MFactory / YCW Aeris Series Coilovers Ford 13+ Focus ST

$ 1,569.95


After countless hours of research into the various coilover setups currently available on the market, we noticed that there is a gap in the market for a budget setup that is: 

1) Designed and Engineered in the United Kingdom by British Engineers 
2) Offers a large choice of Linear Spring Rates, from 4K-34K 
3) Utilises premium quality service components (i.e Valving, Oil Seals, Damper Fluid and Springs) 
4) Offers local (North American, European and Asian) facilities for rebuild and servicing 
5) Fully upgradeable to our more competition-orientated 2-Way and 3-Way Coilover Kits

The target market segment for our Aeris Series Coilovers are the everyday street car that may occasionally see some track time. We basically took our Reference Series coilovers and removed components that were deemed unnecessary for the everyday street car, hence making them more budget-friendly. At only marginally more cost than the multitude of Taiwanese budget coilovers currently available on the market, you get a higher quality, better performing, British-Engineered coilover solution with an industry-leading warranty, unparalleled after-sales technical support and multi-national product servicing. Due to the nature of a customized product, we currently have a 1-2 week assembly lead time. None of the coilover kits we supply are off-the-shelf.

OEM-Balanced Spring Rates

-The majority of budget coilovers currently on the market offer default spring rates that deviate from the oem-balanced spring rates. By not accounting for Motion Ratio Calculations and just replicating race-car setups, this results in a very unbalanced and uncomfortable ride on a Street Car

-All Aeris Series Coilovers are supplied with oem-balanced spring rates, offering you increased performance without sacrificing ride comfort
