We spent some time yesterday removing the TJ Unlimited's hardtop and replacing it with a softtop.
In my opinion, the softtop looks better on the TJ Unlimited. It definitely allows the LJ to perform better.
There's actually less wind noise with the softtop than the hardtop and the Jeep feels like it's gained ten more horsepower on the road.
The front and rearends are being built and suspension components are on their way. Look for more in 4Wheel Drive Magazine.
