I understand these springs come with Titanium retainers. So the bottom line is that if you want a MMR spring upgrade for the GT-500 heads, the only option is $850. Not everybody needs or wants Titanium retainers so why not offer springs at a decent price with steel retainers? MMR doesn’t force people to buy Titanium retainers with the springs for the other 4V heads. Why should these be any different?
This is simply a matched kit and unfortunately the only way we currently sell it, we certainly appreciate the input however and will consider a budget kit.
