Koni sport yellow struts
My 01' 330 Ci is at 129000 miles. I recently replaced the rear shocks because I got them new for a really great price. The rears are Koni sport yellow adjustable shocks. But now, I am feeling that the front struts are slowly going bad and can hear squeaking and clunking noise from time to time. I think that clunking noise is attributed to the worn control arm bushing, nevertheless, I am thinking about replacing the front strut shortly in the future.
I am curious as to what front strut I need to purchase. Is it recommended that I purchase the same brand struts as the rear shocks, Koni yellow sports? Or could I go for something more affordable for me, perhaps like Koni orange struts. I mainly drive in the city and I don't know if having Koni yellow all around would be too harsh.
Also, I have noticed that non of the sellers offer just front Koni yellow struts. Where would I be able to buy them separately, if keeping the whole suspension the same brand is a good idea. On that note, I am also interested in some gently used front struts if anyone has good parts.
Thanks in advance.
