Detroit Speed's Shock Tower Delete Kits are used to close out the stock inner fender panels after removing and replacing the original strut towers. Stamped from 18-gauge steel right here in the USA, they are designed to mimic the original panels while freeing up a significant ammount of room in the engine bay for bigger motor placements and aftermarket suspension systems. Each shock tower delete panel can be either bolted or welded to the eexisting inner fender panels.
