Hi, last friday i went at the strip and my car told me he need some more stifness in the back...already got upr pro serie adjustable upper and lower control arm, but driver side lower get to the ground...the front bolt just snap and the 2 side shim are just not reusable....thinking about having a machinist made some other way bigger and conical shape this time, this was problem one, second one is my rear sway bar, it snap at the same time...thinking about upr anti roll bar....what are the rate on them? Single one is good to how much tork compare to the double? Don't want to install a kit like this twice since it's weld in a tight space of the car...
Thanks in advance for your input about your own experience and help!!!
edit: well apparently i'm not the only one that break those bolt loll upr already made a kit to up grade them to 1/2in grade 8 bolt with way stronger shim than the aluminum one that came in the pro serie kit
