Racing improves the breed, And NEUSPEED's Threaded Body Coilover Sytems use the same technology that helped our NEUSPEED Accord dominate the Super Touring Racing series in it's inaugural season. Neuspeed's units feature threaded bodies that allow the srping perch to be threaded up or down to find-tune ride height and optimize handling. As true tuner components, they feature shorter shock rods, valving specific to each car model, and a percision calculated bump-stop height and hardness (shore). Only neuspeed uses massive shock rods (14mm on Acura & Honda) while competitors use the tiny 11.5mm rods that are incapable of handling side loads and whose seals leak oil. Neuspeed coil overs are the choice of champions! Neuspeed offers a limited lifetime warranty to the original purchaser, and our kids include two free billet aluminum adjustin wrenches with engraved Neuspeed logo.
