Hate to burst anyones bubble but Puerto, how many miles do you have on the Koni's? I installed the FSD's on a 540 sport and a 328 sport. No problems on the 328, but on the 540 with the high rate springs and heavy engine (diesel 6 weighs about the same as the gas V8) the front FSDs were totally shot in 12K miles. The bump stops were the only thing keeping the car on the road. Koni did replace them with yellow adjustables which have been fine ever since. But there were many others with the same issue. Was it a manufacturing issue or a design issue that the FSD's cannot handle the service of high rate springs and a heavy engine?
