i have a 07 ap2 with 28~29K miles on it with tein s-tech springs and stock shocks.

got new tires all around, alignment and balance done a month ago. After driving it for a a week or two the car felt wobbly on turns, bumpy on regular roads, and not very responsive in terms of changing lanes on local roads and on the freeways; not feeling like the usual s2k i had at all! (excellent handling, etc etc).


I've been wondering what the heck the problem is. I didn't race or went crazy with it to make this happen so that's why im more frustrated about this and wanted to ask you guys first for some help before taking it to the shop.


Maybe my shocks are gone?

Please, any help is much appreciated!!

Thanks!

 

What tires did u put on.

 

falken ziex in the front and fk452s in the rear

 

was it ok before the new tires? it could be the different treads. What size tires?

 

Were you on oem re050s before?

yes

 

ziex 512/912 is a M/S rated all season tire

452 is no where near the dry grip of re050/s02

 

Thats your problem. You went from excellent tires to crappy tires, different crappy tires front and rear no less. Do your car a favor and put on tires that it deserves.

 

The Ziex has a shitload of tread squirm when they're new.

They're also not the right speed rating and sidewall construction for a S2000.

So you now have an all season squishy ass tire up front with a summer only crappy tire out back.

You should have went with better tires.

The alignment may also have not been done correctly.

The crappy tires don't really explain the bumpyness you're talking about unless they were balanced incorrectly as well.

They will respond way slower than your originals and they will have way less grip than the originals.
