Bruce2009KR Posted January 26, 2017 Report Share Posted January 26, 2017 I had my local high performance shop install a McLeod RXT clutch in my stock '09 GT-500KR the other week and they advocated I turn off the traction control each time I drive it until I'm past the 500 mile or so break in period. Can someone tell me why? Have you heard this before? Thanks very much, and for what it's worth, the clutch feels great so far! Quote Link to comment Share on other sites More sharing options...
sheppd01 Posted January 26, 2017 Report Share Posted January 26, 2017 I have never heard of that. Quote Link to comment Share on other sites More sharing options...
barspen Posted January 26, 2017 Report Share Posted January 26, 2017 Doesn't make sense. TC controls the rear brakes and throttle response...nothing to do with the clutch. I just had an RXT installed and the dealership didn't make any mention of turning off TC. Quote Link to comment Share on other sites More sharing options...
andrewnagle1964 Posted January 26, 2017 Report Share Posted January 26, 2017 My TC is permanently turned off in the tune. Very embarrassing to try and do burnouts with TC on Quote Link to comment Share on other sites More sharing options...

twobjshelbys Posted June 20, 2017 Report Share Posted June 20, 2017 This falls clearly in the category of "urban legend". There is no way the manufacturer is going to tell you that you have to disable a major safety system during break in. If it were essential they would have made it so the traction control wasn't operable, with a big safety alert, during this period. Quote Link to comment Share on other sites More sharing options...

Bruce did Ford have the traction control turned off for the first 500 miles when your KR was brand new? Nope they sure didn't. And as already mentioned, traction control either applies the rear brakes or limits the throttle depending on the manufacturer so I'm not sure why your performance shop would say something like that. You can always call McLeods tech line for their answer. I would be shocked if McLeod would agree with your speed shop. Steve Quote Link to comment Share on other sites More sharing options...
KCMO-GT500 Posted June 20, 2017 Report Share Posted June 20, 2017 it is in the break in directions. It is to help ensure that if the car "over accelerates" during break in, the tires spin rather than being held firm by the brakes as part of traction control. It is all to reduce the risk of the clutch slipping excessively and having the friction material glaze, causing reduced clamping ability. FWIW, just drive cautiously the first few hundred miles and you will be fine. I love my new RXT. Quote Link to comment Share on other sites More sharing options...

FWIW, just drive cautiously the first few hundred miles and you will be fine. I love my new RXT. Ok I'm getting it now, the clutch manufacturer would rather see the tires slip rather than having their clutch slip but doesn't that seem self serving for the clutch manufacturer? When these cars were new Ford didn't seem to think it was an issue so if the clutch is installed properly why is the clutch manufacturer worried about clutch slippage? And as Tony mentioned, I'm surprised any manufacturer would state in their instructions to disable, what most non-car people would consider, a safety feature of the car. That manufacturer must have a great team of attorneys or likes to roll the dice. So it appears this turning off the TC suggestion would fall into the personal preference category, each owner will need to make the decision. I believe the last sentence from KCMO-GT500 says it best, just drive cautiously the first few hundred miles and you will be fine.

twobjshelbys Posted June 20, 2017 Report Share Posted June 20, 2017 That manufacturer must have a great team of attorneys or likes to roll the dice. Or their lawyers don't read the installation instructions and are going to get a surprise when someone slams into another car and their response as to why the safety devices were disabled is "because the instructions said to". It really just seems to make much more sense to write some sensible break in instructions (like were in the original car) or to say "don't take the car to the drag strip for 500 miles".

This reminds me of the airbag recall where some owners have claimed that mechanics have offered to disconnect the airbag for them until a replacement is available. Bad advice in our litigious society. But then again maybe some lawyers look at it as job security. The more lawsuits filed the more billable hours for them.
