Alignment questions!

[ekhonda87]

I recently bought a 92 nsx, and after looking at the existing tires, there is extreme wear on the inside of all 4 tires (inside is down to wires, outside tread looks brand new)...
I just put new rubber on yesterday, and am thinking I should do an alignment. Should I have it aligned to factory specs? Or is there another spec I can have it aligned to that will be nicer to my tires (I am not concerned with sacrificing a little performance to have better tread life...)

Thanks guys!

I think it would be a really good idea to have the alignment done. These cars do eat up tire but it's good practice to do an alignment when you put new tires on.

There was a class action lawsuit involving the aggressive alignment spec of the '91/'92 models (they were eating rear tires at the rate of 3k miles). The toe spec was changed in '93 by 2 degrees in the rear only to improve wear (nothing else changed). Fronts should last 3 times longer than rears. Use the search function and type "'91 alignment spec" and you will find a nice article explaining this in full detail. Have your shop align to '93 spec and you should be golden. If you lower the car as most suggest, make sure not to lower it by more than 1.25" as you won't be able to align within spec and will be in the same tire-eating situation.

The toe spec was changed in '93 by 2 degrees in the rear only to improve wear (nothing else changed).

The spec for rear toe was changed by 2 millimeters (NOT degrees), from 6 mm total to 4 mm, and was made retroactive for all years. Some folks who want slightly better treadlife at the expense of slightly less crisp handling have even done the alignment with 2 mm total rear toe, which might be a good compromise in this case. You can read more about the NSX alignment here. But it's up to you to change the alignment however you want; those looking to maximize handling still have the option of having their NSX aligned to the original 6 mm.

Thanks for catching that, I must have been thinking in terms of camber when I wrote that. That's what I get for trying to make sense late at night before bed after a solo 95mi bicycle ride.
