    Worth money, great performance

    I installed the red ones, I must say I love the ride, it did stiffen up the rear in a great way. I did gain some NVH, when I have load on the differential I can hear the gear whine transfer to car. When I get off the gas the whine stops, it’s not loud but it is annoying to me, my wife doesn’t seem to hear it so that’s good. The performance upgrade was completely worthwhile and I recommend the upgrade. I only gave it 4 stars because of the whine.
