That’s my biggest concern about tracking with a shorter ratio diff. Sure I buy myself the ability to keep from downshifting to 2nd, but if I’m now getting up to 5th I’m not gaining myself anything (4th to 2nd vs. 5th to 3rd).Quote:

I'm so damn tired of shifting though. I miss the driveability and highway manners of the 3.07
It was one of the bolts on the rear axle. Looked at it wrong with the e socket and it stripped.
If this car was a DD I might not have gone to the 3.64. Right now the local autocross course I almost never shift out of 2nd. But I am pretty high rpm. Thinking this will make me shift between 2 nd and third on the local courses.
If you look at gearing charts most of the dramatic change is 1-3.
I drove mine with 3.38 160 highway miles yesterday, and I'm loving it. Hovers about 3,200 at 80 mph, so there's more"hum", but I like it. Downshifting to 5th is seamless and only necessary for rather aggressive acceleration... I think I could stay in 6th from 40 to 160 (not that I ever do that). Is it "stop and go" that's tiring you out?Quote:

Ah, yeah. I had to sacrifice a small hex socket to one of those when we were pulling diffs in the junkyard. Just hammered it on and popped it off that way.Quote:

Since I had to cancel my track time at VIR this weekend (thanks a lot asshole who hit my car!) I’ll have to wait until November to assess it again when I hopefully attend the Porsche Club’s HPDE. If I do a diff change it’ll be a winter project.
Stealership was a bust. No go on the axle bolt.
Tried the junkyard but all automatic cars bolt is longer.
Not going to race with only 5/6 bolts in. Not worth the chance. Am driving it around though......
Damn I wish I read this earlier. I'm pretty sure I have a couple of spare axle bolts...
