How to make the 10 Bolt Stronger?
Go for the 12bolt. I got mine after watching my brother trash his 10bolt 2 times to the tune of $800 each time. Ive never had any problems and I never worry about it. One thing I learned though is that once you do the 12bolt you basically have to do a bunch of other mods shortly after. You will have to do shocks because the heavier rear destroyed my stock shocks in about 10k miles. You will have to do adjustable LCAs to relocate the wheels closer to the front to keep the larger 12bolt housing from banging on the body underneath (especially if youre lowered). And most likely you will want to get a new driveshaft because the stock one will now be your weakest point in your drivetrain and once you get the 12bolt you will want to be launching on everyone you pull up next to

You ride it out as long as possible, meanwhile start putting a few $$ away each week. When you finally grenade the 10 bolt, break out your little piggy bank and start hunting for a 12 bolt or 9 inch. If anything, do a set of gears to have fun with in the meantime. But understand 100% that the 10 bolt is weak.
Some last longer than others. y2khawk's lasted 2 weeks. I installed 4.10s in my m6 and ran 200 passes before my torsen let loose. I installed 3.73s in a 550rwhp M6 formula and they have yet to give out. But that does not mean everyone is so lucky.
Don't be one of those guys who 'can't afford a 12 bolt' but instead rebuilds the 10 bolt three times, and could have just gotten a 12 bolt for that much money. No matter what you do you are always going to be limited in size. Something has to give.
Here is a sticky that will benefit you.
