These arms look beautiful, will last forever, and most importantly are an advantage. We recently track tested these arms in a back to back test with the best aluminum arms we could find. With the titanium arms the car had more right rear stick, slid less in the center, and had more forward bite. They are ceramic coated to preserve their integrity and good looks. There is a replaceable wear plate specifically designed to reduce any bind during arm travel. The pictures below show how distorted a left front arm can get on the track. This distortion happens no matter what brand or rate bar you use and this will reduce forward bite and side bite.
