Aluminum Spring Retainer (SET of 2) [Reve D] RD-007-0 RD-007-2 RD-007-4 Rêve D This is an aluminum spring retainer that the development team completed by repeating tests on various road surfaces.The newly designed outer guide system suppresses the rattling of the spring and improves suspension performance. There are 3 types of lineup: 0mm, + 2mm, and + 4mm.In addition to the 0 mm type, which has the same height as the genuine down retainer of the YD-2 series, we have prepared +2 mm type and +4 mm type.Especially for + 2mm and + 4mm, the spring position is increased to positively induce the body roll and improve the side grip without impairing the traction performance. The completely lightened design by the lightening process not only improves the suspension performance by reducing the unsprung load, but it can also be used as a dress-up item.
