Just wanted to know if anyone has recalculated their rig after installing new (bigger) tires? If so how? I went to the Nissan dealership and they said don't get bigger tires and thats pretty much all that was said.

No way to recalibrate the OEM spedo, but you can get a scanguage (http://www.scanguage.com/) and that is programable to calculate for Tire Size I believe.
Unless they are reprogramming the ECM some how there isn't a way to change the speed-o-meter on the new X's.
You can use this page http://www.miata.net/garage/tirecalc.html to let you know how off your speedometer is off.

Would you agree on that tire size muzikman? I like the size of mine, but I just don't think our front end is up to it.
It would omit the warranty worry, some smashing and cutting of the fender, and possibly buying a spare also. (I'll bet the stock spare would be fine, someone add) Plus the geometry, and the handling and mileage. Dawg! I talked myself into it! Anyone want a set of 285 75 16's on 8" Predator al. Rims? Set of 5! JK.

Unless I blow another front diff and they don't fix it under warranty I'll continue to run 285's. I don't think the extra 1" (both width and height) makes all that much different.
I think the front diff problem has more to do with the type of tread over the actual size (in our case). I think the extra bite from the MT puts more stress on the diff / axles than the few extra pounds of the larger tires.

If you know anyone with a GPS receiver, it's easy.
On my old Pathfinder, I used the GPS receiver's Speed display, and made notes of the actual speed when the speedodometer read 30, 40, etc.
For the summer tires I used, the speedometer was high by about 3%, but for the smaller sized winter tires, it was high by 10%.
On my 06 X OR with the stock tires, the difference between the speedometer and the GPS-measured speed is not even worth bothering about.
I did my GPS speed measurements on flat roads, but it will be 'close enough' even on hills. I also once asked a police officer who was setup with laser radar to check my speed, and his result was the same as my GPS.

By looking at it, the set up is just like pony boy's.
They did exactly what pony boy did with his LCA's.
But made it to be straight weld on no fab..
U can get the kit for 2000 including coilovers, then 600 for
the Toy IFS complete kit. I'm going this route over springs
Its only a little bit more! If the page ever works check it out

U may do a little custom fabing but it looks worth it.
