We have Exedy Stage 1 clutches and lightweight racing flywheels available for your 2006 Civic SI.
The clutch is a single plate organic unit that will hold approximately 49% more torque than the OEM clutch. This piece is very street friendly as the clutch pedal feels nearly stock.
$335.00 shipped
The Exedy lightweight racing flywheel is made from billet chromoly and weighs in at 9.5lbs for fast engine response (needed on this car due to the DBW) and a noticeable improvement in acceleration, especially on a low torque motor like the K20.

Combo price is $699.00 shipped for 8thcivic members. Just shoot us a call to order :)
