Lots of aftermarket gear and carrier selections for the 8.8" and its more than strong enough for any amount of power u can possibly put to the pavement in a road racing setup!

Because the IRS one can't handle the power without serious upgrades and even then. All the info you care to read https://www.svtperformance.com/forums/threads/the-irs-tech-article.213384/ They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

There isnt any issues with that, all the problems the cobra guys had dont pertain to my setup. Solid mounted 8.8", in a full tube chassis with custom control arms mounted with spherical bearing ends & heim ends, custom spindles, penske shocks, splined sway bars, oil cooler, etc... What I was meaning was the 8.8" ring and pinion itself is a very stout design. All the rubber and flex that was in the stock cobras was half their issues. Also IRS will never be as effective in drag racing environments where alot of issues arise too. My setup is for road racing...no straight line crap, hence why were in corners are best forums!
