anytime i go WOT. it happens. but i checked the endlinks and one of the bolts i can spin, even though its tight, the other 3 i cant. my friend thinks it's that because its only one pop. and when i hit the gas it pops as the front end drops back down and the weight shifts back to the front, which could explain why it's only one pop, and only in lower gears. i plan on picking up a better set of endlinks than what i have now and seeing if that fixes the issue. im gonna pick that up with my tax refund. should be in the next week or two.
