I have a 2007 Acura TL it is lowered on truhart coilovers and when I take a turn kinda hard it feels like it has body roll and the rear end is like kicking out on me does anyone know why this is happening and what I can do to fix it?

 

One of these sway bars would probably help, rather than the OEM one.

Did you get an alignment and what tyres are you using?

The description of the issue isn't making much sense...but...make sure basic things are taken care of.

 

How hard is "kinda hard?"

 

REAL hard.....

 

real soft.

considering OP had questions about brakes and control arms, his car is probably fucked up.

probably needs a lot of shit worked on....however, I've noticed OP will post a question then never return to answer.
so, we'll all have to assume his shit is super fucked up

 

Wonder is he has them dampened all the way soft?

Did the Truharts offer adjustable dampers?

 

My shits fucked up to, I know.

My guess is his car is probably a salvage title. Just sayin'...

 

Yeah id guess either the coilovers are worn out and/or crap or theres something else worn out. My 2005 stays pretty planted with over 200k on the original shocks. I could be off base as I dont have any experience with aftermarket coilovers but just generally speaking (and based on my experiences with other aftermarket parts) I find it hard to believe a decent set of coilovers can be made for $500ish.

 

I have a Progressive rear sway bar and I can take corners at a good clip and get very little to no body roll and the ass end doesnt want to kick out. Also have a good set of tires on the vehicle helps.

 

see, i told you OP wouldnt come back

 

Yes, you did. Think he rolled it over on one of those REAL HARD turns??
