beaks kit and the bsq kit dramatically reduce the risk of tearout. And if acura sells a car in the USA with a 22mm rear sway combined with sub-200lb/in springs, beleive me, snap oversteer is not an issue.
I have a 22mm rear bar, and 400lb rear springs, and can still control oversteer just fine. I consider the itr rear bar one of hte best bang/$ suspension modifications you can do.
