Camber And Caster Questions

Camber And Caster Questions
I've seen Ullose and Team RX-8 say that they were getting 1.2 to 1.6 degrees neg camber out of the front. No matter what I do, I can't get more than .6 and .9 out of the front with stock rims and V-710's, Koni's, and stock bar.
I had a racing company mechanic loosen everything to try to increase the neg camber to no avail.
Do different offset rims increase the negative camber?
Do you sacrifice some of the caster to gain more static neg camber?
I run 1 degree neg camber at the rear and it seems to be well balanced with the low amount I have up front. If I could get more neg out of the front then I could increase the rear and get better overall stick.
Any Help?

No that sucks... Our car had very low camber when we first got it, after a few thousand miles we got more. Could be your car has a tall set of springs, the shop manual has specs for ride height and it is like +/- 1". Order another set of springs and see if that helps.

You will get more camber the lower you drop it.....I had 2 deg of rear camber at minimum in the rear....could get to 3+ maxed out.
Didn't like it there though...it rubbed on everything more than 1" high..
Was able to get 2.5 deg in the front as well...
When i get the new tires/wheels I'll find a happy medium and do the setup from there....drop, corner weight and alignment

don't give up a little, give it all up
max camber occurs at minimum caster on the RX-8; turn the camber bolt all the way out and the caster bolt all the way in
don't say I didn't ever share anything with you, though I'm not inclined to share it all ...

Rather than pulling your car apart go measure you ride height. The shop manual has 5 different ride height specs, so I would guess they have 5 ranges of springs. This is sort of normal for springs. I can tell you on the C4 corvette we raced each spring came in 3 different ranges that were all the "same part #". Nice thing GM did was color coat them so you could get the "stock low spring" just by asking for the right color.
Anyhow if you check the height of your car from the center of your wheel to the inside edge of the wheel arch this will give you an idea if yours are high or not.
Mazda range for 6spd:
14.2-14.5" Low car more -camber
14.6-14.9"
15-15.3"
15.4-15.7"
15.8-16.1" High car less -camber

I take it that this inconsistancy will be pretty common.

Make sure your tires pressure is set per your door sticker. Also they say full tank of fuel when checking ride height.

Let me put it so you East coaster understand.... Make sure you dont got no rounds of wedge in there and take all them spring rubbers out.

But I can keep my stagger, right? Don't take my stagger away, man!

Checking w/ my local Dealer and with Mazda Motorsports shows only one part number for the springs. Mazda says that there will be essentially no difference in springs with this same number.

Go walk around the lot and measure ride height of cars with the same options, they will all vary.

heck I got 1.4 on the front and 1.8 on the back on a stock suspenion. guess I was lucky. Sure handle well.

oh I havent aligned yet since I placed the tein h springs and konis on.
