I believe at least some of them can be installed without removing the front bumper. I have the raceseng one, and you should be able to install by just removing the passenger faux-vent
As above, you will need an aftermarket tow hook to toe from the front. There is an OEM metal loop in the front, but it is very low and set back; there is no way to use it without destroying the bumper.
It isnt summer just yet, but I was able to complete 20 min sessions this past weekend without coolant temps ever exceeding 205 degrees. Admittedly, ambient temps were cool at around 60 degrees so this isn’t much of a test.
Adjust clutch pedal rod travel (free)
Change trans fluid ($30 or so for GM synchromesh)
RMM ($30 or so for an insert)
Depress clutch fully when shifting.
Done. Trans issues fixed for $60 and a few hours of labor (if you can do the wrenching yourself anyways)
Edit: Another free thing you...
Hondata’s basemaps are just fine for daily use. There are countless people on this very forum running them, some in excess of 10,000 miles.
Are they optimal? No. They are basemaps so there is a level of margin built in.
Lastly, they are fully editable. You are welcome to take any of there...
