I am going to throw this one out there....

I had the stereo off today driving with all windows down. I swear I head this noise you speak of?? I sounded like I had a basketball in the trunk and when I stopped it had hit the area in the trunk that separates the back seat.

Does this make sense?? I looked in the trunk to make sure I had nothing loose in there?? I dont know what it was and if its related to what you are hearing Vik??

A basketball in the trunk is an interesting description My noise does not happen when I stop. Only over bumps. Honestly though I can't really hear it and I hope I don't scare off potential F-Sport buyers.

I'm starting to hear the noise now but it's not so much a clunk but a clanking metallic noise. I hear it when I go over some sharp smaller bumps at a moderate speed but not so much big bumps in slower speeds.

Doh! I'm starting to hear a sound when I go over speed bumps at about 5 mph. Sounds like golf clubs clanking in the trunk to me. Doesn't really bother me since I don't really go over many speed bumps.

What Mike meant was that the sound is similar to "something tossing in your trunk and hits the metal backing of the back seat when you stop" type of sound.

And Mike, that is exactly the sound I turn my stereo up high to hid all the rattles and clunking lol

Had the lexus dealership check my suspension during my 5k service, they said they didn't hear a noise and with visual inspection they said everything looks good.

Wow.. All these descriptions still lead me to believe the possibilty of the Parking Brake Pedal adjustment issue...

See my Post# 13 in this thread..

If any of you bring it to the dealership, HAVE them properly adjust the P-Brake Cable during the tech inspection.
The rear wheels will have to come off... and maybe the rear rotors too...

It really sounds like the slack in the P-brake cable is the culprit..
But thats just my opinion.. based on the inconstancies I have read in this thread..

If anyone in SoCal wants ME to diagnose the noise, just shoot me a PM.. I can replicate the noise with the P-Brake issue and I know how to test the P-Brake while the car is in motion to see if the noise disappears..

This thread is making me hesitant to purchase the springs, however I do use the P-Brake regularly so I may not experience the noise...

there is a tsib out for this problem. just ran into it. but i wonder would they fix this issue knowing you lowered your car...

"Some 2006 – 2008 model year GS/IS customers may complain of a rattle noise coming from the rear
of the vehicle when driving over bumps. If this condition occurs, adjust the parking brake cables to
reduce the parking brake shoe free play."

^^ You don't need the TSIB, if you tell them that you need your P-Brake cable adjusted..

I am telling you guys to just try & bury your Parking Brake Pedal for long periods of time for just a few days... It will fade away..

This thread helped out member "fishnfool " with the same exact clank/rattle problem on his brand new 2008...

He read my posts in here and it solved his rattle.. He was also dropped on Tein S-tech springs.. which have that protective wrap between the spring coils.. (so he knew it wasn't spring related)
