I am not sure, i have been looking at whiteline but i saw energy has them too for alittle cheaper.
It doesnt clunk at all normal driving, but when i launch it wheel hops like that sh!ts going out of style. I also had this horrible smell i couldnt figure out where it was. then i saw drips on my muffler pipe. then when i jacked up the car i saw it dripping from the rear bushing. Its black and fuggin nasty.
