Joel, please read my blog, it is specifically about people like you. Scroll up next to my avatar and you will see below "Feedback," it will say "Blog," click and read.
As a vendor, I will support another vendor and explain what you lack in financial knowledge. Keep in mind, I am not only selling parts here, I have a shop as well. Let's get started.
Here are lines what you, Joel, said in the post above...
"You're the designer and the fabricator and this is your show"
-Yes he is.
"A lot of win would be to just provide people with a bracket that works and let them source out their own calipers and rotors"
-Why not just make your own brackets? You see, I deal with a lot of guys like you. It is not easy going around and spending your time to make a kit that will only make you a little bit of money but supports the community. Steven and Albert have other things in their life they have to do. This was something they choose to do to help out us Supra owners and make some money. Albert sells turbos here if you haven't noticed.
Why would they spend all that time and make a bracket only to sell it and say, here is my hard work just go to the junk yard and get this and this and your kit is complete. You remind me of customers who come and tell me, "Yeah man, just do this and this" and have no clue how much work it takes to get it done and in this case, make a bracket. It's not just measuring the distance and drilling two holes, if it was, you should be able to do it.
If they were to do all this hard work and sell the brackets, I would list them at a super high price. Why? Because it allows you to use 17" rims, find another setup that allows that.
"I bought my rear brembos for $150 shipped with project mu pads and brembo original STI rotors for only $100shipped"
-O jeez. This is what I wrote a blog on SupraMania about last night. Let me explain, those parts are most likely all used and that person had no idea he was under selling himself. After finding a deal like that, you now think that is what the price should be for Brembo rears. Find out what they really go for on Evo forums and you will see. These parts Steven will be selling are new, not used and lastly, he is not a person who is in need of money to list them at below fair market value like that guy you bought your parts from
Anyways, best of luck and do as you wish.
-They will and it will sell.
