i have a 1999 z28 6speed mainly stock, if i get a camshaft, headers, race intake, that will give me about a estimate to 435 hp should i get a new rear end or rebuild mines? I really want to know need some good answers thanks ls1 tech

 

new, unless you like rebuilding a lot

 

dump clutch,get car towed home,rebuild
repeat as necessary !!!

 

you might get by on street tires. for a little while.

 

I would start saving for a new rear end a 12 bolt, 9 inch, or s60. My friend shattered his ring gear with a stock engine just launching it at the track.

 

I agree, you can get it rebuilt for cheaper than buying a new one but I'm sure it will just end up breaking once again at some point or another.

 

Autos can run them a lil harder,m6 cars just destroy them, i think 92% of tech members have broken there 10 bolts,

 

Thanks for the advice guys, i think I'm going to buy a new one then. Can't wait to finish my car got work to do

 

My car is down now cause I just fried my 10 bolt. Worst part is last year I just had all the bearing and **** replaced in it... what a waste of $. Do not drop a penny into the 10 bolt.... get a S60 or 9". They are expensive but its a must if you plan to race ur M6 on a tire.

 

^^^^ these definitely ... I pulled my 10-bolt before it broke and went spooled S60 and have not looked back. The 10-bolt is stored for a future demod.

 

what do mean "must if you plan to race ur M6 on a tire?"

 

any type of sticky tire ie. MT et street radial. im not 100% sure cuz i dont have an m6 but high rpm clutch dump+sticky tire+dead hook= 10 bolt destruction.

 

so then what tire do i use?

 

do not put money into the 10 bolt. ever. its ok to fix the pinion seal leaks. however...you need to call MWC a sponsor located on the right....and put down a downpayment, and over the next 3-4 months continue making payments, and when your almost done paying for it, they will be done custom dabbing it up, and when you get it you will never have to worry about the rear again. give it hell. its lighter than most 9's and just do a search and you will find nothing bad to be said about the MWC other than the fact that it takes some time to be built. good things come to those who wait though.

 

Thanks I'm considering in getting one just never heard of MWC?

Whats the price of a good one?

 

They start at 2700 with a spool and end when you wallet closes...keep in mind the next weakest thing is the ds.

 

Okay i don't mind paying thay much if its worth it and whats ds?

 

Driveshaft. Stock ones are typically aluminum and become the weak link with sticky tires and a strong trans and rear end.

 

To give a good idea with a PST DS & adding upgrades like posi, powdercoat, backbrace etc it was about 3500. A little more money than an S60 or standard 9 inch but it includes their chromoly torque arm & crossmember, their torque arm setup is hands down the best, its a very direct bolt in rear, options are unlimited & cheaper than Moser & IMO quality is as good if not better.

Definitely a must to upgrade it. I have seen some pics of broken stock ones & I feel really lucky mine never broke.

 

go 9 inches all the way... I'm going to be running a Moser 9'' spool rear.. the 10 bolt will last a little bit but you'll have to baby your car to not break it... and isn't the reason your modding the car to go fast?
