I've got an 03 VIII with 98K on it. I put K-Sport coilovers last year in May, since then I've been hearing all sorts of noise from the front end. Everyone told me that the springs are making all that noise, the worst part is that whenever I take left turns at higher speed and the tarmac is a little bumpy it sounds awful! Last night I took the same turn as before and I heard the noise but the brake light came on while I was turning. As soon as I got the car straight the light went off! I looked under the car and around the suspension to see if any parts my rub when there's load on that corner but no luck so far. At first I thought it might be the swaybar hitting on the down pipe but there's no sign. I still can't figure this one out, maybe it's the ABS sensor that causes the brake light to come on???? If anyone has a clue about this please let me know.
Thanks.

 

maybe youre low on brake fluid and when you turn the brake fluid level gets lower than the sensor and makes the brake light come on
by brake light you mean the brake light on the dash right not the taillight
only reason i assume this is i have no idea how you could see the taillight brake light come on from in the driverr seat

 

holy mileage... did u adjust the springs correctly, its not recommeneded to go springs, coilovers ftw

 

Yes I'm talking about the brake light on the dash. The springs seem to be fine, I'm going to have the whole set-up checked by a suspension shop in Atlanta when I get back.
I'm driving the car from Atlanta to NY every month for work so I guess it's easy to get 98K in 3 years.

The brake light comes on when the fluid is low, the fact that is happens when you're turning (when cross weight is being applied and fluids are getting swished around) also leads me to believe your "problem" is there.

The suspension probably could use some fine-tuning no matter what it seems. You're already going to have a good suspension look it over so there's no sense in trying to diagnose it here. Good luck with everything.

 

just as i thought low brake fluid
also theres a post in the suspension section of people with coilovers complaing of a spring noise and no one can figure out with it is some say its a bearing in the top of the strut

 

Thanks for your input. I'll keep you updated on what the source of the problem is.

 

check the big nut on top that holds the camber plate to the shock. had this loosen up on me once and it made a really bad sound.

 

Thanks, I'll check it tomorrow morning.
