These people, formerly known as Winning Power in their early years have been a supplier for O.E. & Formula One brake applications for many years. They are a proven brand, with a proven track record, and I've seen that many G35 & 350Z owners are pushing these brake systems with lots of satisfaction. So I called them up and have been asking tons of questions over the last year, and they do offer front & rear brake systems for 4th Generation Maximas. Has anyone on the forum tried out their kits over the years? I'm tempted to be the first one, to do a 6-piston front (L6) & 6-piston rear (S6) set-up. I just want feedback from those who have used WP Pro Brakes in the past, if anyone!

Here is their website: http://wpprobrakes.com/

 

hmm sounds interesting. i wonder if its a direct bolt on for front and rear or it need brackets made up after paying that 2000$ price tag.

 

They told me everything is direct bolt on & everything is included as a complete kit & designed to work seamlessly with our master cylinders.... it does sound interesting; especially since our options are limited to the Wilwood Fastbrakes, the now nearly impossible to find discontinued Brembo Gran Turismo's, The AP Racing Big Brake Kit, The Stillen Kit, and the other kits made by our talented forum members (none which offered a matching rear kit). It's kinda cool to know there are other options out there, especially for a complete rear set-up & not just a pad and rotor upgrade.

 

Forum people, I just got this message from WP Pro in my e-mail yesterday, and I thought I would share. If we can do a group deal for a rear Big Brake Kit (with at least 8 committed orders for a 4th Generation rear BBK), we can have a reliable rear set-up in production. They have a 4-piston setup to match a possible front 6 or 4 piston set-up for those who already have a BBK already. I will try to post this in the group deal section as well.

Hi Alex, thank you for your help on the forum, I've talked to the machinist and the engineer about your concerns, the old brackets style require some modifications on the cable lines, and we simply havn't stocked any of them in the last few years, to make it a complete bolt on affair is not an issue, but it will require a complete redesign of the bracket, and unless there are at least 8 committed orders, we won't be able to put it in production, as the set up time would make a single kit cost 6x of what I quoted you previously.

Also, we've updated the rear set up with new caliper design, they use the same pads, the biggest differences are the amount of pistons and dust boots, the S6 remains a 6 pistons that doesn't use dust boots, this is generally ideal for racing as it has built in heat shields but do require periodic maintenance such as cleaning of the pistons, the R4 is 4 pistons that uses dust boots, it is a maintenance free caliper as we call it, can be used all year around without much cleaning.

If you can set up a group buy on the forums, then we can put it in production and offer quite bit of discount for all kits, for the rear, you must have 8 kits, the front has no minimum, but the price break down would be as follow, all prices include shipping directly from factory and include extra set of pads.

Rear:
336 x 30mm rotors with S6 or R4: $1800, (a kit like this is usually $2300, the previous version is only $1945 due to fabrication involved when installing).

Front:
336 x 30mm rotors with L6: $1745
360 x 30mm rotors with EX6: $1845

the prices of the rear are only applicable if there are minimum of 8 orders, in case that it doesn't, the front prices are applicable if there are minimum of 6 orders for the front.

Sincerely
WP Pro North America

Let me know if there is interest to start a group buy for an R4 set-up since it seems like the more practical set-up for our braking needs.

 

Is anyone interested in a group buy for a front or rear BBK??

 

..... driving that many pistons even using the smallest avail piston sizes for those series calipers will most likely yield terrible pedal feel, if not bottoming out the MC/Booster unless you upgrade them as well.. Unless that company is using caliper with smaller than usual pistons etc.

Get in touch with Matt93se he has done several brak kits and knows the math behind it.

I'm all for BIG brakes but i think function over form is something to keep in mind when it comes to brakes. Not just how to fill in dead space behind 18" wheels. Most real performance/track guys dont even run 18" wheels cause of sheer weight. lol

I run Dynalites in the front with a 11.~ inch diameter / 28mm thick rotors from the 300zx/ 2001 q45/ 2008 nissan quest etc. Also the price savings of getting generic rotors from local parts store helps to reduce the overhead of havign better brakes.

The 4thgen being a lighter car, it can def. utilize the dynalite. There is a HUGE assortment of pads from SUPER HEAAVY DUTY to streetable pads @ about 40$ a set . No queeking etc. for DDing.

I think its like $30-40 for above mentioned rotor at parts store. I usually end up changing pads and rotors together cause its like $8~.00 for set of pads and rotors. Maybe will go with brembo or something when it gets to tracking/abuse situations but for DDing, not necessary and where would you source the custom rotors etc. and at what cost?

Keeps my stock 15" BBS happy in winter, my 16" BBS happy in the summer. keeps my spare donut happy year round. The pedal feel is AMAZING; No sponge.



for the rear all that needs to be done is increase the rotor diameter accordingly to the front if anything. That will give that TQ/ +surface area advantage.

For the rear the design/ quality of our caliper is terrible. They are prone to lockup etc. IF you wanna get crazy, then adapt a braket to accomidate the below caliper with OEM diameter comprable rotor or like 12" if your going 13" upfront.

it is single piston, has mechanical park brake option, and since its a better caliper in terms of design and quality it wont crap out like the OEM ones do especially in snowy areas.



I think even Matt switched from the 300zx to dynalites on his 3rd gen. Yes matt, I secretly am stalking you.....

