Other than the already mentioned uses for me is mainly keeping RPMs uphill, the most common use on-road is when descending on icy roads going around corners you dont want the transmission to downshift it can cause a loss of traction in really icy conditions so I always use M while on a descent...
I like the bumper your rear is similar I went went the Evo instead - check the Rustys Rear Fascia cover kit I added it to mine and it is very nice. Just realized I need to update my rigs build page, will add a few better pics later
I would go with 37's if you are going to regear, you can drive with 4.10s but the gas mileage will take a hit, I drove all winter in 4H and was averaging about 12 mpg, by the end of summer I was averaging 15 so in 2h I probably get 18 or so on the highway. You didnt mention if its a MT is so I...
The only thing better would be to make the headlight able to switch to amber when it sensed there was fog, snow, or dust in the road (a switch would probably be just as cool) so then it would be the absolute safest possible light ever.
Nice that sounds like a really good setup actually - I was looking at something similar when driving on back roads, I have my LP4s on a Switch-Pros switch on the A pillar and its not easy to turn on-off on the road.
The question I have is your high beams turn on the LP4s and they are not street legal - do you turn off your high beams at the first sight of other headlights? Not very many winding roads were you live? How does that actually work while driving on the road (angry drivers flashing at you)?
I would recommend the Amber SAE fogs in the bumper, in the heavy snow or fog they work really well, the stock white fogs actually make it worse if there is snow/fog on the road. I also have LP4's on the bumper in Amber and they are awesome.
This is my first summer wheeling in CO, there was a guy in an older Rubicon with 31's and couldn't make it up the obstacle in the first pic, he said a few years ago he went right up but it has eroded a lot since then.
The only way you can get anything back is if you can prove they signed you up without your consent. It is illegal for any mechanic to install or fix anything on your car without your prior consent. If they did not then you will have a chance, you won't get the 120 back but the 186 maybe.
