Product Details

With Independent high and low speed compression and rebound adjustment QA1s MOD Series coilovers and shocks allow you to really fine tune your handling sepearate of your bump compliance for the maximum in performance without compromise, but what really makes them cool is in all in their name. They are Modular! Desinged using QA1's Patented Quicktune Technicology, these dampers use a dry MODular valve stack that can be easily "hot swapped" in minutes, without the worry of major oil loss or contamination, and in most cases without even having to remove the shock from the car. Out of the box these and most MOD series front coilovers come with their "Medium" valve stack that is well optimized for both road and track use however if you are looking for the option for a little firmer or softer feel than the adjusters are alow for take a look at QA1's MOD Series Advanced Shock Tuning Kit part number TK111
