10 bolt to 8.8 I’ve got a 8.8 laying around and was fixing to get a shop close to me to cut the tubes off a 10 bolt and weld it to the 8.8 for my 98 z28. Are there any downsides to using the 10 bolt tubes as opposed to just using the 8.8 tubes? Also is there a preferred rearend? I have one out of a explorer, but can change if necessary. Thanks for the help

can’t be much worse than what’s in it lol. I believe it will hold up to a fair amount of power still. What would you recommend?

700hp + manual trans + torque arm won't be a problem, not even with if traction + hi-rpm launches are added to the mix. The real problem comes when a clutch that hits way too hard is installed, which will force you to overbuild the rest of the drivetrain, make your car hard to launch, and generally slow the car down. Just choose a clutch that matches the power you have.

Honestly the 8.8 is a very poor choice for a 700 hp M6 fbody. Don't just take my word for it. Call all the big rear end companies that deal with these cars and they will let you know. Honestly I'd do either a 9 inch or S60. Believe me I'm all about saving some money and would love to do a nice 8.8 rear, but i've done tons of research on this, and talked to several manufactures, and realized this would not be a good investment for the long term

Big companies don't do torque arm 8.8's, so don't expect any endorsements from them.
From a manufacturing standpoint, a torque arm 8.8 just doesn't make sense when you must source used parts in volume, then put in the labor trying to make them look like they are worth as much as new parts. Crooked tubes to straighten, oem weld undercuts to fill in, rusty tubes to rehab, it all adds up. In the end for a big company that has to compete in the marketplace, new dedicated parts are less expensive and more attractive to the consumer.
I'm not a big company, but I have personally fab'd hundreds of my own version of torque arm 8.8's so I can speak from experience. My personal car has had a torque arm 8.5 10 bolt for over 15 years now, it's well north of 700.

It’s mostly a street car with the occasional track outings, so won’t be seeing spray or hard launches often. I would say n/a the car is making 470ish? Where do you think the weak point would be in the 8.8? And with it being mostly street driven do you think the parasticic loss of a s60 would be worth it?
