That should be a sticky, it really addresses all the issues people see.

The only thing I would say that i wish there was more info on was the bracket fab info. I know that some people get a stock A 4 shifter base and mod it to work with a aftermarket shifter.

As I am not a fab guy but knowing what needs to be done would be a giant leap.

drive ability shouldnt be bad at all, even with a decent stall, my buddy with a 800whp supra th400, had no complaints with his, but i would like to know first hand from u guys as well

i wish it would of been that simple i have a csr shield w/arp bolts so that made it more of a challenge for me. i put the second bolt on the driver side in before jacking the trans up i should of did that on the next one up too but had to use my telescopic magnet tool, put the head of the bolt to the magnet and pushed it up in there then tightned her up. thats the way it goes sometimes though
