It makes more sense to get an lsd for improved grip.
The point has already been made that this is not the Renault system and it is more advanced in being able to program the amount of slip the system allows before it intervenes also things like full throttle gear shift and launch control

.
I have had no TC in my car for 18 months it has cable throttle so is more sensitive then FBW and has 200bhp, soon to be 220bhp. So yes its not a 12000bhp supra but it is a powerful FWD car with the problems that it brings ie power understeer. I am not an inexperienced 17 year old either and have been driving performance hot hatchbacks for 12 years (I learnt the meaning of lift off oversteer in a 205gti that I got when I was 18

)
I dont think anyone on this forum can claim to be infallible when driving there cars, and hopefully the more experienced drivers are even more concious of driving on the cars limits especially on the road.
Mark I didnt want it because it would allow me to press my foot to the floor everywhere without fear of a crash that would be boring and stupid. But for the safety net of being able to say right I can push but if I reach the limits of my skill (not hard) I have a backup. You still have to drive the car round corners and on the brakes its only going to be helpful in the wet when accellerating in first and second.
I am not trying to justify buying the system but do question the way people dismiss TC as a system used by people who cant drive. How many forms of top motorsport use TC to enhance there lap times?
