What you see on the pictures is our control arm/bushing set with the only purpose of giving you superior adjustability and stiffness to your rear subframe. This kit will give you +/-25mm adjustment compared to the length of a standard control arm which is enough for every setup with either Drift, Time Attack or Stance requirements. Features: - 16 pcs. Chrome-Moly Steel Rod Ends with Teflon/Kevlar injection molded Liner (8 right and 8 left hand thread) - 8 control arms made of 7075 Aircraft grade aluminium - 30 pcs. press fitted Stainless steel cones for the Rod Ends - 4 Polyoxymethylene (POM) bushings for the Rear Subframe (OPTIONAL) The kit is manufactured to use m12 mounting hardware and can be used with the stock m10 with OEM sleves but we don`t recommend on doing so! All of the above mentioned materials are tested on our drift/training chassis for years. Their durability in time has proven to be the best motorsports choice. We do not recommend this kit for daily use and harsh weather conditions! The kit does not feature lower control arm to which the coil/spring is attached because the forces there are immense and there is no small enough element that can swap the stock rubber bushing and sustain these forces long term! NOTE: the toe arm requires the knuckle to be drilled to 14mm and an m14 bolt to be used there (or the imperial equivalent)
