I have been playing with the rear suspension in CAD... Once my Z is down for the winter, I have intentions of playing with some brackets to change my rear control arm angles to reduce compression camber. I wasnt sure if it would be of any benefit to the track racers or just drag racing / street guys. Once I have it on jackstands for the season, I can take the rear springs out and play with different pivot locations and watch the compression specs

I like -3.0 F and -1.8 R, 0 toe all around.

I see what you're getting at here, only way to know is on track testing with a pyrometer. How much of a curved reduction do u have in mind?

This is what I run on my 370

O I know. Have to write down everything and get a nice plan together what to attack first and how, then move to toe so you have a nice sequence of events to get to your track numbers. You could also spend $200 on this I just saw someone post.

Quicktrick Alignment | DIY Alignment, wheel alignment, toe align

There'd be no guessing. Just attach to wheel and done.

Ok, got the Nismo aligned today. The front for both sides is camber -2, caster is 6, toe is zero. The rear both sides. Camber -1.7, toe is zero. It's raining now. So I can't really try it out. After today. I can't do anything for 4 to 6 weeks. Having surgery on my foot tomorrow.

Thanks' for all of the input guys.

Good luck. Hope it isn't bad. Foot surgeries are the worst to recover from.

Opinions please.

Just wondering, how did you come up with a caster of 6? Is that the best for our cars ? I'm taking notes for autox next year.

From something I read. To help with turn in, and camber when turned.

cv129 · 11-01-2013, 09:36 PM

^wait, on the caster, u meant positive 6 or negative 6? I thought positive caster helps create negative camber when front wheels are turned?

Edit: Just reread, disregard my original post.

Now next question...from the link below, it shows OEM nismo has +8 degree caster? Or is that not 8 "degrees" but some other unit of measurement?

OEM Nismo Alignment settings?

In that link. The chart shows that the stock setting is about +5deg. So I'm trying +6 for now.

I was referring to the post by Fontana Nissan, caster 8.17. But remembering what Nismo09 said on caster adjustability with the SPL arms maxing at about +7.xx, I guess +8 stock is not possible. Thx and good luck with the surgery.

I don't know where they got the 8deg caster from.

The surgery is done. So now I get to kick back and watch BBC Top Gear, and all of the racing I can get.

Thanks.

Rear camber around -1, fronts around -2 should be great for both. That's what I ran on my car.
