Safe? Depends on what you mean.

Safe to your license, probably not.

Safe to your wallet, nope. You'll want to upgrade the tires, suspension, and
the brakes, and your radar detector.

Safe to the mechanicals? Absolutely. For more information, check out

Also, check out www.intendedacceleration.com for a second option.

First step runs around $700 or so.

HTH,
