Dont have the money for the s60 right now and dont feel like throwing extra money at something im not going to keep. The eaton did hold up to 30k miles and over 50 track passes when I had it and I bought it used.

But how many of those track passes did u actually 60' really hard? That is what will kill the eaton. Lanchin hard on sticky tires will kill it real fast. You could just upgrade your axles and throw in a locker or spool and be done. 12 bolts are pretty strong when done up right. And s60's weigh so friggin much.....you could pick up a used 9" cheaper and its def lighter.

Just my .02........i speak from experiance.....not opinion

Im not going to be racing on it, dont want it to start whining again after a few launches. For the price of a used 9in I can get a new s60....Ill be looking at both when I go to buy tho.

if ya got a 9" can't you have a few center sections so you can run a spool at the track and then a real dif for the street miles where you have logged over 30,000 miles? I always thought that flexibility was the cool factor with a 9"

the s60's ring gear is 3/4" bigger than a 9"....please explain to me how a 9" is stronger? The s60 weighs all of 20lbs more than a 9". That difference is next to miniscule. If youre that worried about 20 pound go on a diet.

When u start goin fast that 20 lbs will make a big difference and a fabricated rear such as the fab 9 or m9 is stronger then the s60 with less drivetrain loss

3/4" bigger in diameter but the toe to heel thickness of the gear is smaller. Dana loses in that case.

This, you can't go making tight corners. I upgraded my studs to arp and never had a problem. I also never broke a rear... Your not trying to make it handle, spool it and be done

I suspect the spool supporters are not putting 5,000+ miles a year on the car. The more you drive it the more of a chance you are taking. Fine for a race car, asking for trouble with every additional street mile. ARP studs do not remove all risk.

Can you show any documented proof or examples of the idea you are proposing about spools and street use?

I can't add to my last answer (edit, yes I can, it can cause tire wear issues too). People are allowed to do as they please.

This is one of the topics that the "for" people will defend to the hilt and the "against" people will stay in their corner and no amount of added information changes anyone's mind. It's one of those "if I didn't see it happen it's BS". Ok. To each their own.

I am merely curious about where the internet fallacy comes from. It seems there is always someone who says it will cause the end of the world and someone who says they daily it 10k miles a year with 5 parallel parking jobs a day.

So, a example of why it is so bad would be nice here.
