I installed the Hydratech kit on my car prior to the Nationals. After making a couple of phone calls I made the 1 hour drive down Lebanon, TN and picked up a new hydroboost system. Installation was easy and the directions were straightforward, took around 8 hours to install and bleed the brakes. The kit came with multiple hose ends and fittings for the user to decide which was best suited for the install. The 4-6 week build time is due to disassembly of the unit, painting and baking of the hydroboost unit and master cylinder, reassembly of the unit, and packaging of the kit.
