Description

Coilovers ST X galvanized steel (with fixed damping)

Need to get low? ST coilovers feature a continuous thread construction for height adjustment from moderate to eXtreme! Each coilover is manufactured by KW Automotive and their expertise and know how ensures maximum quality and fantastic driving dynamics.

Once installed, the ST X coilover can be easily adjusted using a polyamide ring on the galvanized, multiple-sealed strut. Adjustment is different for each car, but typically you can expect between 35 and 65mm of lowering on both the front and rear axles. For lowered cars as standard (such as the BMW E9x 3-series) the ST X coilover features a range of 30 to 60mm (front axle) and 25-55mm (rear axle).

Improved driving dynamics and handling
Designed in conjunction with KW Germany, ST X coilovers deliver a sporty handling by reducing the car’s bodyroll during compression as well as improving agility when driving fast. The high-quality production of each ST X coilover includes a low-friction and pressure resistant housing alongside a chrome-plated piston rod for maximum longevity. A mono block guide and ST seal package ensures the twin-tube dampers remain free of dirt particles in all weather conditions.

Lowering with St\Tyle: the ST X coilovers
- Individual lowering within the tested adjustment range
- Front and rear axle thread adjustment (when possible)
- Galvanized coilover struts with additional coating for optimized corrosion protection
- Complete solution with adjustable spring plate, spring system and bumpers with dust protection
- Powerful twin-tube dampers with high-quality components for maximum longevity

Just wanted to share some love to Harry's euro and their team! Bought parts for my r32 and gti, they never disappoint. Love being part of the euro community in an ever so dominant jdm culture in New Zealand. Looking forward to bringing an rs3 in for tuning :)

I've been a loyal customer of Harry's Euro since 2017, and I can confidently say Scott and his team are the best in the game. Not only do they consistently offer the best prices, but the service is always top-notch. Scott is honest, transparent, and always takes the time to explain what’s going on with my car. Whether it's routine maintenance, unexpected repairs, or upgrades, I always know my car is in the best hands. Highly recommend to anyone looking for a reliable, expert mechanic!

Used Harry's Euro for years owning a Mk6R and now a Mk5 R32. Amazing service and delivery! R32 kit arrived today with some extra goodies! Pleasure to deal with the team!

Hands down the best Euro shop in Auckland. They've looked after 2 builds of mine, and the parts, service and expertise has been top notch.

Harry's Euros delivered platinum service from start to finish. The quality of the products is excellent, and the install experience was smooth and professional. If you want a lower cost acceleration boost ask Scott about a Pedal Box! Huge difference and very simple to use.

Got some basic servicing and a Stage 2 transmission tune done today to match the ECU tune. The team was really helpful with information, communication via email, fit me in quickly, and offered fair, industry standard pricing for a specialised shop. Highly recommend, and I'll definitely be back!

Great service. Needed a replacement driver's side mirror glass for our old GTI. Harry's Euro had it in stock for a good price and shipped it next day. Very pleased with the transaction and will happily recommend and use them again.

Been Working with Harry's Euro for almost 3 years now and I can highly recommend any auto-work or performance upgrades to be done by these guys. I've had my previous car and my current done by the team cheers to Scott and the boys for the work 🍻
