There is a thread on IRS vs Live axle on Camaroz28.com asking why the IRS Ccobras suck.
I thought they did well in AI but don't really remember. Does anyone have info on the IRS Cobras vs solid axle? http://web.camaross.com/forums/showthread....583#post4517583 Evan |

There was a thread on CC a while back that someone was dropping hints that with some tweaking and testing the IRS was as fast as a solid axle in an AI car on a smooth track while the IRS was faster on a bumpy course.
You'll have to go digging for more info because I don't remember, but my guess would be that the Cobra IRS is too sloppy (rubber bushings/geometry) out of the box because it was designed for a street car to have good street manners. Oh, and the IRS is heavier overall then the solid axle but it has lower unsprung weight, FWIW. |

I think they added weight to the beam axle car for the test. I also forgot to mention that this test is probably 20 years old (IMG:http://www.frrax.com/rrforum/style_emoticons/default/rolleyes.gif) |
