Any down sides of going Borgeson vs Firm Feel?

If you are happy with OEM, you will be really happy with the Borgeson. I feel the Borgeson is much sharper on center and responds instantly. These characteristics make it feel like a modern car.

I have the Borgeson box in my Duster and I don't have any regrets. I bought it through @BergmanAutoCraft when he was running a special. It hasn't leaked. It steers fine. The steering is tighter than stock for sure. It's smaller and lighter than the original, but yes there is one point where you need to dimple the header on #3 or #5 cylinder (I forget which) right where it exits the head and turns down it contacts the top of the steering box.
