Wilwood Forged Dynapro 6 Big Brake Front Brake Kit (what's on whoosh) vs Forged Dynalite Big Brake Front Brake Kit

[esp_martin]

Can anyone explain to these wheel clearance guides?

Wilwood Forged Dynapro 6 Big Brake Front Brake Kit (what's on whoosh)



vs


Forged Dynalite Big Brake Front Brake Kit



the top is the 6 piston BBK that you can find on the whoosh site. however most everyone has wheel clearance issues with that build. the bottom is a the 4 piston kit that Wilwood markets/fits to 90s era Civics/Integras. The eye test says the 4 piston would have better wheel clearance but it seems like on the sheets provided that's not the case? if anyone could better explain the above clearance guides I'd really appreciate it. I've already reached out to Wilwood to see if they could make the Forged Dynalite fit the Fiesta. Has anyone else talked about this before? What little I could find on the forum didn't really mention much about people going this route.

It would probably help if you knew that Wilwood doesn't make a brake kit for the Fiesta ST
The front and rear options are Base model kits, designed before an ST was available so any clearance questions you have related to the ST and it's wheels won't make sense

I installed the Wilwood brakes that Whoosh sells and if you are wondering what wheels they will fit. I used my OEM alloys and they fit.

Did they fit without any spacer or mod on the hub? Do you have pictures for reference?

l used a 3mm spacer to get the clearance that I was comfortable with.

You did front and rears? With Stock wheels and no spacers? And they fit with with no rubbing?

I had clearance from the spokes to the caliper, but it was really close. I used a 3mm spacer for peace of mind, in the front. The rears were using the Focus SVT brackets and rotors. No spacers were needed in the rear.

I already have the rear setup going from the SVT* Just curious as to the Fronts...Hit me up with text when you get a chance!

Maybe not designed for the Fiesta ST, but they've certainly started marketing it for the Fiesta ST

and here's their official youtube channel documenting the install (they don't mention anything about needing spacers for clearance but based on pictures/what others have written it's REAL close)

appreciate the heads up. i just think a 6piston BBK is a bit unneccessary for my needs (just street driving and not even that spirited. damn you, Northeast!) and if their 4piston is actually smaller/lighter/narrower then I'd rather go that route if Wilwood can accomodate the fiesta rotor no problem.

 

[esp_martin]

I meant "fit the Fiesta" as in fit a 4x4.25 hat to the dynalite big brake kit. basically if they can take the hat from the 6 piston BBK and put it on their 4 piston dynalite BBK. they're designed for the same rotor thickness (0.81) but the "center registration" is a bit different (2.52 vs 2.50) if that even matters.

i just think the 4piston might be a better idea for street-use only Fiestas and if it's lighter then the 6piston then that's a big bonus. also wheel clearance is a huge issue for many Fiesta drivers so if this clears the factory wheels "with a minimum of 0.08" clearance" that's the big win.

GREAT IDEA! I'll be following in your footsteps.

obviously as its compatible for the front
try installing their rear kit on a ST

It works with OEM wheels without spacers, but barely. I ran it like this for about two months without issues until I swapped to Konig Hypergrams, which has plenty of clearance.

That's scary close! Hub centric 3mm spacer isn't gonna do any harm but a bad pothole just might

okay, there seems to be some confusion here so i'm going to be as clear as I can be so everyone's on the same page:

1) the whole point of this thread was me asking if someone could explain the wheel clearance diagrams. specifically the difference in caliper width between the Wilwood 140-11899 caliper and the 140-6163 caliper. *BOTH ARE FRONT DISC BIG BRAKE KITS FOR ABS SYSTEMS*

2) no one, not a single person, gave me an explanation of the wheel clearance diagrams (which is fine; still learned some stuff so thank you)

3) i *never* mentioned anything about a rear brake kit. Maybe someone else did in passing, but that's not the focus here.

4) i simply want to know if the posted wheel clearance diagrams definitively state that the 140-6163 caliper (the 4 piston) actually sticks out farther from the wheel mount surface than the 140-11899 caliper (the 6 piston)

Looking at the diagrams, the rotor width is equal but the .91 of the 6 pot vs the 1.11 for the 4 pot says to me that the caliper is a tad wider and would contact the wheel.

The height is .03 lower for the 4 pot but that only makes matters worse.

Nothing a 3mm spacer couldn't correct.

Checked Summit Racing for pricing on the 4 pot and according to them, it won't fit.

Might be the similar situation with base S550 Mustang GT front 4-pistion calipers vs. 6-pistion calipers that comes with the Performance Pack. Six smaller positions allowed for a slightly smaller caliper vs. one with four larger ones.

thanks for checking. wilwood customer service never got back to me. either way, if the caliper actually does stick out farther that negates the biggest reason i was thinking of trying this out. it's just interesting as the 4 pot is marketed to FWD mid90s cars with much tighter clearances (or so i thought)
