Our SCCA National Championship winning RedShift Competition Coilovers are not your average street coilovers. 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.
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.
Our RedShift Competition Single-Adjustable Coilovers (shown above) are revalved to race specification that is digressive/linear or digressive/digressive-linear depending on car layout, grip level and spring choice. We use contemporary motorsport damper valving designed to WIN! These are not just stiffer street coilovers made to look like they belong on the track. Know the difference!
The dampers in our RedShift Competition Coilovers are very similar to Bilstein dampers. In fact, if you tear down a RedShift Competition damper and compare it to a Bilstein, 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.
All of our coilover kits use very high quality hardware.... case in point deep spec 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 that is used by other esteemed international suspension builders, including Ohlins and Cusco. Similarly, our RedShift Competition Coilovers use world-class Koyo radial bearings in the upper spring perches. RedShift = Quality!
Available Options on all kits:
** You may chose any spring rate you want. (Contact us for recommendations. No upcharge on standard springs.)
** Upgrade to Swift springs for $320.
** Upgrade to Camber Caster Plates (where applicable) $300 per pair
** Upgrade to Coaxial Spherical Top Plates (where applicable) $210 per pair

"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 Race-Valved Competition Single-Adjustable Coilovers)
(note that Brian is also a 3-time Solo National Champion and 2-time Prosolo National Champion)
"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 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 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 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)
"If you are thinking about coilovers, these are what I run and are fantastic. Even on the street...." - 2019 SCCA Solo National Championship SMF

"[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)
