How did Mueller do the 6 piston kit with the 14.125" rotors

 

Whoever answered that email was an inept douche bag because i sent him 3 more emails with examples and they didn't answer.
Probally had to peice together custom peices which means theres no gaurantee on bias. Therefore no off the shelf kit part #

 

Vivid racing has the 6 piston trophy kit listed on there website, but nothing for the 4 piston front or the 2 piston rear kits. Might try e-mailing vivid and see what they say. Maybe a year ago they sold the 6 piston kits but no longer make them? Seems weird to me.

Call Zeckhausen Racing. They are the US importer and are very knowledgeable. If it has been done they will know about and what was used.

It is just a different caliper mounting bracket.

 

Spoke with Stoptech about this, as i ordered the Trophy 6-piston fronts for my Evo 8 a while ago. Will be getting the Rears soon.


I can tell you they are still available. Part # for the Trophy 6-pistons fronts are 83.622.6700.R1 which i have in my possession now

Lead time is about 2 weeks to get. They also have the none trophy 6-pistons in various colors (Yellow, Red, Black, Blue and Silver) with a lead time of 2-3 weeks.

 

Which rear part # are u getting to balance this?
What I dont understand is how they can have one 6 piston trophy for the front when they dont know whether or not your upgrading the rear.
This does not seem to be the case as they usually offer a full f/r kit to make sure the balance is right.

 

It looks like Stoptech does offer a 2 piston rear upgrade for their Trophy kit and their Street kit, or whatever they call the non trophy kit.

From my experience on stock brakes and track pads, the rear brakes dont seem to get nowhere near the abuse the fronts seem to do. Thats why you can get away with front track only pads and street compounds in the rears. I can see the argument for the aftermarket big brake kits, like AP Racing, who only offer a front big brake kit.

I think the 4 piston front Trophy kit is all you would need. The 6 piston caliper looks much cooler tucked behind the wheel, but for most folks is just gonna be added weight. Using their 4 piston fronts you may not even need to worry about getting their rear brake kit, unless your concerned about the aesthetics of a nice freshly anodized front stoptech caliper, and a faded red brembo rear caliper.. ymmv.

 

Problem is that there is no difference between a six piston front rear brake and a four piston front rear brake. I already know from a similar setup car at my local track that the 4 is not going to cut it so may as well do it right the first time.

 

Brembo and Alcon offer 6 piston fronts and 4 piston rear calipers then.

 

Show me the link to the complete kit with proper bias designed for the evo cta9 and balance for 14 inch in the front min. six piston front with matching rear caliper setup.

 

The Rear Trophy 4-piston BBK kit is 83.622.0043.R1

 

That number doesn't come up on the stoptech website. Where did you get this number from? Stoptech has been on this new website for the last year I think.

 

Well, If I'm understaning it correctly, your saying that a 4 piston front caliper isnt going to cut it for you, so you need a 6 piston front? Ok, well Stoptech makes a 6 piston front kit. If you also think that the rear 2 piston setup is not gonna be enough, then they also offer a 4 piston rear caliper setup.

I think that when they are talking about their balanced setup they are just referring to keeping the 2 piston rear caliper setup, where alot of other companies use a 4 piston rear.

I have upgraded big brake kits where I replaced 2 piston rear setups with 4 piston rears with larger rotors. Thats where you throw the bias off. Without some manual bias adjuster I was locking the rear wheels much eariler than the fronts. I beleive that is why most big brake kit companies only offer front kits--Like AP for example.

Even if you decide to get a 6 piston front kit, I dont think you will throw the bias off on an evo. Lots of oem examples where the base model has regular 2 piston brakes, and the loaded example will have an upgraded brembo front 4 piston and usually the same rear 2 piston as the base version. A few examples off the top of my head is the 2010ish mustang with the brembo brake package vs. base, the cla45 amg vs cla 250. So for oem applications Im sure if the bias would have been off they would not produce them like this if saftey would be an issue.

I may be wrong, but all Im saying is that maybe you are over thinking this a bit about the bias. I know the argument about Stoptech claiming they are the only ones addressing that issue-- but you cant beleive everything you read. Just sayin.

 

Unlike some name brand humpers i'd rather buy based on claimed fact from a company than "assume" it.

 

One thing that came to mind was that if you're upgrading to this kind of stopping power balance has more to do with your cars weight and spring rate than having matched calipers f/r. To properly use a bbk on both ends you would need some certainty about spring and weight transfer. Ergo the numerous combinations to achieve the same braking result .. pedal to piston and all the brake pads in between multiple bias adjustment. Something a twin mc top mount pedal box would be efficient at adjusting. First measure braking temps and decide if the rear is even needed. I'd love to have a huge braking kit all around but if cost vs benefit dictates the front only then that's what I'd do
