Who checks suspension/caliper TQ before a track event?

people that track multiple times a year may want to do this. You may be surprised at want you may find.
For example I have found TQ differences on the caliper sliding pins--it did affect braking, found sway bars that were binding due to overtightening, e links bound due to needing fresh grease, end links a little loose, etc, etc.

^ Good advice...you are right about accumulating little problems. Time and wear have a way with mechanical things, that's a guarantee.
What did I find? I changed brake rotors/pads/painted calipers this spring and found:
...noticed beveled pad wear, making caliper piston tilted in bore, 1st attributed it to beveled rotor wear, but after disassembly found true cause as sticking caliper slider bolts binding and resitricking free caliper movement, thereby binding up everything. Yikes!...really glad I did the teardown.
Moral of story: finding a very very small worm hole in your wooden house more than likely means that your house foundation may consist mostly of sawdust. So do a once over teardown of any parts subject to binding each off-track season or suffer the possible consequences and related expenses.

I do a full nut and bolt check on my car at the beginning of the season and hit everything with a paint marker as I go over it. Now it just takes a look to see if anything is moving or loosening up.

Second the Spring nut-n-bolt session. I'll stick a wrench on the trouble spots again before a full weekend (anti-sway links, exhaust bolts, etc) and on anything I've been messing with. Haven't found anything get loose except anti-sway motherf$*%^&ing end links. Paint marker is a good idea.

I have the urge at times to want to over TQ certain bolts justifying it by "I am tracking and there is more stress involved". So wrong. Especially on the brake calipers.
I have found a better substitute for the little rubber grommets on the end of the caliper sliding pins. I tried to buy new--to find out I had to buy the entire pin. SO I just used the correct size shrink wrap---worked like a charm. Be sure to use ceramic grease.
