Put her up in the air today to check out underneath health...........been a little past 1 yr since the last time I had her on stands\ramps.........all checked out good but found 1 of my exhaust hangers had broken off since (had been recently noticing a random, weird, sudden & out of place KS voltage ramp would show up on datalogs from time to time......mostly on B1--the side I found the broken exhaust hanger.....didn't affect anything.....just looked weird......broke from constant exhaust heat cycling\vibration over time.....) from its crossmember mounting bracket, so I pulled it off the midpipe to stop it from rattling against the crossmember. Already have a set of SS clamp-on exhaust hangers to replace these so I'll plan on doing this work in near future (I know these aren't really necessary, but I want them.............) ........most likely after I get my 2 G-Sport\GESI GenII Advanced #24531 Hi Flow 500-850 HP LEV II\LEV III 400 cell EPA-cert cats installed.
While I had her up, I also replaced the fuel filter (had initially replaced this in 1-2018 shortly after I had bought her, thus filter had been in service for 8 yrs......), 8 yr old filter showed to be clean when back flushed thus really didn't need to be changed out but did it anyway. While removing the plastic cover to access the filter, ended up twisting off both studs due to rust--even after using WD-40 & slowly trying to work the nuts back & forth, so after filter changeout & passing leak test I got out my trusty die grinder & cut the 2 stubs off flush to underbody then center marked & drilled 2 holes to install 2 M6 rivnuts in their place & replaced the broken studs w\ 2 M6 x 20mm bolts w\ anti-seize on them to arrest\slow any future thread rusting (had driven car a couple of times datalogging during winter 2022\2023 right after snow clearing up a certain hill in my datalog route that had gotten salted but not fully dried.......most likely where these 2 studs got corroded.....the other 2 original M6 x 20mm cover bolts came right out w\ clean threads......screwed into unibody channel thus were shielded from the salt splash\spray).
Put used fuel filter back in box after allowing it to completely dry out to have on hand as a future spare filter........but from my observations it'll be a LONG time before this will need to be done again................that is, if I can manage to always use stations that have high premium fuel turnover thus clean fuel in clean fuel storage tanks.
So far, so good..............
Will run a datalog soon just to capture the data for records to then compare to previous data to see if I can spot anything notably changed\changing since this filter changeout.
Also noted that both rear tire's tread wear has reached the wear bars thus will need to get replaced shortly (mostly from making a LOT of 2,500-6,000+ RPM 1\4 mi WOT hits while datalogging after a tune reflash........the 1-2 & 2-3 shifts are where the rear tires will momentarily break traction on the initial post shift full WOT hit.......1-2 shift is by far the hardest on them........they've been on the car since 4-2019, started self-tuning in 3-2022 but started really getting after it after I got my OBDII Relocation Harness installed in 12-2022 to facilitate datalogging while driving thus the start of datalogging WOT hits.
Gonna stick w\ the trusty Continental Extreme Contact DWS06 series all-weather (DWS = dry, wet, snow) hybrid performance compound tires (fronts are approx 1 1\2 yrs old--replaced due to abnormal inner shoulder tire wear from worn inner tie rods & wheel hub bearings thus only need rear tires........).
