You can use the OEM struts - but you will wear them out very quickly. To get the most out of performance springs, best to pair them with performance struts that were designed for lowering applications.
OEM ones will work in the short term - but can wear out as fast as a few months. That means you will have to take the springs off, replace the struts, and reinstall them again. For some - they don\'t mind the work, especially if they do it themselves. For others - that means paying someone twice to do one job.
