Upper/lower control arms.
 

I found a really good deal on some control arms through a friend of mine. Just wondering if I should go for them.

I know they help launches, but will I see any overall handling improvements?

Also, I heard that continual launching with control arms will wear on the frame. My car isn't that 'hardcore', but I do plan on getting a A-Trim at some point. Would this be an issue with me?

Should I go for them?!

Thanks,

I loved the change brought on by my lower control arms. The rear end seemed so much stiffer. I could corner much harder before the back end came loose. Not to mention they help w/ launching.

I'd get them. I've never heard anyone say they like the non-boxed, stock control arms better.
