Are there any benefits over a functioning system?

dam rite there is I hate hicas and have removed it I found it made the car some time kick out in the rear and it was always on my mind when driving it its ok if your just cruzing round and don't drive it like you stole it but for us that do drive a little harder than most getting rid was the best move it wasn't for me am sure some people will tell you they think its great but I didn't like it atall made the car feel odd to me

I've never had an issue with it, except when my inner tie rods were worn. Once I replaced them, it was fine again. I drive it quick sometimes and find that the car is really predictable when the back end lets go.

fixed rear wheels are miles more predictable for sure
