"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 BC Race-Valved 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 or MCS dampers, our custom RedShift Competition Coilovers use true motorsports damping curves to provide 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 - with RedShift BC Race-Valved Competition Single-Adjustable Coilovers) in his GTI ran 4.3 seconds faster at Mid-Ohio, 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 BC Race-Valved Competition Single-Adjustable 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 RedShift BC Competition Single-Adjustable Coilovers are available in Sport or Race valving. The Sport valving is made for street performance and is best for low to medium stiffness spring setups where comfort is of some importance (like on a daily driver). The Race valving is digressive/digressive or digressive/linear valving that is designed to win autocross and track events and is NOT just stiffer Sport valving; rather we use contemporary motorsport valving strategy seen normally only in real motorsport dampers. The RedShift BC Competition Coilovers are also available in Double- and Triple-Adjustable versions with external reservoirs and large shafts for maximum fluid flow to the base valves. The Double-Adjustable adds a compression-only bleed adjuster for changing low speed compression damping. The Triple-Adjustable has 2 compression adjusters (bleed and spring preload) for low and high speed compression damping changes.

In addition to the above, we also offer the RedShift MCS Competition Double-Adjustable Non-Remote Coilovers utilize the world-renown "Motion Control Suspension" dampers that incorporate separate compression and rebound damping adjustment into the main body of the shock; so no external canister is required. This is a fantastic shock that makes it easy to run a double-adjustable damper without the headache of having to mount external canisters! Also available are RedShift MCS Competition Double- and Triple-Adjustable Remote Coilovers. All RedShift MCS Competition Coilovers use spherical bearing upper mounts and helper springs where needed (struts). For more information on the dampers used in these coilovers kit, please see the MCS website here. https://motioncontrolsuspension.com/




"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 on RedShift BC Race-Valved Competition Single-Adjustable Coilovers)


The dampers in our RedShift BC Competition Coilovers are very similar to Bilstein dampers. In fact, if you tear down a RedShift BC Competition 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. The dampers used in our RedShift MCS Competition Coilovers are authentic MCS dampers, built by MCS is Georgia (USA) for the most serious racer. MCS dampers are absolutely world-class and are very common at the professional level of motorsport, and now we offer those same pro-level dampers in our RedShift Competition Coilover kits.

All of our full kits use the very high quality hardware.... case in point is the NMB
MBWT18 spherical bearing used in all our camber plates that has an extremely high axial load rating of 7,495lbs (higher than most other name brand camber plates). This means we are using the same spherical bearing as several top international suspension builders, including Ohlins and Cusco. Similarly, our RedShift Competition 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 BC Race-Valved Competition Single-Adjustable Coilover cars (18 car ITA field)
-Sean Grogan (1st Gen Dodge Neon)




"[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 - RedShift BC Race-Valved Competition Single-Adjustable Coilovers
