In the past few weeks, we've received alot of emails and concern regarding the quality of our coilover sets.
We just want everyone to know that, at this time we are selling them with a very low margin to capture market and make a reputable name for the product.
All of customers that are running the coils for the past months have been very happy with them.
The manufacturer also produces some of the top name coils in the market, and the exact same set is selling for $1399.
Background and Material usage:
Our manufacturer has 10+ years of experience in racing and R&D. We adhere to the highest quality standards by only using top quality input materials ours pistons are made out of the same SCM440 that Bistein uses (very few use the same). In addition to quality assurance, we also deliver innovation. Our adjustable cylinder features an independent hydraulic-oil chamber and air chamber to ensure that the shock absorber will perform smoothly and consistently on the road.
Our seamless steel tubes, containing chrome molybdenum alloy, will operate without flexing under high performance driving and are more durable than current market standards.
