Good choice for the PSS9 system. The PSS9 system feature true coil-over struts with custom monotube gas shocks and progressive rate coil springs. CNC machined aluminum adjustable perches allow quick and precise front and rear ride height adjustment. The PSS9 system gives you a selection of nine precise compression and rebound settings so you can go from sport to competition within a few minutes.
I do not know anything about the Milltek manifold, but i know the Supersprint exhaust package is a great choice.
