trailing arm help

By blk92hb
- Wed Jul 14, 2010 9:00 pm #204644 ok i need some help from felow road racers and auto x driver or anyone that can help. let me fist give you my mods first then i will tell you what is happening.

mods
tein mono flex coilover with pillowball mounts and 14k/8k springs front/rear

front
es front lower control arm bushings
es swaybar endlinks
no name upper camber kit

rear
skunk2 rear camber kit

the car has been lowered about 1.5-1.75 inches. it had a full alignment and the rear passenger toe is out of wack its at 1.54 degrees in. the adjustment is all the way out and that is were it sits right now.

when i take a 90 degree left turn at speed limit or faster i get understeer. when i take a 90 degree right turn from a flat surface to a incline the passenger side rear tire sounds like its rubbing the fender well or lifting off of the ground and thats is not even at speed limit, i could be pulling in to a drive way.

i asked the guy that did the alignment if it could be the trailing arm bushings because they look a lil shot but he says that the arm could be bent.
so what i am asking is, is there a way the check the trailing are to see if it is bent and what i would need to correct the understeering

thanks for the help and sorry for the long page just need to give all of the info

If the arm isn't bent, it may be the subframe or point where the trailing arm mounts on the front.

all disc/drum trailing arms are the same tailing arms. (coupe/sedan/hatch)
