don't change. I got quoted $600.00 for a traction control system myself. Then Racelogic took it back when I started a group buy. I guess Bernie told them he was ripping you guys for 1,200USD. So they told me some horseshit and took the deal back. Really poor business practice. In addition I got contacted by Racelogic recently telling me that they would allow me to sell them now at the revised price of $724.00 USD, but that I wasn't allowed to sell to 300zx people. Obviously because Bernie is taking care of you guys, hahaha. I refused to sell the units after they made me look like a fool. I also refuse to do business with them again. I am developing a secondary rev-limiter which is all I was interested in anyway.
