Description
Details
Features:
• Full length adjustment system on lower mount
• Separate ride hight and pre-load adjustments
• 6061 T6 Aluminum alloy construction: lower mount, top mount, spring seat and locks
• 12 level adjustable damper - adjustable dampers allow fine-tuning of the suspension stiffness to best suit the driving condition.
• SCM440 hardened piston rod: special high strength grade material with extra hardening process effectively improves the chances again deformation, fracture and leakage.
• Special formulated oil – stable and durable high quality oil seal can minimize any suspension failures or oil leaking to increase durability.
• Inner polished seamless steel tube – quality high strength tubes ensure the strength of the struts (cylinders). The micro finished inner surface ensures a precise and smooth action, which can reduce the chances of fluid leakage and prolongs struts endurance.
• Mono tube design ensures quick response and comfort. suspension fluid is separated from high-pressure gas in order to reduce damper failure.
• Advanced formulated rubber parts: effectively increase the endurance and help eliminate abnormal noises.
• Forged aluminum alloy top mount: increases the strength and effectively reduces the weight to provide sensitive driving feedback.
• SAE9254 spring: high strength material formed spring effectively minimizes deformation.
Spring Rate: Front 7K | Rear 8K.

I do have these on my 3 Series, and I do love them.
Plus, they helped keep my car stable at the track. |

Will do! Thanks man.
And the gents over at Sonic Tuning have been awesome thus far. Had a tracking # about an 30-60 mins after I sent the payment info, and they're quick to respond to emails. Hopefully the product lives up to the customer service so far. |
