Racecomp Engineering Tarmac II coilovers
Height and 2-way damping adjustable suspension system for 05-07 STI


With the Tarmac 2, Racecomp Engineering has taken an already great product and made it better. We like KW's products and the Variant 3, but it uses a very soft progressive rate rear spring. This is great for ride comfort, but not so great for handling and will result in a car that understeers at the limit, something Subarus already have enough of an issue with. By swapping to a stiffer, linear rate rear spring, the RCE T2 results in a much better handling balance without a significant sacrifice in ride quality.

In addition to better spring rates, and different colors and labels, Racecomp Engineering has also made a few changes to the internal valving of the dampers. By using a few parts from the next level up clubsport damper and their own shim stack, these have a valving profile more suited toward track use and stiffer spring rates. At lower settings they will still offer great ride quality on the street, but are capable of handling higher spring rates and track use with sticky tires. If you are looking for a quality suspension system with an emphasis on street driving and comfort, standard KW products are an excellent choice. But for any track or auto-x use, we highly recommend the RCE version which provides better performance.

The damper housings are made from "INOX" stainless steel to prevent corrosion and have external piggyback reservoirs to increase fluid volume and cooling capacity. Adjustable spring perches are made of composite material to prevent corrosion and seizure, so you will still be able to adjust these after a few years of use. The damping is adjustable in both compression and rebound while many of the less expensive coilovers have one knob that may only adjust rebound, or have undesirable cross talk between the force curves. Having independent adjustments allows better control of both ride quality and handling performance.