My post isn't to discourage you, but to shine a light of logic. Utilizing system with OEM rotors or hardware makes the maintianance of the system easier on you/mechanic/wallet. The cost of two piece rotors etc drive up $$. I've seen serveral people with custom kits using two piece rotors driving around with warpped rotors cause they dont know where to get the custom rotor or cant change it cause its too expensive.

I'm all for one-off stuff, but sometimes you gotta look at it from multiple angles. Have you thought about the q45 upgrade? I know its not 4 piston, but you would be suprised at the brake improvement on a 13" rotor with two pistons, over the stock. OR hell, change to the 300zx up front with the 300zx master cylinder OR get a brake booster from like a q45 or something bigger. That way it will improve your pedal feel + more pad options + coupled with a larger diameter rear rotor will give some serious stopping power + easier on your wallet.

lol, I just noticed your in NYC. you can see my brakes up close if you want an idea of what your options are or discuss this further.

 

did I hear my name?

Actually I've had a multitude of brake kits on my car...
stock
Dynalites +skyline rotors
dynalites + 13" custom 2-pc rotors
my 300ZX + '04 Maxima rotor kit
my brackets w/ Z32 calipers and 12.6" 2-pc rotors
wilwood Superlites + 13" 2-pc rotors

All of them performed well enough on the street. All of them saw track use too. All of them held up fine on the track but the stock calipers, given the proper pad compound. even the stock calipers would have been okay if I'd used some $$$$$ race compounds, but I'm not paying $300 a set of brake pads. That's why I went to Wilwoods. $60 a set for dynalite pads and $100 a set for Superlites (and they last 3x as long.)

as for piston sizing- yer on yer own. too much math for me to simply do for someone. the equations are listed on StopTech's website in their white papers. grab a calculator and do the math. it's just some mild algebra.

 

... the superlites and dynalites have the same mounting locations correct?.... or let me rephrase that, it has the same distance between the mounting bolt holes? You know what I mean, making them interchangeable long as you have the correct thickness rotor right?

 

nope. look at the drawings on their webpage. http://www.wilwood.com/Calipers/CaliperListLanding.aspx

dynalite is 5.25" spacing and superlite is 3.5" spacing.

 

omg.,... YOUR right.. I was reffering to the same thing, but looked at the "narrow" dynalite.... dammit.. the bracket I have is for the 5.25" mountable dynalite. I think I'm gonna switch to the dynapro with dust boot for the pistons. Its been about 4 years on my dynalites w/o a rebuild etc. I wonder if wilwood would give credit or something towards the dynapro..

 

uhhh no.. they sell enough of those things and they're cheap enough, they won't bother with trade-ins or anything. not to mention you don't buy from them directly- you buy from a retailer.

why not just rebuild the dynalites you have? A seal kit is like $15.

what size are the pistons? I might consider buying them off you for the rear of my 240...

 

I figured they wouldnt give credit or anything. I think it is the 3" piston suface. I will check and let you know. I might take you up on the offer because I have been EYE SEX-ING these below...

with the 16's BBS mesh I just picked up as opposed to the stock 15" I might be able to clear the 6piston while using the same 11.~" rotors. I can really appreciate the larger surface area pad they offer for the dynapro6. All with maybe a Brakebooster upgrade.

When snow melts, Im gonna try the wheels on and take some measurments.

 

guys awesome information! Thank you! HomarMAC, i think i might take you up on that offer to check out your set-up. I've personally locked up two set's of OEM rear calipers living in NYC, so I completely relate to this situation! thanks for the info.

 

6 pistons ? isnt that a bit overkill ?


IMO nothing beats a very good set of Brakeman Cermanic Pads w/z32 Calipers setup with either a 12.6 OEM rotors or 13 inch cobra rotors.

the rear 6 piston is overkill since most of your stopping power is in the front.

but I guess to each and their own , if you have money to spend on something like that. I hope your making enough power to use the brakes to full potential.

 

Then you have a LOT to learn, young grasshoppah.
those are fine for "playing around", but if you really want to get serious, the Z calipers become a major weak link and a cost factor..
Race compound pads for a Z32 caliper are 2-3x the price of the same pad for a wilwood caliper, and don't last as long. the rotors are also heaaaavy. the 2-pc rotors on my car are the same size and are 6lb per rotor less. ones designed without safety overkill in mind are 1/2 the weight and can provide a noticeable performance advantage over OEM style stuff.

 

z32 TT guys have been running the stock caliper , 13 cobra rotors and brake man pads for years , these guys including the one I have are making well over 800whp and stopping isnt a issues.

we are talking about street cars , not road or drag cars, if we were going to talk about drag cars then I would say yes a lighter caliper and 2 pc wheels.

since most maximas probally wont see over 600-700 hp , the z32 calipers and a good set of pads will do enough stopping power.

remember this is a Maxima site, and not everyone has the money for big setups.

its why I ditch this setup that I offer 6 months ago for the A34 owners






US Brakes light weight calipers 4 piston setup with 14 inch 370 rotors.

since there wasnt much of a Interest I decide to stay with my current 13' and z32

in the end how many maxima owners acutally road race ? besides you Jeff..
maybe a handful that you could count on your fingers, I dont really considering short attention span racing.
