why does no one talk about upgrading the rear brakes when going to a bbk?
you gotta keep the bias the same or the car wont feel rite, rite?

if you increase the front brake size by 20%, you should increase the rear by 20% also, rite?

 

Most of the braking is done with the front brakes anyways.

I wouldn't bother since Irish44j didn't upgrade his rears

 

Well there is a little more to it than that, but I think it would be easier just to get a bias adjuster. If you try to go the OEM route for rear brake upgrades you'll probably have to convert to a drum ebrake which means lots of $$ yourself or Matt's ~$1k rear Z32 setup, which I'm uncertain if he's still selling.

 

 

in theory, yes.

in practice....eh, not really. You can also mis-match pad materials to influence bias, or get a bias controller.

I personally have had no bias issues with upgraded fronts and stock (+ss lines and HPS pads) in the rear...

 

Two PM's over the last year and no response from Matt, I guess it's safe to assume the rear Z32 setup is no longer available. I guess "cash in hand" wasn't enough to warrant a response.

Don't sell your business and bring it back Matt!!

 

Actually, I'm going to make your day...

1. I have 3-4 of the rear brake setups left. I've got paid orders for 2 of them, but I haven't had time to make them. (one guy's been waiting VERY patiently for over a year for it. talk about an understanding guy!!)... I had another 65+ hour week this week and have two local customers coming by for work on their cars this weekend. it never stops!

2. After some talks with my family, my parents will be taking over the parts of the business that they can do. I won't go into personal details on the situation, but most of the parts will be available again soon.
They'll be taking it over when I go up for Christmas, so expect to see product ready to ship around February.

 

Now this is good news..

 

Please count me in for a rear Z32 setup Matt, as I've been wanting a kit for a while as well (as you know).

 

So, now that Matt has stopped making more rear BBK kits, what are our options?

I'm assuming that the rears are more complicated than the fronts because of the e-brake compatibility, correct? What all is required aside from the rotor and caliper? I would like to do a z32/cobra setup on the front, but not if it throws the bias off. (not to mention it would probably look a little odd with a 13" rotor up front and the tiny stock 5th gen in the back)

 

Bias adjuster. The only way to restore the oem bias using an adjuster is to restrict the front brake force. Which would negate the front bbk install. Remember you can only restrict flow.

 

I'll only build another batch of rear BBKs if I have 10 sets paid for up front. It's taken me 3 years to sell the first 10 I made. not enough ROI for that kind of initial investment from me.

 

What about what you said here (below).....??? Do you have 1 or 2 sets left? Is the profit margin really that small that you can't build a kit as you get paid in full for a kit? If you don't mind me asking....why don't you push your rear kit more? Start a group deal? Generate the interest...you know. I bet a lot of people don't even know your kit exists...

Stating that you'll only make them again if you get 10 orders=extinction of your rear BBK...because that will probably never happen IMO. I hope I'm wrong though.

 

there are some threads already about this with simple mathmatical calculations to show you relative bias changes with some of the respective brake kits available to our cars...

http://forums.maxima.org/showthread.php?t=358983
in that above thread, try to steer clear of the setups that add significant front bias though...as our cars only have minimal front traction as it diving into an apex trail braking without asking it to do yet even more braking...

it's all neglible mind you, but if you absolutely want the most balanced braking bias and overall balanced car you are often forced to choose between gaining some front bias to reap rewards of less fade which is a serious hurdle for our cars if taken to tracks and some canyons hence the extra front bias is worth it within reason of course...autocross on the other hand, upgraded stock brakes are usually more than adequate...

 

I counted wrong. I only had 1 set left which is already spoken for, so I'm sold out.
the profit margin is very low on these parts actually. there are several custom CNC milled parts in it, some of which cost over $100 each even when I buy in large quantity.
Last batch I made, I forked out $4000 up front for just the machined parts and still had to pick up the drum brake parts individually to finish off each kit.

If I charged anything for my time to develop and produce those parts, I'd be selling them at a loss.

So frankly, I'd rather spend the $5000 on a roll cage for my race car than to buy a bunch of parts that are going to sit on the shelf for the next 3 years. I enjoy helping out the Maxima community, but it's just not smart business.

 

Bummer. Thanks for following up and letting us know though. I guess I'll just keep my eyes peeled for a used kit in the for sale section.

As for everything else you said, that's totally understandable. Thanks for sharing.
