I'm looking for a definitive answer to the relationship between front and rear camber for the Miata. Should there be more camber in the rear, or more camber in the front when compared to the other end of the car?

I've always set up my AWD cars with roughly 1* more camber in the front. The race shop that's going to align my car this week is recommending that I go with 1* more camber in the rear of my 99 than in the front.

Any advice based on experience?

welll, since I just read your other post and I know Dave is doing your car.......

Take his advice. It is hard to get enough front camber if you drop the car as low as the 99 will go, with the extra weight the 99+ carries more camber is usually good everywhere.

Okie dokie then. I figured he knows more about this than I do. I have no experience with RWD cars. He's not going as low as it can go because I will be driving the car to/from events this summer, so I think I'm going to be camber challenged anyway.

I recently installed new LCAs, the 99 shock hats and did a full setup following JDs guide. No trouble getting 3* up front. At a recent track day I've never felt the car handle as well as it did. Camber settings are 3* front and 2.5* rear.

I used to run 2.2* front and 2.7* rear. JDs setup is way better.

I cannot think of a single time I ran more rear than front in any MX5 any tire.

As the guide says, TEST!!

Crazy setups that are always loose (big rake, rear on stops, no front bar) is another story but I've not raced much in that trim.

Thanks Jim. Dave@DWW said to say hi, and mentioned something about lobsters that I've now forgotten ;^)

There is a good write up on miata.net about the dynamic camber changes as the suspension travels. Its some good data to take a look at.

With my friend Jyri Virkki, I have measured front and rear camber curves on my '91 and also an '06 NC (but not an NB, although I expect they are nearly identical to the NA). The dynamic relationship is also interesting to look at as Lucky_Kid mentioned.

http://www.virkki.com/jyri/miata/camber/

The page takes a few seconds to load because it has a couple embedded javascript apps. You can use the arrow keys to find your starting ride height (our chosen method is from the center of the wheel to the lower fender lip), starting camber and then see how it changes with suspension movement.

For all competition alignments, I have had the most success with more front than rear camber. This is autocross and track driving. Pyrometer testing is the best way to know for sure - aim for a bit higher inside vs. outside tire temps.
