What are your allignment specs, and tires I am on 265/35/18 285/30/18 bridgestone pole positions

 

my alignment specs have nothing to do with your alignment specs

but try not to have too much rear camber (like 3 degrees) and toe should be close to zero as possible.

 

camber:
FR -2.0, FL -2.1
RR -1.8, RL -1.9

toe:
FR 0.02, FL 0.02
RR 0.10, RL 0.18

caster: FR 8.3, FL 8.5

corner balance:
FR 965, FL 1005
RR 805, RL 848
cross = 50%

tires: kumho ecsta mx's, 275/40/17 all around. i think the pole positions tend to get greasy fairly quickly, but they do have a very stiff sidewall.

 

thats true, becouse rear toe on my car helps me a bit... Less camber in the rear than the front

 

I corner ballenced myself, I think i got to 49.5 and gave up on the cross weights

 

once question about tire warmth, Pocono has a long slightly banked straight, where you get up to about 140, Is it possible im using my camber in the turns but the temp does not get high on the outside becouse of the braking and straights.

 

didn't really follow that.

are you using an infrared thermometer to capture tire temps on the inside and outside?

 

long straights will cool your tires down a bit. (i've never been on a banked straight before though) don't concentrate on tire temps too much to determine your camber settings. although part of the equation, there are many other factors (such as your preference, and the track your on) that should determine your camber settings.

 

nick are you still running the tein basics that are in your cardomain?

 

nah, i've moved on. the tein's just weren't doing it for me anymore. i wanted something that i could corner balance correctly. i'm trying to make the car as neutral as possible, then dial-in from there. i got a good deal on JIC FLT-A2's, so i went with it (yeah, i know, i already feel a rebuild coming ).

 

har har. how do you like them and what are the specs on them (spring rate, are they progressive, etc)?

 

linear springs, 10kg up in front, 12kg in rear. they are 15 way (dampening only) adjustable. i've got 'em set to 8 up front, 4 in back for now as the car seems to like it that way. some people say that there really isn't a difference between clicks. poo on them! if i set the front to 9, the car gets really bouncy (not awesome between turn 8 and 9 at willow springs). they're harsh on the streets, so if yours is daily driven, beware! i don't care since mine's not. i like 'em!

maybe one day when i'm good enough, i may man up and get some kw variant 3's (adjustable both bound and rebound). one day....

 

1. ok... so Definitly 100 percent more camber in the front than the rear on a 350z?

2. if i go to a 255/275 RA-1 with a taller sidewall should i run more camber?

3. how does -2.0 front and -1.3 rear sound, is that about the porportion i want.

 

really interesting that the rear rate is higher. on the Z you see alot of the opposite (high/low)

glad you enjoy them! have fun.

 

Poor damping as in harshness and bounce cost speed and time. DA has it's place in a track enviroment, but the KW's use of progressive springs does not.

 

the model i got is actually for the Z. on the G model, the spring rates are the same. from what i have observed, it's really mixed in what manufacturers give you...to this day, i'm still uncertain why some give you high/low or low/high - in the end, you could always go with spring rates that you choose as most manufacturers offer that.

*EDIT i think the rear springs are progressive on the G model.

 

i knew it was only a matter of time 'till you showed up i keed i keed! doesn't kw offer linear springs? i also heard a lot of good things about the DA setup. TC Kline was offering a really good GB on them a while back, but i guess i didn't go through with it since there was no height adjustment.

i know there are some that say we mere mortals aren't really ready for coilovers, but i like the fact that we could corner balance it and really neutralize the car (and no, i don't care if i can "slam it on dubs). 20 years from now, i'm gonna look at this thread and think to myself, "man, i was such a noob!"

 

didn't really understand that. are you saying the KWs are not good for the track?

and Nick, I think all of KWs springs are progressive, at least in the rear I recall.

 

1. no, not definitely.
2. RA-1's are a different monster all together than the pole positions you have. you can't correlate between the settings of your pole positions to the RA-1's...that's comparing apples to dogs.
3. i don't think anyone here can honestly answer that...there's just too many variables.

i know you must be frustrated at our vague answers, but it's really hard to diagnose things like this on the forums. all we could really do is give you a bunch of different directions you MAY go with, and then you just gotta try it out for yourself.

 

RA1 is a slick? if so, that is gonna completely change what you would use for dampening settings, spring rates and alignment settings...

you are ALL over the place.

and I am not giving you actual setup advice because I would never pretend to be an expert racer or anything. I do know somethings though and try to help
