I know about the 5 lug rule and will not be modifying the car nor will we be installing other OEM Mitsubishi components as it throws the alignment so far off it is ridiculous all the modifications that have to be done to get a straight alignment. I doubt this car will ever make it to Ohio. We are not looking for any certified records, just trying to go as fast as we can afford. We will run open lug nuts and use safety wire on top of that and hope that we have showed we are willing to make an effort for safety. And this car will likely not see the salt flats either. It has been a drag car for over ten years and slowly converting to a pavement LSR car over the past three seasons.

I have read your rules Mike but, my problem is what you allow and what the manufacturer recommend is on two ends of the spectrum. This is mine and my driver's lives at hand here and we fully believe we will be at these speed thresholds with the new setup and want to make sure we do our part to be safe.

What's Reichen run?  He's been over 230.  His car doesn't look like a monster truck.

Reichen uses drag radials (not sure which brand)... and yes, he's been 237 in the mile (at Ohio, no less!)

Converting to a 5 lug pattern is not too difficult. My rear hubs are from a Porsche 996 and although it had 5 lugs, they were metric and the bolt pattern was 130mm. Only Porsche racing wheels would fit and they were not available in a decent selection of rim widths and back spacing choices, as well as being $$$.

I had the hubs drilled for five 5/8" UNC studs on a 5" diameter bolt circle. This way I could use circle track wheels- cheap and available in many sizes. QED.

Please contact me privately and we can discuss your issues one-on-one.  While you are correct, we base our limits on seven years of experience running standing mile events plus twenty years of experience in Open Road Racing events, where Unlimited cars (mine included) ran at sustained speeds of over 220 mph for up to 130 miles.  If you thought it was tough trying to get tire makers to talk to you about Bonneville, imagine what they do to Open Road Racers who call them about tires!  In both types of events, tire failures are the #1 cause of mishaps, so we do not take tire speed limits lightly.  So far, we haven't seen a single tire failure at a Mojave event.  FWIW, the R7 has proved to be a rock-steady performer in standing mile events, and we have a number of participants who have logged many, many passes over 200 mph on them without a mishap.

Converting the hubs isn't a problem on his mirage.

The road race type tires are the way to go. Plenty of sizes available from Hoosier. Unless you can find some smaller discard nascar tires.

I recall a carefully handwritten note in my (2nd hand) Latin phrase book, from 50 odd years ago "Latin is a language as dead as dead can be, it killed the ancient Romans, and now it's killing me!"   "QED" is so firmly embedded in my skull it has probably been passed on to my grandson in my DNA.
