Update time!
Alcon BBK installed, SPL front upgrade arms installed, Corner Balanced and Alignment, brake flush Motul 660...
car handles absolutely like how I imagined, the front end is way more responsive now, especially on the 265/35/18 140TW Gredge 07RS.
Brakes
the Alcon BBK is super light, brake feel is consistent. albeit its only been tested on my local mountain road... ACH, I generally have a lot more confidence to push a little harder than usual due to the brakes~
with the combination of the Carbotech XP12 front pads and XP10 rear pads, the bias has been good. still can't confirm this till the next track day. but so far it's been a pretty good street/canyon compromise. I do have XP20s that I will swap out at the track.
Suspension
the SPL upgraded arms up front have helped so much with bump steer which ACH was a good testing bed for as, that road itself is pretty bumpy in certain areas...I couldn't squeeze the -3.5 Camber I was aiming for, I might need to get new Camber Plates as apparently someone had stripped one of the bolts from the top hat from my previous alignment. f**** you 714 tires. But managed to at least get -3+ by adjusting it from the bottom.
so I will be ordering some new camber/caster plates from Ground Control, so I can squeeze more camber and more caster.
the current alignment is set up for Buttonwillow mainly but should be good at all my local tracks here, outside of maybe Streets of Willow and Horse Theif mile. which are more short technical tracks.
if you have any suggestions please let me know.
*ISSUE*
I basically threw a Bank 2 pre-cat O2 sensor fault, which caused cyl 1 and 3 to misfire and basically go limp.
the o2 sensor code doesn't show on protools anymore, but I originally pulled it when I got off the freeway. I think the sensor finally died. even my mechanic confirmed my o2 sensor was dying a couple of days ago on the bmw software.
codes:
- DME/DDE [MSS60] | 2B35: Misfire with cutoff, cyl. 1
DME/DDE [MSS60] | 2B37: Misfire with cutoff, cyl. 3
DME/DDE [MSS60] | 2B41: Misfire with cutout, several cylinders
DME/DDE [MSS60] | 2B57: No description found
DME/DDE [MSS60] | 2796: No description found
I also have some used low-mileage spare spark plugs I will test, but I had this pre-cat O2 sensor issue for the last half of the year. The O2 sensor should be arriving today. if anyone needs to replace the pre-cat O2 sensor it is PN:
might be time for new spark plugs it has been over a year since...
but the car could use a full maintenance package, which I will do prior to the upcoming track season. this is my daily car too as well.
anyways here are some pics of the BBK installed and a small video for your viewing pleasure.
