4.5/5 – Fantastic street performance w/ great highway ride at a fraction of the cost of high-end coilovers.
Parts: ST Coilover Kit Part # 90873 -- 05-10 VW Golf V / Jetta V A3 (8P) 2WD, 2012 VW Jetta Sedan GLI 2.0L 2WD
Car: 2010 Jetta Sportwagen TDI
Installation: Sonic Motorsports Milpitas
Ride: I fell in to the trap, wanting the “lowered look” at the lowest cost possible. Originally I purchased a set of H&R Sport Springs and installed them over my stock struts. This resulted in the ride height I wanted… but with suspension that frequently hit the bumpstops like Terry Tate office linebacker.
After 8 months w/ stock struts and sport springs I made the move to the ST Coilover kit.
If you are considering purchasing a sport-spring kit without changing your car’s dampers… go take a cold shower, drink a strong cup of coffee, and have a long look in the mirror about where you hoped you'd be at this point in your life.
For $900.00 retail the ST Coilover kit gets you slightly stiffer, lower springs for all 4 corners paired with new, non-adjustable dampers with a matched stroke. This package resulted in a ride quality very similar to the car’s stock struts and springs on highway but noticeably reduces body roll in the twisties.
The non-adjustable dampers easily cope with most road features smoothing out cracked concrete highways and isolating chip sealed roads even with 35mm sidewall tires. For everyday driving, the dampers are fantastic. They manage to maintain the original characteristics of the car while giving you a great looking lower stance.
In corners, the dampers have more low speed compression than the OEM set up resulting in slightly flatter cornering. My 2010 JSW still understeers like a pig, but atleast now it is a composed pig.
My only gripe is with the dampers is their high speed compression. When encountering a square edge bump, the damper binds up slightly under high shaft speed resulting in a noticeable hit to the car. Even with this concern the overall ride of the car is fantastic. Avoid dropping your wheels in to big potholes at highway speed and you golden ponyboy.
Moral of the story, for $900.00usd this kit is tough to beat. The car rides great and looks even better. If you’re a California kid (admittedly a transplant from the Midwest) like me, the steel bodied ST Coils are the way to go. For those of you still living in the flyover states or where Californians go when they want to see snow, consider the upgrade to KW’s V1. They have a very similar damping profile paired with a stainless steel shock body that will have less corrosion in bad weather.
Specific to the Car: When I received the car back from Sonic Motorsports, the car’s ride height measured from the ground to the top of the wheel arch at 24”. In this configuration I experienced pretty dramatic rubbing on the inside of the front wheel wells. Don’t get me wrong… the car looked great… but it wasn’t very fun to tip-toe around corners to avoid the god awful scraping noise.
Using the included wrench, I raised the car to 24.5” alleviating most of the rubbing and then to 25” now. At 25” the car has no rubbing what so ever. You can chuck it in to any corner and lift-off oversteer your family station wagon until you heart floods over with joy.
