I got the SPC front and rear kits installed last week. The ABS/Slip/VDC lights were tripped, so I asked my tech to fix the alignment of the sensors as per the suggestion in the THMotorsports thread. We went out for a drive and checked the MPH on all 4 corners by tapping into the ECU. The front right was off a little but we got it close enough so that the ABS/Slip/VDC lights would not trip.

I drove around all weekend and didn't really have any major issues until I started hearing a sound very similar to the ABS self test sound you hear right after starting the car and moving at about 5mph. I hear the sound most frequently slowing from 45 mph to a stop and I feel a little shudder in the brake pedal. I can't reproduce it every time but it occurs with some regularity and my wife noticed it too.

What is causing this? I need to have some ideas before I go see my tech tonight to get the rear toe bolts put in.

Thanks!

 

bump again

 

bump, plz help

 

wait, so, your suspension is to spec (all aligned to factory specs) but you're experiencing brake problems now... i can't come up with any explanation... subscribed for other members' feedback.

 

yeah everything is in spec except for my rear toe (-.37/-.38)

 

hm that toe looks a bit off. could be the cause, although i don't see how it could...

 

it's off because i'm waiting to get the toe bolts installed but i don't think it should be causing this problem. the jarring sound is coming from the front and i wonder if it has to do with the alignment of the abs sensors ?

 

did they reinstall the tires correctly. (fronts/backs?)

 

ah. yes. provided you're not staggered.

 

i'm staggered but i will check that. i'm pretty sure they just dropped the tires closest to the install points and put them back on

 

any help people? still totally stuck with this problem and i might have to hit up the dealership

 

i would check all wheel speed sensors and connectors just to make sure nothing is loose, these simple things can trigger your light

 

what's the size of your wheels and tires?

 

happened on my 19s and 17s. i just got the problem fixed on monday. took off the unnecessary SPC bracket and spacers. everything's dandy now.

 

great to hear! extra stuff is never good. /me unsubscribed.
