Thanks if u have an auto the 10 bolts seem to hold up fine but once you have a 402 with all the supporting N/a mods that u can pack in there and a Magnum t-56 its like Driving on eggshells i took it for a test drive the first day i put it all together 3 Years ago and then pop bam there went the stock 10 bolt. The older 70's 10 bolts are bigger( and with the right parts take countless ) made out of quality iron and now I wonder how it...

Ummmmm I realy don't think so... it has me at 3K at 70mph and I actually spin about 2100:screwy Use the second one on here where you can enter final drive ratio : http://www.ringpinion.com/Calc_RPM.aspx

my car kinda seems like it wants to be much faster than it is, but it just doesnt really have much after i hit 2nd gear. do 410's make it get off crazy, or do i need a 430, 456? its a m6, ls1.... when i drop the hammer, i want it to be scary ....what do u guys think?

saw someone post something about possible broken fingers on the pressure plate once. Jacking up the rear and starting the car and putting it in 3rd or 4th with the clutch all the way in and no parking brake and no foot brake, the tires should not move. If something in the clutch is not disengaging the clutch all the way the tires may rotate slow. This could help ID if it's trans or clutch system related

Hitting the underside is a common issue from what I gather. A lot of people have to "massage" the floor board to create clearance on tunnel mount TAs.

thanks that is what i was looking for.

The park brake cable is adjusted automatically by cycling the park brake lever three times. You may also need to adjust the PB shoe to drum clearance. You would need to remove the rear rotors and turn the adjusters to tighten up the clearance.

3.73s are generally what people put on A4s Thats what most recommend 3.90s would better be suited on an M6 along with 4.10s
