The IS is not designed, built or marketed as a 'street racer'.
What were you're reasons for buying an IS?
Did you test drive one before you bought it?
Not having a go at you mate - just makes me think maybe you bought the wrong car if racing Saxo's on the street is what you want to do. (which I really don't agree with btw).
When I said about Saxo’s etc. I said it for example. I don’t understand the reason Lexus engine gives only 155hp in 2lt and other cars like Impreza WRX and Focus RS gives more than 220hp!
My requirements in my car are: back wheel drive, time-honored, trustworthily, good power in engine and to be comfortable in driver seat (I’m 6’8” height :) ).
So the only car that completes all my requirements is IS 200. :)
Usually I’m using my car for racing in racing-tracks, in the street I’m just driving fast ;)
When I went to see about IS 200, the car salesman told me this car is ideal for racing. I drove it before I buy it, but I drove it in the city and not at the racing-track.
But surely i don’t I regret buying IS 200. :) I ordered last week and I gonna have it in the end of this year.
Next year I’ll upgrade it installing the compressor. ;)
