On a budget: a FAPO PS+ or PF kit — in stock, ships in 1–2 business days, sold as FAPO builds it. Want it assembled and verified by RedShift before it ships: RedShift S1 Street. Want RedShift’s own valving: RedShift P1 Performance. Want your own spring rates: tick the customize box on any of them.

Yes — every RedShift kit can be customized. On the S1 Street and the P1 Performance, tick Customize this kit (+$150) on the product page and enter your front and rear rates in whole kg/mm, on our standard springs up to 10 kg/mm; Swift springs (+$380) can be added once the box is ticked and are required above 10 kg/mm. Comp1W and BC Revalved kits include your rates. FAPO PF kits take the same box at +$225 (the extra covers shipping the kit to our shop). A customized kit is built to your rates at RedShift and ships in about 2 weeks.

RedShift P1 Performance — our performance street valving on the S1 hardware — or BC Racing BR if you want something on the shelf tomorrow.

RedShift Comp1W (or RedShift BC Revalved Comp1W where the RedShift kit isn’t available yet). 2-way / 3-way when the program calls for it.

Ask. Over 700 platforms today; new ones every week, and custom builds for the rest.

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.
