Wilwood brake fitment question (FD3S)
 

As I get going on my project here, I am considering installing Wilwood 6-piston front calipers (with larger rotors, of course). They put out two kits for the FD3, one with 12.88" rotors, one with 14". Of course, I'd prefer to go with the larger. One question is this: has anyone used these with the Enkei RPF1 18x9.5" +45, and were there any issues? I've had good luck with Wilwood products-that's my reason for going with that brand-but is that a mistake? Would I be better served with Stoptech or Brembo? Or should I just upgrade the stock rotors and pads to something like the DBA "Roo-Paw" rotors and EBS pads? Please let me know your thoughts. I'll mainly be using this on the street with a bit of track time and auto-x. Thanks in advance!

those are pretty good questions id like to know the answers to them as well.

Have you looked at this write up? For street use, pistons seals are an advantage.

Thanks-I looked, and based on what I read, I think I will look to a different manufacturer to fill my needs. I don't like the idea that there is caliper flex; along with the hat to rotor connection seeming to be flimsy, those are "fatal flaws" in my book. I appreciate the link to the review! So I'll stick with stock and go with Brembo or something when I can afford it.

Why do you think you need larger brakes? Are you warping rotors because of too much heat? doubtful with mainly street driving. For track and autocross, you don't want to add more weight, especially auto cross. The more weight you add, the slower you go so a 14"rotor would be dumb.

The 12.88" would be better but you have to ask yourself, do you really need it? What type of track days and How often will you be tracking, 3-4 times a year? How long are the sessions? Any less than 4 times a year and I would stay stock and add brake ducts.

Unless you just want bigass brakes to look cool, which I understand, it does look cool!

I came to the same questions....
 

....so Thank You! I don't need big brakes. Better rotors and pads, perhaps. Brakes have never been even the SLIGHTEST issue. Yes, the big rotors do look cool, but I have always been a "form follows function" guy....no reason to stop now. Thank you again for your input. Honestly, between the time I posted my question and you added your .02, I had come to the same revelation. I' m in the process of having a more powerful motor built, so my thoughts were to upgrade the brakes (like the Euros always do). But the stock brakes are fine-I'll just see what-if anything-I need to do after I get everything going again!

Type RZ brakes?
 

Another option might be an upgrade to the RZ brakes. If you search this forum, you will see a few threads on the subject. RZ fronts utilize larger calipers and allow you to run a larger rotor. RZ rears utilize the same rear caliper but use a bracket that allows you to run a larger rotor. The larger rotors will give you better stopping power and this setup also allows you to keep your emergency brake.
