If you want the feel of the OEM clutch and don't plan to install an SC or TC, then you might want to consider replacing your clutch with an OEM or an aftermarket street clutch such as the Comptech Powergrip 1. If, however, you have, or plan to, SC or TC your X, you should definitly consider the Comptech Powergrip 2 (PG2). The PG2 is what I installed on my car after my SC proved to add mor ponys than the OEM could handle. It has a bit smaller sweet spot but handles the power nicely and I am very happy. If I'm not mistaken, the PG2 cost me ~$2,500 installed at my local dealership.
No, I'm not associated w/ Comptech.
