2012 USA Wheelbase and Track ?

Mon Dec 07, 2015 4:22 pm

Well it was bound to happen--hit a biggas pothole and it knocked my alignment out. i can easily see that the toe-in is off and causing it to pull to the left when the steering wheel is straight ahead. i can see a reduction of range too, as the scrubbing tire is an extra load and using up energy.

i wanted to take a few measurements to see if anything has been pushed back or bent, so does anyone know the specs for wheelbase and front and rear track width?

And for this reason I have a lifetime alignment from Sullivan tire ($190) so I can bring it in when ever I want. They also check the whole front end when they have it up for FREE.

I get worried about the Rim on such a small tire.

Easily found on the Internet

Wheelbase is 100.4" and front track is 55.9" and 54.3" for the rear - If you've hit something so hard that you can *see* the misalignment, it's likely that you've bent something. Your alignment specialist can tell you for sure

My son ran over a partially uncovered manhole (the cover had been pushed aside when flooding from a heavy rain dislodged it) and bent a wheel and cut the tire. We filed a case with the city which has an insurance policy against such things. Their insurance paid for a new tire, new wheel and an alignment

Re: 2012 USA Wheelbase and Track Measured, Toe-In Resolution

Tue Dec 08, 2015 1:32 pm

My google-fu skills seem to be lacking--i wasn't having your luck.

My measured wb was 100-3/8" and front track at 56, rear at 54-1/2", so that seems to compare well with the spec.

The front toe spec is 3 +/- 3 mm, which is an angle of 0.36 degrees, 0.72 max, 0d min. Your eyeball can easily see misalignment against a parallel line.

The tie-rod has an M12x1.5mm threaded end with 6 (hex) flats, so the adjustment can be made to the nearest flat or even to the hex corners ( allowing for increments of 1/12th of a full turn), giving an adjustment resolution down to 0.125mm or 0.005". Just picture the hour positions on an analog clock as an analogy.

So to get kiev in line i had to back out the R tie-rod 4 flats or 1 mm, now i'm back on the straight and narrow.

i'll put the strangs on it this weekend to check my work...
edit---
With the strings i measured toe-in at 3.5mm on L and 2.5mm on R. Starting a new thread about the design of toe-in adjustment.
