everything he said...and cheaper.
Also, you will have to have more anchor points w/ alum. it has a tendency to vibrate and be annoying.
but take the time to review the various threads. Both coro and alum. There really are some good ones.
THe key (in my opinion) is to get the car up (possibly rent a lift at a shop for an hour) and get a really good idea of mounting points and bracing. The when you buy your materials- over buy so you have enough to do the job. save your receipt and return the extra.
