RedShift P1 Performance Coilovers 2007-13 BMW 130i/135i/128i (E88/E82) [RI-11-P1]

RedShift P1 Performance Coilovers — the S1 hardware, re-valved at RedShift for performance street driving.

The P1 Performance takes our S1 Street hardware for the 2007-13 BMW 130i/135i/128i (E88/E82) and re-valves it in our shop with RedShift-revised street damping — our own valving, the thing that sets a RedShift kit apart. A 32-way damping-adjustable monotube coilover with full-length ride-height adjustment, set spring rates chosen for a firm but livable street ride, and everything included — springs, mounts, height adjusters and tools. Every P1 Performance is valved and assembled at RedShift before it ships. Nothing additional to purchase.

Sold as a set kit — or customized (select above). As built, the P1 Performance ships with its set spring rates and RedShift performance valving. Tick Customize this kit (+$150) to choose your own front and rear rates on our standard springs; once it is ticked you can also add Swift springs (+$380). Prefer the standard street valving at a lower price? See the RedShift S1 Street for this car (this kit − $250); for revalved race damping see the RedShift Comp1W.

Springs: set rates as listed above (kg/mm) on the standard kit. With the customize box, choose any whole kg/mm rate front and rear on our standard springs (up to 10 kg/mm); rates above 10 kg/mm require Swift springs — add the Swift springs upgrade (+$380) after ticking the box. Every P1 Performance is valved at RedShift, so your rates are built in at the same time — no extra lead time.
