Are you recommending possibly polyurethane bushings in the control arms?
i would think a better stiffer bushing, coupled w/ an alignment that is not “spec” but more of a street/track alignment may help. Oem, bushings will not be hard b/c they dont want complaints from noise–nor do they want a harsh ride. Couple that w/ a “soft” alignment so people are not wrecking the cars, and i could see why tires are wearing badly. Just off the top of my head, audi and porsche are deffinitely lax w/ their alignment specs. Newer rwd lexus are too. By changing some values around on those cars-- you get a smoother drive thats more responisve and more stable on higher speeds (65+) as well as wont eat the tires.
you are in luck. i have a road race 350z here at the shop now. when i put it up on the rack ill take a look at his front suspension so i can visualize it to see what may be the weak link in oem trim.
hell, next time you buy tires, come to my work. i can mount and balance the tires (or even sell them to you-- dealer account w/ tire rack) and do a good 4 wheel alignment using oem specs as well as the tread wear pattern on your old tires. See if that changes anything.
Excellent offer - thanks!
It isn’t Chris Huff’s car by chance is it? Blue?
no it is not. silver z. fixing the diff, blew it up at mid ohio this past weekend.
i actually looked at alignment specs for a z today. you can deffinitely be helped out w/ a different alignment values other than what oem asks for. it almost appears that the front numbers would work better on the rear, and the rear on the front so after seeing the specs, i’d say your suspension is not the culprit, but rather the specs themselves.
