Well, I have been a lurker on this thread for quite some time.
Some observations:
I am not convinced that this is an SPF or a Wilwood issue. Things just don't make sense. Whay are there not more people with major problems? Why are there people with absolutely no problems?
I do not have an answer. It could be an isolated SPF problem. It could be an isolated Wilwood problem. It could be an installer issue.
The one question I have is why the installer or dealer let a customer drive off with inferior brakes. If he did not know they were not adequate, why not? Isn't it reasonable to expect this kind of deficiency to be caught by the installer or dealer?
If anything, this thread has put more focus on taking delivery with appropriate braking systems. I know I have had extensive conversations with Wayne at Gear6 over this issue. He has actually posted a memo on this issue on his site at
www.gear6performance.com. It's worth a read.
