I never said that the coil over systems won't hold up. I said that the cars were not designed for them. I also said that if 'I' were to use one, I would look to implement added structure to the car - exactly what I don't now know, because I have no intention of doing such a thing and so have not done the aformensioned homework so as to know what would be needed. I also said the cars might well be built to withstand the added stress. And I also said that I would not be willing to test that out. 30K miles is not a lot of miles when you consider that these cars often last 200K+ with the stock componenets. I said further that it depends a lot on the year, condition and usage of the vehicle. Best regards,
