Opinions on Alginment specs

martin82 · 10-30-2013, 05:03 PM

I daily my racecar LOL,

As Clint Said, I would go more camber up front closer to -2.5 or -3 it will make a HUGE difference up front, rear just keep it at under -2

I run -3 up front and -2.5 in rear 0 toe all around, I dont get weird tire wear except for on the track obviously outer tire section always wears out more...

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 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?

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.

Thanks.

^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.

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