Alignment questions
 

I have a 2012 grand sport convertible I'm buying new tires for it on Monday what are the best alignment for tire where does anybody have any specifications on this I don't track the car so I just want the tires to last longer than 8000 miles

I don't have it, but do an advanced search on CF for "pfadt street alignment."

:thumbs:

Does this apply to the GS only or I can use them on my base model too....? Thanks

Sounds like you just drive the car on the street and aren't going crazy doing hot laps around the clover leafs. I've found the best place to go for an alignment is NOT your local Firestone, Goodyear, neighborhood shop or even the local alignment guy. Find a good frame shop in your area that specializes in fixing cars with bent frames. They typically have the best equipment in town and know for sure what they're doing. As far as the Pfadt specs go in your case I'm avoiding those and let the frame shop do their thing to the stock specifications.
Good luck!!!

Better Pfadt sheet that does not give them a ton of wiggle room, and its the "Pure Street" alignment you want to have the car aligned to,

This is how mine is set.

If the alignment guy really knows his stuff, take him your old tires (marked with previous location) and he can see how the wear is for your style of driving.

I'm at 124K miles with the OEM factory alignment and have had perfectly even wear on every sets of tires. Apparently, my mix of daily driving and performance (aka spirited) driving fits what the factory settings anticipated. The factory assumed that a Z51, a GS, and a Z06 were going to be driven more agressively, which is why they usually need realigned for the everyday driver.
