sorry, but this just isnt true...I'm 50 and have my Porsche lowered with H&R Sport springs and know many others with Porsche, BMW, NSX owners over 50 with lowering springs...this is just bad info. They wouldnt sell too many if they were as bad as you make them out to be...The right springs installed properly will enhance performance of any vehicle....We arent taking about slammed parking lot princesses, we are talking about functional performance enhancing lowering springs...Lowering springs are a popular upgrade for car enthusiasts of all levels. It’s an easier and cheaper way to lower your vehicle without changing your stock dampers or compromising on comfort levels. No matter your vehicle, brands such as Eibach, Tein, Vogtland, Unplugged, MPP and H&R all offer tremendous value for money options....of course, if you are tracking your car more than 3 times a year, you probably want to invest in some coilovers, but only about 2% of the population will ever track their cars.
I love the way my 718 looks, drives and feels with the H&R's I had installed a few months ago...I've had them on several of my sports cars over the last two decades and only had one car that didn't feel better with them which was my BMW F32
