I'm looking to get a set of FRONT BBKs... Wilwood looks to be one of the more AFFORDABLE brands out there! I am curious tho why the 6 piston WILWOODS at this website :

http://www.arizonazcar.com/350zbrakes.html

are NOTICIBLY cheaper than this website's:

http://www.350zbrakes.com/

 

idk anything..........but there so sick

 

Great question, are they exactly the same kit?

 

The ones on the second site use a better caliper for the rear and have better machined hats for the rotors and keeps the factory parking brake. The ones from arizona z car are just made cheap.

 

They are 13" and 13.6".

 

What do you mean by saying they are made cheap? Aren't wilwoods wilwoods, regardless of who sells them? Or are you saying the rotors ane cheap? The price Arizona Z Cars is selling for is incredible.

 

The 13" rotors are also thicker and directionally vaned. Something doesn't look right with the hats that they're using on them though. The design looks improvised.

 

I don't think these are Wilwood "BBKs." I checked Wilwoods current catalog and they don't sell a Z/G BBK. I think these guys are taking Wilwood calipers and piecing a kit together, so the pieces differ a bit. The AZ price sure is great though - may be a case of you get what you pay for. It'd be nice to get a track test on the AZ kit.

 

Who makes the rotors in the Wilwood BBK? Thanks.

 

Wilwood does now have an official Z/G BBK in their catalog.

K I T COMPONENTS

BILLET SUPERLITE 6 PISTON SL6 CALIPERS

SL6 calipers are pure performance featuring a fully CNC machined billet body with
closed end bridges and a reinforced bridge to body transition. Center bridge body
bolts provide additional strength and positive retention of the pads. These elements
combine to make an ultra-rigid body that resists separation and deflection under
high load. Driver comfort and confidence soar with immediate response from a very
firm pedal. The SL6 generates high clamping force and balanced pad loading from
a race-proven differential bore six-piston configuration. Staggered piston sizes
distribute pressure to compensate for the natural variances in temperature, load,
and wear rate that occur over the length of the pad. Pad life is extended and
performance is measurably improved. Stainless steel pistons are used in all custom
show and sport performance applications for their low heat transfer properties and
high resistance to corrosion. Road race kits feature SL6/ST calipers with
Thermlock® pistons for maximum heat protection in extreme heat environments.
High temperature, square faced piston seals provide long service life in extreme
environments with positive piston retraction on release. Stainless steel SRS bridge
wear plates eliminate pad gouging and extend the service life of the caliper. The
spring-loaded action of the SRS plates also eliminates pad rattle and dampens the
vibration harmonics that contribute to pad squeal. Fluid tubes are dampened to
eliminate vibration stress and recess mounted for protection from track debris. SL6
calipers now come in red, or a high luster black anodized finish with style that will
catch the eye of the most discriminating enthusiast.


GT SERIES ROTOR HATS

GT aluminum hats are lightweight and strong to handle the exceptional brake torque
generated by the SL6 Big Brake system. The hats are specially designed for use on
the OE hubs without modifications or interference to the suspension or ABS
components. The hats carry Wilwood's signature and a black anodized finish that
prevents corrosion and enhances the overall appearance of the complete package
inside the wheel.


13” AND 14” ROTORS

Large diameter vented iron rotors provide substantial increases in cooling and
stopping power over small diameter OE rotors. All Wilwood rotors are manufactured
from premium grade, long grain carbon iron to provide long wear with high thermal
stability and resistance to distortion. The superior heat absorption and dissipation
qualities of a vented iron rotor are essential to preventing heat fade and realizing the
longest service life from the pads and rotors.


SRP ROTORS

For custom, show, and high performance sport driving, SRP rotor kits offer the
high-tech look and improved performance of a directional cross-drill and face slot
pattern. In addition to their aesthetic appeal, the venting and cleaning action of the
holes and slots will reduce pad glaze, dissipate surface heat, and minimize irregular
pad build-up on the rotor faces. The results are smoother engagement with
improved consistency and response at the pedal. Every SRP rotor is treated with a
silver zinc wash to reduce corrosion on the areas of the rotor not kept clean by pad
contact. SRP rotors come in 13” and 14” diameters.


GT ROTORS

GT rotor kits feature Wilwood's ultimate competition rotor with full detail machining,
asymmetrical face slotting and individual dynamic balancing. GT rotors run true and
smooth with extended rotor life and pad wear on applications subject to higher
sustained operating temperatures. GT rotors come in 13” and 14” diameters.


WILWOOD BRAKE PADS

Wilwood brake pads get fast response with high resistance to fade, long wear, and
the low rotor abrasion that Wilwood is so well known for. Specific pad types and
compounds have been selected for each application and are listed in the service
parts guide for each kit. Optional compounds for each pad type can be found on
pages 54-56.


CALIPER BRACKETS AND HARDWARE

Aluminum mount brackets are lightweight and strong. Each bracket is CNC
machined for precise fit on each specific spindle. Grade 8 or higher and AN style
nuts, bolts, washers and alignment shims are included in all applicable kits.


PLUMBING

Fittings and hoses for most kits must be ordered separately. A few noted kits do include
stainless steel flexlines. Otherwise, hose kit part numbers can be found next to each kit
in the ordering information, or with the plumbing information on pages 51-53.
NOTE Installation of Wilwood Disc Brake Kits may affect the wheel offset.
Reference Wilwood wheel clearance diagrams available on our web site.

 

Yes, I would like clarification on this as well. Isn't a Wilwood BBK a Wilwood BBK? Does Wilwood offer different grade / quality kits? Thanks.

I have my choices narrowed down to Wilwood, Rotora, and Stoptech.

 

I thought the same thing. "All the kits come with the same relative parts, don't they?" From conversations with a friend who owned a performance brake shop though, this is apparently not the case. Different places offer kits with variances (rotor diameter, rotor widths, hats, etc.). He never really elaborated enough for me to fully understand it though. If Wilwood has a 13" kit and a 14" kit, I'd think they'd all be the same regardless of vendor. That doesn't seem to be the case though.

 

I have been investigating the Wilwood brakes and talking with serveral vendors, including Arizona Z Car. Here is an email from Dave at ArizonaZCar:



My brake kit IS full race quality!
Have sold over 2500 brake kits in 24 countries, Hi volume + low overhead= better price.

Dave,



For the same price? I’m waiting of the settlement check. When it arrives, I will decide who to purchase from.

I am also looking at RMS HorsePower’s Wilwood BBK. Theirs have 13.6” X 1.25 rotors, but cost significantly more.

$1850 for fronts and for rears also. Since I don’t plan on taking my G35 to the track, I don’t need racing quality brakes.

Can you explain why your prices so much lower than the others I have seen?

Not the stock mechanical one, I have hydraulic line locks to serve the parking brake function.

Dave,

One more question. Do the Willwood rear BBK allow for use of the parking brake?

Regards,

David Berry

 

Got mine from www.fastbrakes.com

It's 13.6" & cheaper than Arizona brakes

 

I'm confused! Those prices don't look cheaper than Arizon Z Car's prices!

$1395 for the front set and $795 for the rears.

In stock.

Dave

Edit: OH, I see it now. $1350 for the front kit. How much did you pay for the rear kit? Or didn't you get the rear BBK?
