No not on a front wheel drive car, I was struggling for grip as it was and it will be worse now(until I get Yokohamas). So to go to the bother of a big laggy GT28 I just didn't see the point. But mine has still to be tested and the head guy at Turbo Dynamics is very interested in the results. Pat at Primary designs is also very interested in the results and wants me to go down there and have Superchips custom map my bluefin for all the new modsn and get dyno readout to compair mine with the other cars he's done.
