Finally done some minor things to the Bullitt. Just changed the transmission fluid to Motul DCTF. Need either a 5/16 or 8mm allen key and possibly a socket to change fluid. Need the key for fill plug due to lack of clearance; could use either for drain.

While I was under there I went ahead and wrapped the exhaust where it runs by differential. See if this will have any effect on temps.

Don't have another HPDE until September, so will have to wait until then to see if any good effects, now that I've found the diff temp gaugeo_O

The wrap will help however, even when temps were in the 70s here in metro Chicago my cooler kicked in at around 165 - 170.

BTW the track package GT-350s come with both diff and trans coolers.

Ford is facing a class action lawsuit from GT-350 owners over this issue as the cars are essentially advertised as track ready and the base cars and the tech package cars aren't equipped with the coolers which are needed for long track sessions.

I'll be interested to learn how your HPDE goes in September. Where will that be held?

Those and the new Mach 1. Home track is Virginia International Raceway. I live about an hour from there. Will be reporting on this one because my son will be going with me to do his first HPDE

A bit of an update but no pictures. Got a track event this weekend at Carolina Motorsports Park and will be sharing the car with my son. Bled the brakes with Motul RBF 600. Installed new G-Loc R18/R12 pads. Found out one of my SVE wheels was cracked and I knew another one was no longer quite round, so I bought a set of Apex SM-10's, 19X11.5, from member ChipG. Mounted a set of 305-30/19 SC3R's on them. Hopefully since I will be on some relatively new pavement here and brand new pavement at Roebling Road the end of July, I'll be able to get quite a few laps out of them

Track wheels do age and some are inherently stronger than others. Good reason to patronize the site sponsors on here as the Apex or Forgeline wheels have stellar reps from track guys! Just commenting as I have seen cracked wheels over the years that were not the result of agricultural racing or contact, just they could not take the rigors of road racing or they were quite old and had seen plenty of usage.

There was no impact mark where the crack was. Wheels were about two years old. I'm pretty notorious for using curbing, so I'm sure that didn't help.
Yes, using OPM 35mm spacers
