Our valving. That’s the difference.
The P1 Performance takes the S1 Street hardware and re-valves it in our shop with RedShift-revised street damping — more control of the body without beating you up, the valving that comes from the racing we do. Same 32-way monotube, same full-length height adjustment, same set spring rates, and everything in the box: springs, mounts, height adjusters, tools. Nothing additional to purchase.
Every P1 is valved and assembled at RedShift, so it ships in about 2 weeks when the base kit is in stock. Tick Customize this kit (+$150) on the product page to choose your own front and rear rates on our standard springs; Swift springs (+$380) can be added once the box is ticked. Tell us how you drive and we’ll recommend rates for free.

Questions
How fast does it ship?
In-stock kits: S1 Street about 1 week as built (about 2 weeks with the customize box), P1 Performance about 2 weeks, Comp1W and BC Revalved 5–6 weeks. Overseas-stock kits about 10 weeks by ocean freight at no extra charge, or about 4 weeks by air freight (+$300). Custom Build kits (not on our shelf yet) about 8 weeks, with custom-build pricing — see the next question. Every product page shows its live availability.
What is a Custom Build, and why does one kit cost more?
Some applications are not on our shelf. We build those kits one at a time for your car, about 8 weeks, and a one-off build costs us much more than a batch, so a Custom Build kit (S1 Street, P1 Performance or Comp1W) is +$500 per kit on a single order.
Group buys bring the price down. Get 3 or 4 customers together and each pays +$250 per kit; 5 or more and each pays the regular price. Everyone orders separately on the product page and picks the level the group reached under “Custom-build pricing”; we confirm the group with its organizer before the builds start and handle each order on its own. Want to start one for your club or forum? Contact us and we will set it up.
Are these rebuildable?
Yes — every RedShift coilover is rebuildable and every part is available separately, during the warranty and long after. See Parts & Service.
What spring rates can I choose?
As built, the P1 Performance ships with set rates chosen for the car. Tick Customize this kit (+$150) and choose any rate, front and rear, in whole kg/mm — standard springs up to 10 kg/mm, Swift springs (+$380) above that. Not sure? Tell us how you drive and we’ll recommend rates — no charge.
Warranty
RedShift-built kits carry a 2-year bumper-to-bumper warranty, extendable to 3 — every part, hard parts and consumables — for the original purchaser. Add the year at no cost by posting your install with #RedShiftMotorsports (how it works). All RedShift coilovers are for off-road use only.
NOT SURE WHICH KIT?
Want race valving instead?
The P1 Performance is the right kit for a fast street car. If the car sees real competition, the Comp1W gets our full race valving on the same platform.
