:) Well it's not like ALL replicas are that "well designed". There is considerable variance between any given "kit car" manufacturer, home built, used vs new parts, taking measurements for that new drive shaft, jury rigged suspension mounting points, etc. There are even "home built" Shelby's and Kirkhams out there that might be suspect on some level. |

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

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.
Patrick, how much does that 2nd roll bar, all the duct tape and HVAC insulation add in weight?

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

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. |

Electrical tape? I always thought you used pipe insulating foam to protect your roll bars from freezing. :LOL: |

Cheap roll bar padding from Summit, and even cheaper electrical tape. So far, no freezing and no electrical shocks. And just to provide an additional laugh, I have been doing it exactly the same way for over three decades.:LOL: |

I neither inferred, implied nor said any such thing.
The available rear suspension travel in a live axle Cobra, with its inky-dinky driveshaft, is substantially less than that of a much larger (longer and taller) Mustang or Kay-maro with (among other things) a four-foot driveshaft.
I would assume that any "well designed" live-axle Cobra limits that travel to safe margins - no body or frame impact and not exceeding the safety angles of the driveshaft joints. |

I was told that Patrickt made his roll bars out of sch 40 PVC to keep his IRS from bottoming out!:JEKYLHYDE:LOL:

Jeez, this is where Chas. and I left it last night -- the length of a radius and the arc of the circle. Three inches of lift on the end of a four foot driveshaft is going to have a significantly smaller angle than three inches on a foot long driveshaft. Tell TB to get a broomstick and a ruler and he can prove it to himself.:rolleyes: |

You know, 94 posts ago I should have told charlandk that any noob that was advised to get a Roush and T-56 should have figured an LSD was needed to play the Cobra game. My bad.
For your complete edification charland, there are virtually zero Cobras, real or fake with open diffs. No sense trying to put down 300 to 700 HP in a 90" car without one, right buddy?:confused:
The post count meter was needlessly pegged on this one...:eek:

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. http://www.capitalareacobraclub.com/...ve1/10_6_8.gif |

A few years back at Carlisle, I saw an IRS setup that used a Ford 9" for the center section. The rest of the set up looked as beefy, too. I liked it. |
