Here is the latest installment of Forza forums Heavy Metal Affliction which this month features the Doran Racing Nismo 370Z RC.

Great stuff!

Not really related but ended up watching some of the video included in that link.

This must be a crappy feeling when you go to slam the brakes and nothing happens.

Awesome man. Good luck this weekend, I really wanted to make it this year but have been working out of town this week as scheduling would have it. Need a Nissan on top!

Good luck guys hope you get 1st place this time. Noticed in a pic that you guys have brembo brakes and not the Akebono brakes. Any reason why? http://compass.xboxlive.com/assets/4...HMA_5_1_13.jpg

'weight' is the first thing that comes to mind

Akrbonos are not a racing brakes. They're just a big brake. The materials used is night and day over a real caliper. The rubber seals even melt and I bet beyond a 20min track session they'd completely fail. This goes for the STI, Cherokee SRT, Regal GS etc that all have Brembos. Check out a real BBK parts list to see what I mean.

Factory stuff is always kinda junky. You'll never get the best of the best unless you buy an Aventador with carbon brakes. Like an Audi with a Bose system. That's no where near a real Bose system!

Depends. Some guys race so much they find a blank rotor that works because replacing two piece cost so much. The caliper weight is marginal unless you go with Stillen's new kit made by AP racing, that cuts the caliper all up so there's like no material left.

What would you recommend as an upgrade that is cost friendly, let's say less than 2k?

I think anyone aftermarket has done their fair share of R&D and would be an upgrade in materials. Under 2k I don't think is going to happen. I'd look to see costs on Brembo, stop tech, wilwood, and AP if it was me. But even with those they are going to have cheap to expensive trim levels of each. I also don't think you need to upgrade unless you're Doran doing 45-1hr races. Pads and cooling ducts might be all you need for track days.

On a side note you could be under 2k if you sell your OEM stuff!

interesting intake system...wonder where the MAF's are?

Yikes

;)

Wait that's a DS car?! If there's no MAF then they figured out speed density tuning on the 370z.

We don't run MAF. Bosch Motorsport ECU

Or that haha

Does that say Front Wheel Drive?

Typo

I didn't know that but now I do, thanks. Sucks that the ST class has to run stock brakes, good thing GS dosent.

for autox? im sure stock brakes are more than ok for X! but tracks were you are reaching 150mph and having to stomp on them over and over is another thing.

I meant ST as in the racing class in the CSC series. The ST guys have to run stock brakes and stock pads. I was watching the race and they were talking about how have to be really light on brakes because by the end of the race they are down to the backing plates.

Wow that's scary! OEM pads?! They want someone to die?

That can't be true..

Edu-bacate me. Why would a post market ECU not need a MAF? I thought part of the point of having an ECU was MAF data? Is it something specific with that ECU or your intake?

I would say the car is speed density tuned instead using the map sensor. This is just a guess however.

ST class cars have to ur the OEM calipers for their car. Pads are open as log as they fit the oem caliper and approved rotor.
In GS we are allowed a slight front rotor diameter increase over stock rotors.
We are also allowed a 4 piston 2 piece caliper on te front and need to run a factory or approved rear caliper and brake pads are open. GS class cars are also allowed an approved racing ABS system.
Part of the uproar in GS this year is the addition. Of the Z28. It is not really suppose to be in GS as its way too much car for the class...hence the magazines compare it to the GTR and Porsche GT3.
We are not a GTR :(
The Z28 showed up at Daytona with 6 pistonAP racing front calipers and 4 piston AP racing rears... 6 piston calipers are not legal for GS... But somehow they got approved on a car that has a 7 ltr v8 also.
Rule # of racing... Politics

Look up what I said about speed density. Lots of subis run it. You'll have reading material for hours. But I believe its a MAP thing that works great but you need to retune if you drive out of state as different evaluations and stuff need tuned for right then and there since it can't change on the fly like MAF can.

This isn't true. While they certainly are not on par with true racing BBK setups, I can attest that they do not melt and/or fail after one 20 minute track session. In fact, I know a couple guys that have hundreds, as in hundreds, of track hours on the stock Akebono's.

Whats this guy saying then?

I never said after 1 session they melt! I said the rubber seals melt, period. Then the sentence continued on saying I BET after a 20 min session they'd fail. Maybe its 20, maybe its 30. I wouldn't take the bet for a longer time.

Sure you can get tons and tons of use, but not all at once, you have cool down periods. I wouldn't race on these. These are track day small session brakes and as seen below, play at your own risk. I'm sure the guys you know kept it to 20 maybe 30 min sessions and not 1-2hrs like downshift. That's all I'm saying.

Cool had not heard of that before.

And in regards to brakes, yes there is just as big of variance in brake pads, rotors, calipers in any setup for different types of races.

To over exemplify, the best brakes for a 24 hour endure race are not the same "best" brakes you would use for a 20 lap race or 15 minute time attack or auto X session. Different things are good at different things essentially.

With that in mind, the Akebono sport brakes are really a pretty decent setup from my experience, comments, and feedback from others. Did a road trip a month or two ago with an engineer from Brembo and picked his brain. He knew more about brakes than any human I have ever met. His description of our brakes was "Not bad". This was after he threw a lot of other brakes under the bus, so I took it as a compliment.
