Any way to tell if drill mod has been done?

[Fbomb]

I heard that if the drill mod (T56) hasn't been done and if you've got enough power or launch enough that it can burn out your clutch. Is there any way to tell if it's been done on a car without pulling the clutch line?

I probably need to change my fluid and bleed mine clean anyways though.

What is the drill mod Vinnie? I haven't heard of it.

There is no way to tell for sure without pulling the clutch line. Even then it might be difficult if you have never seen one done.

I dare say the only way to tell if it's been done is to take it out and see if you get any shavings when you drill it. If I recall I couldn't even tell anything had been drilled out looking at it right before I was about to put it back in.

You can tell as long as you take the entire line out of the car.

So what does the drill mod improve on? Obviously it lets more fluid flow through faster, but does it make the engagement of the clutch quicker so it doesn't burn up when your'e launching?
