Evening,looking for a diff brace for car,more track than everyday.getting a knock under heavy braking.Have ront and rear strut braces,but had some tution and it was suggested it could be the moving.Nothing obvious ever underneath after every trackday.All threads seem out of date to purchase one,any ideas for a purchase.Also I have standered ARBs,was thinking of chaning,but rather than spend a small fortune on the bars and bushes,I see powerflex do a black series of bushes which would stiffen and looks much more cost effective.Anyone this instead. Thanks for replies,if any
