Not trying to burst your bubble or be a d**k but.....Heating the springs to lower them further is a huge NO NO. You might as well throw them away after heating them or better yet, don't do it at all. Even if you can get them to drop evenly you won't like it and it's dangerous. You've messed with the temper on the steel and they will be softer than your stockers and prone to breakage due to heat stress. Doesn't matter because you won't be able to fit those wheels at that much drop anyways, can't be done unless your willing to do a lot of cutting and hacking. Don't say you'll roll the fenders, because on the rears you can't because of the door frame. At most if you do a little trimming and hammering you can gain 3/8". There isn't much out there for aftermarket Poly bushings for the LS. Swaybar mounts are about it. Carbon Fiber Driveshaft? What on earth for? The miniscule performance gains are no way worth buying a custom driveshaft that is worth more than half of what your car is. Lastly, even if you did do an LSD swap the V6 doesn't make near enough power even with an Exhaust, CAI and SCT to realisticly drift except on wet pavement. Especially if you want to run big rubber. Besides that where are you going to be drifting anyways? If it's on the street please tell me where you live so I can make sure to avoid that area at all costs.
We need to start a "Fast and Furious" Counseling and Treatment Center.
Do yourself a favor. Sell your LS, take that and all the money you were planning on spending on your upgrades and buy something like an older Mustang. You'll have a much more suitable platform that won't bankrupt you trying to make it work. If you plan on drifting on the street, then please buy a bicycle and get profesional help for everyones sake.
