If you compare the NVH from the Whiteline to ours (which i have experience with both), there will be more NVH with ours, but like i said its more like the big bumps you feel more than the going down the road noise. Its really hard to explain the difference, but since the WL product uses urethane, which is compliant, and our uses a spherical bearing that doens't flex, there will be more. But in my opinion, the NVH noise isn't bad like a Tien coil over setup. Not saying that a Tien coilover setup is bad at all.
I hope you don't think i was being harsh back to you, i just don't want people to think the wrong thing about a good product.
