I have a 1999 TJ and am considering installing some coilovers on it now as my next project. What are some of the benifits of these over the stock setup or are they just a cosmetic upgrade? Just wondering. Thanks in advance

Coilovers will replace the stock springs and shocks, and may help articulation, depending on your control arms and other suspension components. Often not a cosmetic upgrade but a performance one.

If you go with coilovers, I'd get a longarm suspension setup for better performance.[addsig]
