We have received one order for an un-engraved cross-brace.

Here is how we are handling it. We are taking NO MONEY at this time, while we wait to see if ten folks really sign up for one. If 10 or more do, at THAT time we will request a 50% down payment, then we will go to manufacturing.

Please remember we do currently offer an unfinished version (for $30 less) that is specifically so you can finish it any way you please. The engraving is not that deep - you could take a skim cut across the top and you'd be good to go. Or sand it with a belt sander. Or fill it with JB Weld, sand it and paint it. All options that would work. The un-finished models are in stock now.

I answer:

From Pete Dolfis - height of front lower frame brace off the ground when installed. The aluminum item on the far left is one of our protection plates.

Thanks Pete!

Consider that the frame brace is much less expensive than either the alternator, the air conditioning compressor, or the oil pan that it protects.

Now we are talking street use, but on the street, you will never see the forces that can twist the frame, and for the track, sure it can protect you from an alternator breaking... maybe.... but the extra ride height is NOT a good thing to do this. if that was on my race car, it would not survive down the corkscrew or "hill" at T'hill. i just barely touch the oil pan in worst cases.....(no touch anything generally).......to clear that bar, you would need 1" higher ride height and that is NO good for 928 racing... i can calculate the loss of G forces possible and that is not significant to protect yourself from an "off". also, if you are good enough to twist the frame that much, you will be good enough to not have an off that could wreck your alternator.

and your answer was a 16"" breaker bare effects on wheel forces transferred to the chassis.

carl , your calculations of off a bit, expecially when the wheel is sucked up by 5" into the wheel well in Hi compression turns. (to create the gs needed to twist the frame rail)
this is a lot of theory.... interesting to look at.
but this picture is a street car on street tires and small ones at that. there is maybe a possibility that he is seeing .8g's. what is that effect compared to you pulling over "2 gs" ? you are also not incorporating the angle of the force of the turning wheel to make the turn in the firrst place. this vectors the force dramatically rearward
all in all...... I dont see the problem, and again, been racing the platform for 20 years now. as soon as you find a way to actually capture twisting values, its all speculation. your tests of "bending the cross" bar indicates that you are reaching when you are calculating the offending forces. you have to understand where they are coming from first before you can calculate and assess them, right?

So, you calculate a 16 breaker bar twisting on the chassis. Ok then.. what do you think the lateral forces of the car in a high speed turn would be pulling 1 g. (above the street car show, but lets go with it) oh, doesnt the wheel impose the same forces when the car is under braking.. how about in the air on a jack and then lowered. there is 800lbs on each corner.. it doesnt move now make a 1g slow down. ... more than 1200lbs on each fronnt wheel ..... hmmm frame doesnt move or twist. that frame rail is part of the unibody which is a box that goes from the bottom to the shock towers.
But, ill humor you......take that 16 " breaker bar and put the g loading forces on it and see if the frame moves or twists..... carl, you are reaching if you think it will . and not to mention, in that kind of high g loading turn the wheels are turned and the forces are not directly tortional. also, there are so many connection points of the uper A arms as well. you are talking about twisting forces on a 3" box steel rail about 12 long because it attaches to the cross member for the box.
good luck trying to see if any forces generated by that 16 lever arm can do anything significant to camber under a 1 G turn

we have documentation of carls HP.. 700hp
we have documentation of his racing speeds and times... equal to spec miata
we have documentation of my racing times and speeds. 10 seconds faster than spec miat records at any track ive visited and that about 10 tracks.
this is not a comparison of drivers, its a reality check to see which car is experiencing more g forces and seeing problems in doing so. I have not seen wild camber changes, eccentrics that move, etc. my car is firly planted and the only time it has ever had a problem lifting a wheel or makng a LSD slip, is if i lose a front sway bar (which has happened a few times)

what holds water is if im a full 10 seconds faster than car at all tracks( sans HP tracks like road america where we are about the same ) i will be pulling more Gs, even at road america, becuase the HP straightline speed is so much higher .
did you see the video of the him vs the GTS2-3 car ? he pulls out and blows by him.. i dont even pull that much on those cars. i get my advantage on the turns , i.e. G forces!
what doesnt hold water is your "assertions" hill climbs and 700hp, doesnt assure you to be able to pull g forces. I know, i instruct guys every month that have 700hp and pull many less g forces than a miata . not uncommon at all.
anyone that races or has more than 1 or 2 track days under his belt knows this.

Pre-order placed. Thanks for the option.

Should we be dividing Kibort's post count by 3 since he posts thrice to everyone else's once?

Carl Fausett

Thank you for your order.

We now have 2 orders for the un-engraved cross brace.

Carl Fausett

So he continues to hammer away... since your quoting your best times, would it not be more correct to use my best times?

I keep telling you (and you seem to ignore) that we have been sorting the car out this season with the new transmission and gear ratios. I have not been turning my best times this year. But, we are getting faster...

We are WAY faster than Spec Miata - that's an insult.

Here ya go, Mark:

results from last weekend at Mid-Ohio. Go to the results of Day 2, Thunder Contingency Race. There you can see a nice list of who I was faster than, and who was faster than me. I crashed out (my fault) on lap 3, so I was still getting quicker - but thats no excuse.

Powder coated all them pipes and the X member. Black hides most of the badging and marketing, plus looks great IMO.

Carl Fausett

I think the black looks very nice! Hard to keep dust-free?

Carl Fausett

Now I have 3 orders for an un-engraved version.

jwyatt8171

Pretty easy when I haven't driven it much at all since I put it back together.

Carl Fausett

Well, it looks great. Good job!

Mark Anderson

Good Luck with that
