No down side to clear bra.Th best product out there is EXPEL EXTREME.You can barely see it on your car.A must on all the leading edges the complete lower rockers behind the rear wheel arches etc.Pulley and tune is great .But you must have Torrie tune your car or bring to dyno and have tuned to your motor. Its the best bang in performance for your dollar. This is all my 02 for the record.Oreder the Project 21 products since they are doing another run.
No drilling for the Stillen mud flaps.Highly recommended !
ty bra and flaps for sure, I live by the gt guys and have called them going there soon
