So I went to pick my up rotors today.. and to my surprised... the weight of the rotors in my trunk actually reduced the clunking noise from the coils .. and also made the car feel alot more planted... does this mean my preload is off?

^Sounds like something is definitely off. Definitely look at re-setting the rear pre-load. According to BCR, hand-tighten lower collar until spring is tight against the upper mount. Then add an additional 2-3 widths of the spanner wrench.

GL!

I had two sets of BC coils with different spring rates. Do you reseach. Lower spring rates on the BC's are usually the culprit, ie 10/8. 13/11 did the trick for me.

BCR send you new struts under warranty"?

12/8 springs here...no noises whatsoever. I still think it's a preload/setup related issue.

Yep, took a little effort to get them to send it, but they did. Now clunking noise is gone

^I wish someone could post a video of said "clunk".

Had mine installed a week ago and no clunking at all. The shop I go to said that it is probably the sway bar bushings. He put a load on it before he tightened everything up.

When you say "extreme drop ", do you mean coilovers? And when you say "normal shock", do you mean for example a F-sport shock w/ F-sport lowering spring setup? To get you to your goal, your best bet is a coilover setup, so that you can dial-in the desired ride height and adjust the dampening for ride comfort.

You cannot go wrong with the BR Racing setup; just remember to get the rear extended adjusters with the set as well.

the nornal shock coz there s an option if i want the extreme drop "shock"... btw, is it better to get the BC instead of Stance? do you guys know any site where i can get coil overs?? Tnx!

- about the rear extended adjusters, what's that for? and is it still okay if im not gonna get it or if im just gnna get it later? tnx bro!
