i recently lowered my 03 sedan on tein coilovers, ever since the rear seems very swervy on the road and the other night when it was raining it was fishtailing bad. any ideas on what could be causing this?

 

check you're tires, and your alignment which may be way off after the drop. Also check your rear sway bar and make sure the bushings are all good and nothing is broken.

 

any time you change ride height, you need to get an alignment.

Your toe is probably off by a lot- get an alignment ASAP.

it will save your tires and be safer for your car.

 

^+1 toe being off will definately cause what you just described.

 

yup had the same issue when i put basics on my sedan till i hit up mach 3 for alignment.

 

wow all that from just having my alignment off. when i put the camber and toe arms on i made sure everything was as close as possible. as for tires they are old and need to be replaced that why i havent cared about getting it aligned as soon as it was done... thanks for the advice.

 

If your tires are worn out, that's a large portion of the problem, no grip during wet surfaces.

Camber is not a big deal, but the toe being off is. Get that taken care of and you're fine.

 

toe and tire.

take care of it before you hydronplane. Nothing to be taken lightly.

 

IMHO you should have taken care of the tires before lowering the car. ALl the money spent on suspension, brakes and HP is wasted if riding on crappy or worn tires...not to mention very dangerous.

It's like buying a blu-ray player and playing movies on a standard-def TV.

 

after 2 weeks your suppose to get an alignment! its like 40 bucks

 

Just get the car aligned. Tires could be very worn due to bad toe though. Eats through tires.

 

in addition to alignment (which may or may not be the solution), LSD or Quaife ATB and Rare JDM Rear Stabilizer bar will help keep you from getting squirrelly.

 

After lowering my car with sportlines, my rear tow was -7 out, best they could do with stock parts was -3. I still need toe bolts as my rear is acting the same way as yours.

 

is yours acting this way in just wet weather or dry too?

 

Pretty much only in wet/snow conditions but I occasionally notice it when doing the odd lane change or if the pavement is really uneven. I have rear arms and toe bolts on order which will correct this. Plus if your toe is out that much it will EAT your tires like crazy.
