My 2¢:
You run a genuine race car, with that much exposure. i would not use loctite on susp bolts. With such nice bolts you must certainly be using proper washers, lock washers and lock nuts as may be necessary. Perhaps you even use bolt stretch length to set the clamping forces, rather than torque. If so, just record and measure the bolt length to prove the force is with you. Easy and non-destructive.

If you try and retorque, you will not get a sensible reading until the loctite breaks and even then it will be grainey, perhaps.

i would regularly re-torque the bolts before each event and begin to document which are getting looser, if any. Take special care to check them very carefully. Some, even, will get tighter, though not often for no good reason. Make sure you are looking at the drive-line, transmission and linkage bolts, also. And don't forget engine mounts, both manifold sets, side-exhaust bits and the entire engine compartment. And your seat bolts, wind-wings (if any), fuel pump brackets, fuel tank brackets...

You get the idea.

F1 cars do not have loctite on their susp bolts.

On the other hand, some few insist on using it. If so, just test enough to ensure that the loctite hasn't loosened, not enough to test the actual bolt torque and crack the loctite joint. If you figure out how to do that, let me know.
