ls1 brake upgrade for 3rd gen

i'm looking into this upgrade

http://www.bigbrakeupgrade.com

and i hear that i can do this for alot cheaper by getting y own rotors and calipers elsewhere, shaving down the stock rotors down to the hubs getting longer wheel studs and buying the bracket, and modifying my spindle

now here is my question
should i try and modify my spindles myself
should i send this guy my spindles to be modified for $75 or
should i buy the spindles with the brakets for an extra 70 bucks

now i can gain access to a jigsaw or something and butcher the spindles myself
i'm just not sure where to stop cutting and then what can i use to drill the holes andhow can i be sure of the position of the holes? i have yet to see a template
the car is off the road so i can afford to send my spindles away for a week or two

or should i just shell out the extra 70 and buy new spindles, and then maybe sell my spindles on ebay to make back a lil money

does anyone have an opinion on the subject?

i'm only asking how difficult it would be to do the work myself
or should i just pay the guy to do it?

The spindle mod is easy. id say pick up a spaid set and do them. Just incase you mess up.

The bracket and hub would be harder for someone that doesnt have a cnc/mill/lathe.

Where are you located?

I could do all of the above for you if needed.
