"First off, wow! What a transformation they made in the car.... I am super impressed..." - 2019 SCCA Time Trials Nationals (Class T3)
-Brian Kuehl (After running his 2007 Cadillac CTS to fastest lap at the 2019 SCCA Time Trials National Championship with our off-the-shelf the RedShift Competition Single-Adjustable Coilovers)
(note that Brian is also a 3-time Solo National Champion and 2-time Prosolo National Champion)

Our SCCA National Championship winning RedShift Competition Coilovers are not your average street coilovers...not even close. Like other serious "motorsport" damper companies, we use a different balance and shape of compression and rebound damping curves than what off-the-shelf coilovers use. Based on the world-class BC Racing coilovers, our custom RedShift Competition Coilovers use digressive compression damping, linear rebound damping, and large shaft sizes for maximum grip.

"I owe you a thanks for the great season and product. The body control gained over the off the shelf BC’s I had before your product is amazing. ....The dampers didn’t need any major fidgeting to get them dialed to how I felt most comfortable. A few clicks off center was all I needed, after the initial corner weight and alignment. The way the car handles curbs and bumps is worlds better. Turn1 at MidO when a little early turn in or getting around traffic puts me on the curb the car stays settled and composed. Turn 10+11 at Pitt race with the curb then bump the car stayed settled enough to keep the skinny pedal buried, something I was never able to do before. ....Finally best of all taking 4.3 seconds off my PR at Mid Ohio Pro Course. This was good enough to almost land me 3rd or 4th at NASA Championships in ST4..... Anyway thank you for the great product."
- Nick Simon (2019 NASA Championships - ST4) in his GTI ran 4.3 seconds faster at Mid-Ohio with our single-adjustable coilovers, had several wins, and was on pace for a 3rd or 4th in ST4 at the NASA Championship race until being taken out.

We tune the compression damping to do more work in controlling the mass of the car (sprung weight), and this in turn reduces dive under braking, improves turn-in, increases traction through the turn, and significantly improves your ability to feel the car and hit your marks on course. Rebound damping is made linear (and relatively less than street coilovers) so that the tire stays in contact with the surface for better grip under braking, at turn-in, through the turn, and for the drive wheels at corner exit. The RedShift Competition Coilovers are designed in every way to win races.

"We drove a full prepped STR S2000 last night with Ast’s back to back with my car. Same spring rate.... myself, Adam, and Simmons, all thought that my car [with RedShift Competition Coilovers] handled a lot better. ....Shocks really did feel good yesterday. Backend was stable. I felt more comfortable driving it aggressively."
- Chris Haydu (2013 SCCA Solo National Champion - STR Honda S2000)

Our Single Adjustables have a bleed adjustment that affects compression and rebound damping together, with the balance tuned for your specific application. Our Double Adjustables (with remote canisters) adds a separate 24-position bleed adjustment for compression only so you have more control over the balance of compression and rebound. Our Triple Adjustable (with remote canisters) adds a additional high-speed compression adjustment for those who want precise compression damping control. All of these shocks allow you to run the shocks at various levels of stiffness so you can optimize your setup for a high-grip or low grip, sun or rain, warm or cold, and smooth or bumpy surfaces. This combination of a quality coilover, large shafts, race valving, and price make for a tremendous value for a world-class race coilover!

"If you are thinking about coilovers, these are what I run and are fantastic. Even on the street...." - 2019 SCCA Solo National Championship SMF
-Jeremiah Thomas (2019 SCCA Solo National Championship in his 2007 Mini Cooper S)

The dampers in our RedShift/BC coilovers are very similar to Bilstein dampers. In fact, if you tear down a RedShift/BC shock and compare it to a Bilstein shock, you will find they share many dimensions. Also, the internal parts are very similar and, in some cases, better than the Bilstein equivalent. So, these are not "low-cost junky" coilovers, in fact they are very well designed and built, and when considering the price, they are exceptional. Also, the hardware used is extremely good.... case in point is the NMB MBWT18 spherical bearing used in all our camber plates and spherical top mounts that has an extremely high axial load rating of 7,495lbs (higher than many other name brand camber plates). This means we are using the same spherical bearing as Ohlins, Cusco, Apexi, and several other very durable products found in Europe and Asia. Similarly, our RedShift/BC coilovers us world-class Koyo radial bearing in the upper spring perches. These are not made to be cheap....they are made to give you many years of amazing performance.

" ...this suspension is awesome. Best weekend of racing ever....." - July 14, 2019 SCCA ITA Road Race - 1-2 finish for RedShift Competition Coilover cars (18 car ITA field)
-Sean Grogan (1st Gen Dodge Neon)

More Specs
Single Adjustables use 20-22mm shafts for struts and 18-20mm shafts for shocks.
Double and Triple Adjustables use 20-22mm shafts for struts and shocks for highest fluid flow to the base valves in the remote canisters.
** All shocks are nitrogen charge adjustable with the proper tools (sold separately)

"[After 2 years of use].... lots of autox and track events, plus around 20k street miles.... Nothing but great things to say about the suspension. Car felt better than ever, and lots of people were commenting how composed it looked while bouncing off the curbs." - 2019 SCCA Time Trial Nationals (T4)
- Justin Tilus (2007 Honda Civic Si) - 2018 SCCA Time Trials National Champion T4

** Bilstein shock piston available for additional $300 (the Bilstein piston is excellent but not necessary).
** Upgrade to Swift springs for $320.
** Chose any spring rate you want. (Contact us for recommendations)

Satisfaction Guaranteed: We are serious about making you extremely happy with your purchase; so you may send any shock to us for revalve at any time within the first year of ownership. You will receive priority 1 week turn-around to get your car back on track. This offer is extended to the original owner only.

"....only a few tenths off the leader, and we were multiple second back previously [before the RedShift Competition Coilovers]."
-Nick Babin (2016 Mazda Miata Club - SCCA Solo STR Class)

Warranty: RedShift Motorsports warranties all RedShift Competition Coilovers for 1 year from the date the customer receives the coilovers.
(After the 1 year warranty period is up, it's important to recognize that getting parts is extremely easy and affordable. As of the time of this writing (10/25/19), the cost of a brand new BC Racing shock is $95, lower mounts are $50 each, and spring perches are $7.95 each.... and most are available for same-day shipping from BC North America's 40,000 sq ft headquarters in Florida. RedShift's shock service labor cost is $75 per hour; so most service will not be terribly expensive.)

** All shocks dyno-confirmed on our in-house dyno before shipping to you.
