Please avoid buying from CZP if at all possible. Some shady stuff they did in the Z32 community, so I suggest taking business elsewhere.

 

That sucks. I was going to order splash guards from them,2 ballasts in 2 months. Stupid winter.

My last set flew off at VIR

Subject: Re: Question: can Setrab Oil coolers be mounted in any orientation?



good info! the cooler you have...50-625-7612...is a bit larger than I would ordinarily suggest for the application you indicate. It'll be fine but note: our coolers are very non-restrictive by design...your gpm will be fairly low and mounting such a large cooler with ports down may mean that the oil can enter/exit the cooler before completely filling. Optimally, we'd put you in a 50-616-7612 or smaller...or a multi-pass cooler. We'd make such recommendation in order to ensure the oil's exposure to the entire internal surface area of the oil cooler. In this instance, since you already have the -25 row unit, I'd recommend either placing the ports at the top of the installed cooler or if the ports are on the side, enter the bottom/exit the top.



Go well,

OK, guys so I'm plalnning on making my first HPDE experience at Road Atlanta in June and since my plans are to turn into SpecZ, I'm going to keep the brakes to specs. Since I'm not running slicks, I'm thinking of doing like Hawk HPS+ or Carbotech XP8. Since the rules are to use blanks, I was looking at Centric and EBC rotors. Do you guys know the differences between the two? I'm going to be keeping them aside as my track sets and would like a set that will last a good bit with a good heat dispersion.

 

Use centric blanks and XP10.

 

Would it be good to go XP10 Front/XP8 Rear for brake bias since I'm running with no ABS?

 

I'd just do XP10 F/R but that's me. Personally I had XP10/8 and did not like them. I switched to ST45.

 

Agreed, the difference between the XP8 and XP10 doesn't seem to be as great as XP10 and XP12. If you are going to get track pads go ahead and get the XP10 all around. The HPS+ pads will be gone in one, maybe 2 sessions.

 

Thank you very much for the information. I'll then consider the XP10's all the way around.

 

Awesome! Thanks for all the info!

BTW: my mounting position appears to work fine...
Note: My fan is a "sucker"...I use becuse that is what I had in the shop already. Either a sucker/blower type should work fine

 

What tires are you running? (Treadwear rating)

 

These are what I'm using at the moment:

Fronts - Achilles ATR Sport 225/45-18, UTQG 400AA
Rears - Capitol Sport UHP 245/45-18, UTQG 360AA

 

You can run any brake pad with those tires for your first event. A) You won't be driving hard and b) those tires are no bueno.

Please take any further track talk to another thread, instead of the SpecZ-specific thread.

 

I'm grabbing some parts from a wrecked Nismo (body panels) for my 2004 spec Z. The owner is also offering up the body dampers as well but I'm not sure they would benefit a car with a cage. Has anyone added them or have an opinion on whether they might be worth the extra $ and hassle to install?

This is the description from Nismo... Even if the car body is reinforced and made more rigid, road surface input through the tires and load shifts during cornering make the entire body act like a spring, causing the occurrence of micro vibrations. The performance damper acts to control the transmission of micro vibrations to the body. During circuit driving, micro vibrations from the car body are transmitted through the steering system to the driver, resulting too often in unnecessary steering corrections. With the performance damper installed, however these micro vibrations are eliminated and excessive steering wheel handling is no longer needed, resulting in more stable handling.

 

Based on discussions with Nissan through SpecZ's Jeremy Croiset, it's not worth it. The added body rigidity and damping goodies are supposedly more Nissan marketing than anything of major value. Here is more info for us to consider ourselves though: http://www.xenonz33.com/Files/Nismo2007.pdf

 

Ran my first race with the car this past weekend with NASANE at NJMP Lightning.
Did the test n tune Friday which helped get the car sorted a bit more. Since LRP we added a brake bias controller. We choose the lever controller from Tilton and have it set up so we can adjust each rear wheel individually. The levers are mounted where the master cylinder is located.
Practice session #3 saw me run wide out of T1. I came in to have the car looked at. The brass T-fitting for the oil pressure sender unit broke. A quick trip to the parts store and 30min later she was back up and running.
Saturday, race day, I'm the only Spec Z there. Based on my times I'm moved to thunder. During qualifying I go off in T7. I come in and the grid marshal looks over the car and says I'm good. I go back out and again go off in T7. I had what felt like no front brakes, but my pedal was fine. Go back in and the same oil fitting broke. We remove the oil pressure sender unit and just run the temp sensor. Bad thing is was 5 sec slower than practice and qualified 39th out of 45 cars.
We get the car fixed and I'm able to start the race. Got some great video that I need to edit and upload, but I was able to finish 23rd.
Sunday I request to be moved to Lightning since that's where Spec Z runs. I make a brake bias adjustment and qualify 4th matching Fridays Practice times. During the race the car feels good, the tires got greasy but I was able to improve .2 seconds.
The added weight from last year makes tire management a must. We had the car scaled and with me in it, its at 3505lb. I know I can lose 100lbs. But the last thing I want is to accidentally come in under weight.
The car ran well. I wish it was lighter as that would help tire wear.
There's more changes to be made and improved upon.
All in all it was a good weekend. I just wish I had spec z-s to run against

 

That's how I feel! What brake pads were you running? PM coming for a separate discussion. . .

 

xp12 front
xp10 rear
Tilton brake bias controller

 

Slightly off topic but how long are the XP12s lasting you guys who run them? I ran a set on my 370Z and absolutely loved them but they barely lasted 4 cold track days (2 road atlanta 2.5 mid-ohio). My in progress SpecZ car has XP10/XP8s on it now and those seem to last forever (and keeps costs down as a result) but it feels like a big step down in braking compared to XP12s.
