As with all X-1 coilovers Geoff’s Choice coilover sets feature some of the most advanced, most thoroughly R&D’d valving profiles in the world. Our European style digressive valving provides damping force in all the right places. Stiff low speed gives you incredible handling and driver feedback with minimal body roll. High speed tapers off as shaft velocity increases which keeps the car composed on the track if you hit a curb or less than perfect surface. Particularly in this price range most coilover sets make a lot of compromises with damping force at high and low shaft velocities. With the X-1 you truly get the best of both worlds which provides a track capable setup that will go toe to toe with European options that cost significantly more money and don’t have support that is half as good in the United States. Aside from having one of the best digressive valving profiles at any price point these coilovers feature a wide rebound adjustment range. This allows you to dramatically change the characteristics of the coilovers simply by clicking the damping adjustment knobs (contrary to popular belief the number of clicks is not important. It’s what these clicks do that is important, and the range you find on the X-1 is larger than anything else in this price range). This range also makes the coilovers extremely modular because it allows you to modify spring rates in the future if your goals with handling or ride quality ever change.
The components we use are the best that money can buy. Pistons are both developed and CND’d in the United States. Shims are imported from Sweden and are made from some of the best quality steel in the world. Oil is either sourced from the United States or France depending on the application and valving profile. We use a high viscosity index group 5 synthetic ester based oil for long shock life and the ultimate consistency. Whether you are pulling out of your driveway on a cold January morning in Alaska or turning fast laps in mid July in Arizona our coilovers are exceptionally consistent. Bearings, shafts and seals are sourced from Japan. Every component has been selected specifically for long life and consistency.
This Geoff’s Choice coilover set comes standard with Hyperco springs. These are the same springs you will often find on $12,000 coilover sets for a reason. They are arguably the best coilover springs in the world, and they are considerably better quality than the springs other coilovers in the X-1’s price range are typically equipped with. Hyperco uses different coil wire diameters for every spring rate which allows them to optimize the design of each individual spring. This is not something that most other spring brands do. When you couple this with the best quality spring steel in the world you get minimal distortion and maximum accuracy. A spring that does not distort much (increasing rate upon compression) rides noticeably smoother. A very accurate spring provides noticeably more consistent handling. The car feels the same at the beginning of the corner as it does at the middle and end of the corner. It feels the same turning left and turning right. A spring may seem like a simple part, but high quality accurate springs are mission critical when it comes to getting the most out of your suspension. Every Cygnus Performance Hyperco spring is fully cycled and blocked at the factory five separate times to avoid any potential sag or settling. Each spring is 100% made in the United States and features a lifetime warranty and industry leading plus minus 2% tolerance guarantee.
10k front and 9k rear spring rates. After selling tens of thousands of coilover sets for these platforms we have found these rates to be a great option for customers who want to prioritize the best possible handling and minimal body roll.
The ride height range on this long travel set of coilovers is 0.4″ higher than stock ride height at the highest setting to 2″ lower than stock at the lowest setting. These longer than typical coilover shocks offer many functional advantages including increased stroke, increased droop travel, increased oil capacity and increased heat dissipation surface area. These are all good things when it comes to consistency, handling, ride quality and shock longevity.
All Geoff’s Choice coilover sets come standard with Cygnus Performance High Caster Camber Plates. These are the best camber plates on the market for your Subaru. They feature a best in the industry 1.2° of positive caster which has many benefits including better dynamic camber characteristics, more front end grip, less understeer, better tire wear characteristics, better on center steering feel, better overall steering feel, better straight line stability and better high-speed stability. Improving straight line stability is particularly beneficial when you lower ride height since this throws off factory steering geometry.
Cygnus Performance High Caster Camber Plates are also an extremely well made plate. They are very thick with fully recessed hardware and dual camber adjustment channels for more rigidity and strength than anything else on the market. Zero flex even with hard hits means a better connection to the pillow ball housing. No issues with hairline cracks or catastrophic failures like you may have seen with other brands. Zero flex also means incredible driver feedback and handling. They are 100% made in the United States using US sourced raw materials.
This set includes the Motorsport Shock Upgrade which consists of heavy duty triple bolt spherical housings with 50% more clamping force as well as clamping style ride height adjustment locking. This is an excellent upgrade with no downside. It will ensure years of easy adjustment, and it nearly eliminate any chance of these adjustments moving or slipping.
