2008 GT500 Diff Leak after tracking or agressive driving. Help ???

2008 GT500 Diff Leak after tracking or agressive driving.

I am running a 08 GT500 with a Saleen Watts Link on the rear (Dont think this is the issue). After my first track day I noticed lots of diff fluid leaking or dripping off the rear diff after 10-15 laps at Laguna Seca. I took 5-10 more laps and then called it quits because of the amount of diff fluid leaking from the breather on top of the rear diff.

I took the Shelby to the dealer for further inspection and they mentioned that the fluid might be too high because its leaking out the breather on the top of the diff cover. I had the level corrected and went back to Laguna today. After 5-10 laps I had diff fluid dripping from the read diff/axel again and called it quits.

I have the shelby in the shop again and I guess I will just have a hose and overflow/catch can installed????????

Any others with info or solutions? I have read many others with this problem but no solutions yet?

Thanks in advance.

update.

ok so I heard that the KR's are comming stock with a differential fluid expansion tank. I just went down to look at one and indeed they have included an overflow on the new GT500 KR diff.

I am looking to see if the KR's differential fluid expansion tank can be installed or I will just get something fabracated for mine.

Thanks for the input, I am in the process of installing the catch can now.
