what tire pressures do you usually run Jerrett?
The 7/8 bar on my NA did wonders for my oversteer.
At least with my style of driving, I have a very nuetral car with FM 7/8 bar in front, stock in back, same tire pressures, and all shocks (Koni Sport) at the same stiffness.
YMMV, especially if you have more power than my 1.6. You are welcome to try my car on a fun run if you let me know up front so I don't pack it up.

Yeah, POS just doesn't drive hard enough to really stress the front bar...
I tore the swaybar mounts out of the frame on my '99 after a couple of seasons with a 1" FM front bar. I replaced my stock mounting brackets with the Mazdacomp/AWR Racing brackets and never had another issue. As far as I know, my car is still being autocrossed in Houston with these brackets (which are SCCA Stock legal, once you modify them for clearance). The only thing to beware of with these brackets is that you'll need to either trim the lower radiator supports or the brackets themselves to prevent interference on the NBs.
lugnutjon also tore his mounts out of the frame on his 10AE with a 1" FM bar. He had the stock mounts rewelded, them tore them a second time. After that he ordered a set of the AWR brackets and had no more problems.
This was actually a pretty common problem on the NBs when autocrossed heavily on R compounds, POS's experience notwithstanding. In fact, it was so common that the SCCA issued a clarification specifically addressing this issue, because it affected a large percentage of the top cars. Prior to the ruling removing the old brackets (which are plug welded to the unibody) or welding them back together was technically illegal.

Unfortunately, this bracket isn't the weak link on the NBs. The problem is with the flimsy piece of bent sheetmetal that these brackets bolt to. That piece tends to fatigue due to the cyclical loading of the sway bar. Over time and with enough loading it will tear, usually starting on the inside.

I personally found that my 93LE didn't have any oversteer at all and was very neutral to start. I did find the front bar cut down on body roll and helped the turn in become much faster/sharper. I run a similar setup to jrj512 (7/8" front bar, azenis, but different shocks)

Jerrett you only say I shouldn't run R comps because you know I'd beat you.
:)
Ok well, I guess I will get the RB front bar without bracing then - or should I get it later?
And I hear the Azenis gain 5psi or so when they get hot, and I hear they still require a spray down every 2 runs...but I never see anyone out there spraying tires, so is that grassroots motorsports bs? Or does it just not matter that much.

Hey I won the dixie tour, oh wait that wasn't me.....
I also think the collars help keep everything in place, did you have the spacer collars on your bar?
Andy H. had a post on miata.net talking about the importance of the spacers and the previous owner of the POSIII had the spacers on the car.
YMMV
I'm running a 1.125" hollow RB on my car with shimmed (washers as spacers) front brackets. I didn't realize the problem until Mr. Hollis talked about it.

So, for my skill level, should I really worry about spraying them?
And just to keep the ball rolling...
How long do the Azenis typically last on a daily driven car?

So do those shims do basically the same job as the "hardware only" bracing kit from TDR; the aluminum blocks for the mounts.

Is there any information on the differences in performance between RB 1.125" hollow bar and the FM 1" solid bar at the various settings? If I am reading things right, it looks like you can get the front and rear SET from FM for less than just the RB front bar. What makes the RB worth the extra coin? Does the RB offer equal stiffness at a lower weight or something?
I know it does weigh less.
And it's red.
Here's a link to those hardware only mounts btw:

http://www.fatcatmotorsports.com/ they have a cool spreasheet deal, looks like it's taylored to the NA.![]()
I highly doubt mine will last a year. I probably could have gotten 8 months before I went bald on the GForce Sports.
So I'd guess 5 or so with autocrosses and street driving every day.
