Strengthening my IRS

so i have a 99 cobra and its got pretty much every bolt on possible except pullies for now. im about to put a 4.10 in it to liven it up a bit but i dont want to blow my irs setup. i was thinking bullitflow irs brace and front and rear bushings but i thought id take a few opinions from the pros. my questions are 1. are pulleys even worth getting? and 2. how much of a difference should i be seeing going from a 3.27 rear end to a 4.10. thanks guys!! btw heres a vid of it with the slp loudmouth 1's before i switched them out with magnaflows for the people who are wondering what loudmouths sound like. my hair is also alot shorter now hahaha

just a quick Q. Should i go with the big kit from The boogie racing company or Maximum Motorsports? i kinda like the MM products. ive heard alot of good things about them but you guys are the experts. whats your input on the 2 different companies

i did some research on the cost of having bushings installed and its about 800 dollars so i was wondering if its a bad idea to put the 4.10 gears in w/o a bushing kit and maybe just with an irs brace. atleast for a little while. i dont really launch the car so im not sure what i can do. i really want to get some AFS wheels for it but i dont think ill be able too with the bushing kit. whats your input on it guys?

thanks!

i guess what im trying to ask is do i really need bushings to put my 4.10 in and if i dont would i have to worry more about breaking IRS?
