Installed coilovers (Bc racing DS true coilover conversion) on to my RCF w/ ~20K miles.
Install was successful but I butchered the sway links boots, however they still tightened down.

The only sound I am getting is a clunking from the driver front (seems to emanate from closer to the middle than the outside of the vehicle)
I could make the sound by rocking the car back and forth with my hands, or by going over bumps.

Any idea what this could be?

I have read it is typical of coilovers to make a clunking sound. One of the downsides. I don't believe there is a fix for it.

 

had cks on my 17 and heard clunks in rear. everything was installed properly and we cldnt figure out what was up. ohlins (figs build) installed on the 21 and no clunks.

 

While its typical for coilovers to make clunking noises, I would not say its normal and there is "no fix for it". Have the following things checked: loose top hat bolts, make sure they were anti-seize was used and white lithium grease between the top part of the spring where it makes contact with the upper spring seat, and do the same with the lower part of the spring and the adjustment collar, check for excessive bearing play (vertical and horizontal). Good luck.

 

I have an ISF, with hks coils. I get the clunk noise from the rear when getting in and out of the car. I've had everything looked over by lexus and another shop, they said everything checked out.

 

Turns out the front sway link did infact come loose, causing play, and the noise. Tightened them back down now and the noise is gone, will be replacing front links to prevent further issues.

BC DS True Coilovers have proven to be very solid, great ride feel noise free now. We will see how long they last, (and through Canadian winters)

 

Check the locking rings on the dampers.

 

Hi! What spring rates do you have for your BCR DS Coilovers?

How stiff or soft are they?

How many clicks do you usually set it at?

Are you still hearing the clunking noise?
