These Konis have at least 100,000 miles on them. They all squeak and seem bottomed out yet bounce on corners.
The numbskulls that installed them on the TL Sport didn’t put spacers on this portion of the rear coil, so the fork was squished together from 50mm to 47.3mm. That was because the fork was pulled together by 5mm to hold the trashy Koni struts.
