Unless you are paper thin or have a hyualic jack at home - it will be a pain.

Don't jack up unevenly - you will end up stuffing the mount and make an even chassis - that is the very last thing you want.

Some understrut bars utilize certain existing points on the suspension that would require re-alignment after installation. Using the Miata as an example again, the Cannon rear subframe brace is one such item. I don't know if these do, but it's something to consider for underbody braces in general in this case.

Several groups that organize track days (the better ones, IMO) require a thorough third-party inspection before each event, which requires the car to be put up on a rack to begin with. It wouldn't take much to put them during that inspection (but you'd have to find time to take them off afterwards, of course).

The other thing is that you (or someone else) will be all over a regularly tracked car both before and after a weekend, checking fluids, changing oil, bleeding brakes, checking suspension pieces, torqueing down bolts, and everything else anyway. Depending on your particular situation, you might find that it's not much more of an effort to put on or remove this or that brace.

Install Autoexe bars/braces requiring no drill, but need modification:
Front tower bar: plastic engine cover need cut off (autoexe said it on the web) a little bit.
Rear tower bar: If you have spare tire kit, it should be removed. no drill on the car but do
some holes on plastic cushing is required.
Front under brace: No drill require, it's easy if you can lift up the car. The loss of ground
clearance should be blamed on it.
Rear under brace: No drill require, but it's tough job because you have to remove the rear
shock. re-alignment is needed.
