My 1st 9 mods on the JL:
1. Bestop Sunrider for hardtop. It is awesome and worth every dime.
2. 35" tires. The fact that you can put 35" on a stock Rubicon is awesome!
3. Tazer JL. A must have to calibrate the speedometer and shift points with bigger tires + ability to shut off the auto...
It's night and day between the two. I have had my 2010 JK for 10 years now and my 2018 JL for two. Bother are fun but the JL is soo much more comfortable and solid to drive.
