I have a 91 foxbody and have kyb shocks on there right now that feel like they need to be replaced. I was looking at some Koni yellow shocks and was wondering if they were any good or if anyone has anything better. I'm looking for something that just gives me a nice ride since I do drive the car every day and that it doesn't feel like im driving down a dirt road all the time. Also if I do go with the Koni shocks I was planning to replace the coils as well and wanted to know if they work better with some coils then. Thanks
