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

[gomer_110]

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.

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.

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.

Damn it dude. If I would have known you was at PittRace. I would have come to see you.

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?

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!

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

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

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

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.

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.
