Does anyone have 4.56's in a near stock 99+ Cobra? Just curious how the IRS would react. And how it would react w/ Raxles in the IRS? I am still working on getting a 99 Cobra and thinking of keeping the IRS if I could get it strong enough to handle everything but hard launches. I think I could keep myself from trying a 5K RMP launch if it will hold up to everything else.
