Rear sway bar and oil changes
The aftermarket sway bar holes are way off what the OEM endlink is designed for, and I'd have to severely load up the endlink in order for it to just fit. I obviously didn't like the idea, and ordered whiteline end links for $114 shipped; not bad. They arrived today!
The adjustable whitelines are about same weight as OEM; 1.8 lb vs 1.7 lb.
Whiteline end links allow you to offset the link to the left, center, or right; great! Even so, Perrin's third (softest) hole was way off the endlink. I'd have to far extend the endlink to make it not pre-loaded, which would like be beyond its intended adjustment range. Alas, I've decided to use the second hole on the bar.
With endlink offset right most, the mid hole aligns nicely.
I was feeling a bit of resistance in T2 over the weekend. The rear sway bar should also help with this a little bit, but we'll see. If I still have this issue, I might consider upping the spring rates from 450/550 to 500/600 or 550/650 lb/in.
The differential fluid was very stinky, and the plug had so much stuff on it. It was so stinky that my wife asked me to open garage doors since it "stinks the house".
It was pretty hardened sludge. I'm thinking about replacing diff fluid again in a short interval for cleaning up the rest of the sludge that I probably couldn't remove. I've used Amsoil 75W-110 Severe gear LSD, which should also work better in high temps.
I did a quick test drive, and everything feels fine for street : )
Also sent the oil for analysis to Blackstone; we'll see what they have to say.
Looking forward to the next opportunity to test it out at the track..
