mac rear cover vs t/a rear cover is there really a difference and do either of them really help? i have a chance to get either, and it looks like the mac is 129 with studs, and the t/a girdle is 154 + 24$ for the stud kit... so that is a big difference in price to me anyways, they look the same though. any feedback would be good.
just trying to strengthen the stock rear a lil, i have an auto so i think with a cover it will hold for a while.

My T/a cover didn't come with a magnet like the stock cover has. I don't know about the Mac. I have an M6 and I can say that the rear has been hurt. I doubt the cover could have done much anyway since cap movement most likely has nothing to do with whats wrong. My $.02 with 2 cents change.

The T/A, MAC, and G2 covers will all do the same job. If you look at shots of them, you'll see that all three are almost identical stucture-wise. Don't blow more than you have to...

with a stock rear end, minus an eaton differntial, i only tried launching at 4000 1 time on a well preped track (m6 btw) on bfg's and it shearded my drivers side axle and exploded the eaton diff into 1000's of pieces, since then, i put on the ta cover from thunder racing with the stud kit, and decided to launch at 3600, it held, i bogged, i tried 3800, it bogged, then i tried 4000 rpm launch, and it did pretty good, 1.75 60' then i got even braver and launched at 4200 and pulled a 1.69 60'! i have to say, im either very very lucky, or that ta girdle really really works!

I have the MAC girdle. The casting appears stout. I was not
impressed with the quality of the tapped holes (drain plugs,
preload studs) - very rough and have to be careful not to
cross-thread. But it doesn't leak, and lets you change the
juice when you should, and I figure if you're investing in the
10-bolt's guts you might as well cap it off solid.

I've had the MAC girdle for a couple years and have put well over 100 track passes on it with different tires from Nittos, ET Streets and MT DR's and no problems.

Curious, do any of the aftermarket covers have the magnet installed? My T/A didn't. 
When I took the stock cover off it had a very fine coating of metal powder stuck to it. When I realized the cover I was putting on didn't have the magnet, I actually thought twice before I bolted 'er up. Does any one know of there's an easy way retro fit a magnet to the inside of a T/a? I thought about drilling and tapping-then putting in a magnet that I had threaded the outside with using a die, but.... o well.

The magnet is not an issue....The covers and studbolt kits are for strengthening the rear just a bit. Change your gear oil once a yr. and don't worry about a magnet..... WJ
