Ive personally done every bit of work to this car, including an engine swap when the first one let go, if anyone has any questions about any of the products ive used feel free to ask!!

Race i had this weekend with a procharged 6th gen camaro SS! Unsure of camaros power level, only knew he was on 11 psi and spraying methanol

Holy shit you smoked him. Did he start in the wrong gear? With all that displacement and FI and meth I would be bullshit. Nice kill.

That was actually our 2nd run, first run i got him by more then that but he said he wasnt ready apparently, so we redid it again and he said he was spinning in this run, but it was a 60 roll so not sure how much weight that excuse can hold haha
M3 LSD and condor solid diff bushings installed today, still need a driveshaft so that will be ordered in the coming days, condor bushings fit great and installed easily, was able to pull them with ease using some pvc caps, threaded rod, washers, and some heat from my torch. excited to be able to put the power down soon and hopefully not bust anymore axles with the upgraded m3 axles as well

This weekend i plan on finishing up the rear end install, driveshaft should arrive in the mail friday, gonna be doing a fluid change on the rear diff with liqui moly as well and buttoning it back together. Also have a oil change and relocating my oil cooler to behind the kidney grill with a psp oil cooler! Core that i purchased from them was pretty good, one of the brackets was bent im guessing from shipping maybe but nothing bending it back didnt fix, time to see how a good lsd feels!

PSP oil cooler installed today, overall its okay. really need to supply some instructions as far as where they intended on this to mount, learned that if you have it to far forward the hood latch will scrape across the front of it, luckily it didnt damage anything functional just boogered up the coating. also please ignore the horribly cut core support up top, that was from awhile ago for something i was testing out and never got around to replacing. but eventually got it all adjusted right and sitting tight. looking forward to how this one reacts over my old mishimoto universal core, this one is twice the size
M3 lsd swap completed and I gotta say! I Love It! Gets great traction from a 40 roll on 25-26 psi now, tracks straight as an arrow and very confidence inspiring to run it. Gearing change is so miniscule from a 3.08 to a 3.15 I don't really notice the shorter gears, also now with the solid condor diff bushings i installed as well i get less shifter clunk, now onto some races tonight!!
