Hymlee you may want to think about the oem fuel delivery system. It is not unusual for our oem fuel pump to lose 5-7 lbs of pressure in the higher rpm areas. There seems to be, for some, a lot of correlation between pre mixing and fuel pump problems. Not for others, which further confuses the issue. BUT , the all in one wonder fuel pump assembly may be a trouble spot. So folks need to be sure before they go and tune something that their fuel delivery system is adequete. Or they may end up trying to put the "blame" were it doent belong when they go lean.

A 5 - 7 PSI drop in line pressure (from the nominal pressure), amounts to less than 2% of a drop in actual delivery.
You have to get really low before it gets to be a big issue - especially if you are running with an appropriate amount of "padding" in your target AFRs.

You have to have some padding on a street vehicle.
A bad tank of gas, a really hot, dry day, some anomaly in your driving or just plain bad luck - the effects of which could destroy your motor - can be completely ameliorated by just and extra 0.5:1 in your A/F and 2° of timing, which have a negligible effect on power, if any at all.
I found almost no change in power going from 11.1:1 to 10.8:1.
Of course, if you want to drive around at 12.7:1, that's your business.
That is not something that can be done here in a Phoenix Summer in an RX-8 on 11 PSI of boost.

As soon as I get the T shaped nuts run and the bodys anodized they will be ready for sale. As for different strut bars you will have to look yourselves. On the stock bar you have to drill with a 1 3/8 holesaw the space for the brace to fit through. It's no big deal. On others just see if they stick up over an inch because that is what I've allowed for.
It attaches to ewo of the three shock/spring studs. It does not use the brace studs.
As to the nuts on my brace I don't run a brace. That's how impotant they are. Now a 4 way brace might be worth something. It's just that the only place to fasten is those tiny little studs on the firewall.
This is on the wrong thread it should be on the brake brace one. I"ll move it later.
