That's not duct tape, that's black electrical tape.... remember?

It is not my imagination. You are indeed more clever this year than you were last year.  |

Give up, Ernie. Just admit that IRS setups are a waste of money.  You will never, never change anyone's opinion. |

The true test of character is... how we behave when we don't know what to do.

I'll tell you what I know. Yes, not much.
But! I've been to several "Vette Magic" drag races and shows, both at the old Baylands in Fremont and Sacramento, its current location. I've seen plenty mid-year Vettes with IRS's: a) torque steer and b) blow up their open and posi rear ends. u-joints here there and everywhere.

Kevin,
If for no other reason, then resale value. The next guy will probably want the LSD. Eventually, you will either sell it and buy something else or sell it and buy a Cobra that's even "more better."
Now I'm kinda curious if my 328 with the Sport suspension has an LSD, though I haven't been able to break the tires loose yet in it. |

Actually there appears to be a healthy debate underway about how GOOD BDR's are with an open diff, on another thread. "Over there" I have followed my good mentors lead (thank you Pat) and am doing my best to confuse, thwart and baffle those who would dare oppose my view point.
The crux of the argument appears to be that an open diff is safer than an LSD, which is true of course. But then begs the question: You want "safe" and 500 plus horse power in a 90" wheel base car? OOKKKK then....  |

I've been following it. I think it's time to taunt him with a butt-salute.  |

OK, 92" then, dam, I've been tracked down and busted by "da man" even over here. Quick, where's Pat when you need him? |

The Lincoln Versailles had a 9 inch with disc brakes with a parking brake that rodders liked, but not a IRS--that was later with an 8.8

Naah, it's more like " a horse walks into a bar..." and the bartender says " why the long face?" |

No Ernie---but it does draw attention to the fact that 3" of travel with a solid axle car with 12" driveshaft has about same angular differance as an IRS rear with 3" of travel and 12 " half shafts
