I have a friend whos in-laws are a brake manuf. and they asked if I would be willing to let them use my car as a prototype so they could do some test fits, etc....

What they are looking to do is produce a 6 piston big brake system for the LS....at this time I cant really say who the companies is but they have been around for a while.

should I be worried? Anything I should keep an eye out for? Any info would be great, never done anything like this before so I just wanted to be sure what I am getting myself into....

 

I don't think you have anything to worry about. If the company has a good reputation (which Im sure it does, since there really isn't much room for error in the brake manufacturing industry!) then you will be fine- heck I would be excited, your probably going to get a set of great brakes out of the deal for nothing, and your going to have an LS that is able to stop on a dime!

 

Just keep in mind that you're going to void your warranty obviously when it comes to any associated brake hardware/components from Lexus.
