Just placing some ballast weights equal to your weight in the drivers seat should get the job done if they won't let you sit in it.

Replaced the end links with some oe style ones with greasable joints. We'll see how long they last. Has anyone with a hotchkiss front bar found a quiet, reliable endlink solution?

edit:

Maybe I'll cop these lol

gomer_110 04-06-2017 10:40 PM

I have the SPL endlinks and haven't noticed them to make any noticeable noise.

How long have you had them and how often do you street drive your car?

gomer_110 04-07-2017 06:49 AM

I've had them on for about 3 years. During that time the car has seen maybe 30-40 hrs per year of street driving under varying conditions. That is also with 1100 lb/in springs up front so I probably have less movement than a stock car.

Hotrodz 04-07-2017 09:56 PM

Mine will squeak or make noise from time to time. It is a combination of the sway, solid bushing and spl upper A arm. I just give them a good shot of lithium grease and they quit right up.

PharmDZ 04-07-2017 10:14 PM

My SPL end links were starting to clunk - as per my shop they said there was some play but nothing serious. I had them rebuilt just to prevent failure and stop the damn clunking noise. Haha I've had them on for about 3 years now, and daily drive the car + 10-12 autocross events per year.

Has anyone figured a fix for overheating the clutch? I run two drivers in the south and after some consecutive runs the clutch gets hot and feels soft.
Also I recently replaced stock pads with hawk hps+ and have some ice mode/and lock up fairly easy from a higher stop, running square wheels does anyone think that's the issue? Has anyone had this problem and ran a slightly taller rear? Anyway to stop the computer from doing this without pulling any abs fuse?

Rusty 05-16-2017 10:30 AM

Bleed your clutch with a good brake fluid. Then wrap your clutch line with insulation. I used kaowool.

When you get ice mode. Is one of the rear tires starting to lock up first? If so, you might want to run a less aggressive pad on the rear. That's why alot of people run the 10/8 combo.

I hope you wrapped the kaowool with something on the outside of it. Otherwise I'd sure like to know how it hasn't:

1) fallen to pieces yet, and
2) become saturated with road grime and lost a lot of it's insulating properties

Personal experience is that the carbotech XP series pads are overly aggressive for autox. Used them for awhile (xp10/8 combo) but over all just way too grabby. I've since gone with Ferrodo DS2500 pads and been much happier.

I have no experience autox-ing but I have done my fair share of research on brake pads and gomer is spot on about using less aggressive pads than those used for the track. Some stick with oem and it depends on your own braking style or lack there of lol!

I used motul when the clutch was swapped, stainless lined, guess I can wrap it and see if that helps. It felt like the fronts where locking up more, I still have the stock pads, I may try that out next run. Thanks

Don't worry. I wrapped the kaowool with header wrap. :icon17:

About the brake pads. I don't autoX. Just going off of my experience at the track. :driving: I'm also probing for more info from him.

I've tried XP10/8 and the AX6 pads. Nothing is better than the stock Nissan pads FOR AUTOX in my opinion. The others put me in ice mode since they are too grabby and you're usually always trailbraking in autocross. That just freaks out the system in this particular car. PLUS the stock Nissan brakes are already great and the others just bleed off too much speed!

I recently had to bleed my clutch fluid after the Blytheville ProSolo. Got a little squishy. Motul fluid is great but it doesn't last as long as the low temp fluids...at least that's my understanding and experience with it. Lasted about a year.

zpower86 05-24-2017 10:08 PM

I posted on FB to bring up the "370Z should be in STU" discussion again. If there's nothing in the works I'm probably going to sell. :/

Feel free to chime in to help move the 370 to STU.

Not to be a d!ck, but this is a lost cause for the moment. The only way the 370Z gets moved to STU I see is when the boost buggies get faster with the allowance of tuning boost tables and leave the 350Z in the dust. At that point you could probably make a reasonable argument the 370Z wouldn't be an overdog for the class but instead have parity with the now slightly faster boost buggies. As the ST classes won't have open boost until next year the earliest you could make a data based argument for the move is mid to late 2018 meaning 2019 at the earliest before the 370Z gets moved.

Why not just go to ASP? I hear race tires are fun. :tup:

zpower86 05-25-2017 09:17 AM

The purpose of the post is to find out what's going on. I'd hate to sell the Z for it just to be moved to STU in a year or so.

I'll put my 2 cents in again, but I agree, I think it's hopeless. I really was hoping for that as well since my car is basically fully built for ST except for having to change my test pipes to high flow cats and pick up a set of 285 RE71R's

Looks like there will be an SCCA Town Hall webinar for STREET TOURING on June 6th. Register here to discuss the 370Z moving from STR to STU.

I was talking to a friend who owns an sti and he brought up the idea of giving the higher power coupes their own class. So essentially move the the z34, z33, corvette and maybe cayman to a supplement class of their own. I think that would be a good solution as well.

IMHO, supplemental classes are just stupid. Either make a "real" class or don't. The use of supplemental (and/or regional only) classes just makes it all that much harder to go from regional to national level competition.

The real answer to all this is the argument:

Currently in STU with no boost adjustment allowed,
350Z performance = STI and EVO performance

Starting next year in STU with open boost,
350Z performance < STI and EVO performance

and to return some parity to the class add the 370Z so that
370Z performance = STI and EVO performance

Anyone participate and bring up the classing for ST?

gomer_110 06-07-2017 09:48 PM

I sat through it. While the 370z classing wasn't a discussion point, classing was mentioned briefly. It was mostly to do with making ST more "all inclusive" so that it can act as a step between street and street prepared. The STAC and SEB members in attendance basically punted and said something to the effect of "if the membership wants this then we could look into it".

TLDR; sitting through it was a huge waste of time.

cjwsrt6 06-20-2017 10:44 PM

Has anyone else accidentally wandered onto the Z forum on Facebook and just sat there wondering if it's easier to sell or burn their car?

gomer_110 06-22-2017 11:47 AM

New fasttrack has come out,
(July Fasttrack) and moving the 370z from STR to STU has finally made it to the stage of going out for member input. Now is the time to flood the STAC with letters on why this is a good idea. Best bet is probably still to go with the argument that the boost buggies are getting faster with the open boost allowance and the 370z could be used to restore parity to the class.

Edit:

Here's the letter I wrote in support of the move. Feel free to steal any of it for your own letters.

Quote:

1) The 370z is in line with the overall philosophy of the class.

2) The reason 370z's are not currently showing up in the ST category is that the car is currently severely hobbled with the narrower than even stock wheel and tire restrictions. The car needs STU wheel and tire widths to be any fun.

3) Numerous 370z owners left when the car was moved from CS to BS in the street category. Many of these owners could be lured back if the 370z was moved to STU.

4) With the upcoming change to "open" ECU's it can be anticipated that the boost buggies will get faster and ruin the current parity in the class. By moving the 370z into STU this parity can be restored.

5) With regards to "screwing" those that have recently built an STU 350z, precedant has previously been set that adding a newer generation of a car model to the same class as its previous generation is ok. A recent example of this is placing the ND Miata in STR which immediately obsoleted the NC Miata.

6) As I've seen false information regarding the possible power the 370z makes with ST legal mods I would refer the STAC to the numerous data points that are available online showing that the whp with legal ST mods is approximately 330-335 whp.

7) and finally, Bryan Heitkotter doesn't see the 370z upsetting the competitive balance of the class and believes the 370z should be moved into STU.

Yep. Instead of forcing reruns for the car or two behind me I just opted to get out of the way quickly. If it had been at nationals I probably would have said screw them and slowly reversed through the chute, reruns be damned.
