To your question of whether the additional $500 is worth getting the Ridetech kit, I can't say. I suspect that with right parts, knowledge and labor, my car's ride could have been obtained less expensively. However, since I have neither the knowledge or time for the labor, I liked that this kit was all inclusive. Like others posted, good shocks are pricey. These were $185 each if purchased separately. Add in the Delrin bushings, sway bar, progressive coils and light weight composite leaf springs, it adds up.
