Hey guys i just had a bearing failure and ate up my 4.30s. My qeustion is whos running 4.56s and which brand has the least noise and best quality. i ask this because i have had 2 sets of frpp 4.30s in the car and both whined a good bit and also had 4 people set them up. Also two of those guys have set up 20-25 sets of gears for me in the past up to 4.10s without any noise at all so id figure it not my install being the issue and i do realize the lower you go the more they'll have the tendency to be noisey, but have heard of really quite 4.30s before. lets see what you guys are runnning as far as 4.56s and you feelings about them
