What exactly are you replacing in suspension. For shock absorbers, non oem ones simply dont match the ride quality of oems, and are a regret after installing (kyb is good alternative but it doesnt dampen like oem and makes ride stiffer).
For bushings, yes you can go for RBI (verify that you get genuine ones- mostly fake ones in market). Contact bush and mount co., I have had good experience with them and their products seem genuine (sometimes expensive than market). When installing, double check orientation.
For ball joints, 555 is a good alternative to oem (japan ones, there are probably malaysia/thailand ones available aswell, dont know how good those are). Have it in multiple cars, they perform just like oem.
