No, havent touched the strut towers yet. Would like to when i build the 3.0 stroker. And no, but i like to think i will be. Have to look into HD front diff internals and somehow figure out a superior tcase. The bmw tcase is amazing in theory, but its too easy to destroy imo.

what about the 600 hp iX, that tcaseis holding up fine...

No one makes this car anymore. The government won't allow them, normal people won't buy them. So it's up to us: the freaks, the weirdos, the informed. To buy them, to appreciate them, and most importantly, to drive them.Comment

Pretty sure that guy has gone through a couple though. That thing is beast. Mine went out when i twisted off my front driveshaft. As seen in the pic hahaComment

I'd still like to know how you broke that DS. it was the lengthened one right? I've beat the hell out of mine for the last 6 years, no issues.Comment

No, just shimmed a little over 1/4". Funny thing, i think that was an auto DS, its like 1/8" smaller OD than the manual one i replaced it with. i was mashing through some gravel and it transitioned into pavement and i didnt get off the throttle quick enough, as soon as the front wheels caught traction it ripped the nuts off the bolts (grade 10.9) of the guibo and once the front part of the shaft hit the ground it ripped it off by the splines and shot out behind me...not cool.Comment

all ix driveshafts are the same dating back to the first model in 1985, there's no such thing as an auto/manual driveshaft :)
I'm surprised the front diff didn't break. must have caught that just right!Comment

Hmmmm, this is strange. Ill go re measure. I may have taken the measurement at a place that was compromised by the break but after the incident i compared the 2 i had with some friends and as i remember they were different. Not to contest your body of knowledge, but im never surprised when i find odd discrepancies in bmw parts. Like the hand engraved 25 on my ix intermediate shaft. Any insight as to what that refers to? Could it refer to the displacement?Comment
-
dunno, could be some sort of manufacturing mark or something. I don't think it's too meaningful.
I've had 4-5 ix shafts and they were all the same, there is also only one part # for all ix's.Comment

The original ds was 1 3/8". I inadvertently put the smaller one (1 1/4") in when i did my first swap because the splines were in better condition. It was the one that got destroyed when the bolts or whatever failed.
Here are the pics of the measurements i just took.

I just measured the two I have on my shelf (definitely OEM BMW) and they were both 32mm in diameter exactlyComment

Which would be the smaller of the two sizes i have. The larger one was 35mm. That was the shaft that was in the car since day 1. This is kinda weird, i know for a fact based on receipt history that the 2 old men that owned the car before the guy i got it from never changed a thing, it was bone stock. Only maintenance items were addressed. The guy that had it before me told me about how you could shim the shaft to catch more meat on the splines but had never bothered touching the thing. Its not a euro ix cause its the 3.91 final drive, although the car was imported from germany. Pretty sure all ix's were, right? Theres always the possibility that it could have been replaced and the records are missing.Comment
