension geometry changes. Have you done an alignment? Are you in or out of spec? The contact patch size will determine most of your road noise.

Can you quantify how you are coming up with your initial noise reduction figure of 25% and then readjusting your figure to 35%?

Why do men die before their wives?

Because they want to.

"Has there been any insanity in your family?"
"Yes, doctor. My husband thinks he's the boss."

It's obviously time for some Henny Youngman jokes

Do you know what it means to come home at night to a woman who'll give you a little love, a little affection, a little tenderness? It means you're in the wrong house, that's what it means.

I take my wife everywhere, but she keeps finding her way back.

I've been in love with the same woman for forty-one years. If my wife finds out, she'll kill me.

Take my wife... Please!
