Since I bought my Z new 7 months ago, it has never felt planted on high speed turns. The rear end feels mushy and sometimes breaks loose, especially on any pavement less than perfect. And don't even think about applying the brakes going into a turn at high speed, it's just makes it worse, no matter how mildly they are applied. The cars rear acts like it wants to come around and meet the front end. It's most noticable on fast sweeper turns, more so than ultra tight slow speed turns.

Kinda feels like the car has really tall profile tires or something, like off of a Jeep.

I have Hotchkis springs and now I'm running 19" wheels (245 and 275 35's) and it still acts the same way, as when it was bone stock off the lot.

Next summer or Spring I want to do something about it. What are some cost effetive things I can try first?

I was thinking of Hotckis sways but I admit I don't know much about sways and have a lot of reading up and searching to do but i would like to know from from you guys what i should look into upgrading first.

In the end, I want the car to handle like it's on rails.

 

1. what tires are you running?

2. what tire pressures?

3. what are your current alignment specs

Don't throw more parts at the car just yet.........you might not need them

 

Tires are Nitto 555's (245/35/19 and 275/35/18) NOT the racing 555's.

Alignment specs where as far as I know, set to the factory specs when the Hotchkis springs were installed.

Don't know what the PSI's are at since I only put about 200 miles on those tires before it went back into the shop but when I had the stock 18's I was running 36 PSI cold.

With these wheels, tires and springs it handles pretty much the same as when it was bone stock off the lot.

 

That's really odd...I'm going out on a limb here, but maybe your rear shocks are busted? Does it act the same way turning left/right?

 

gotta check your tire pressure for sure - as well as your alignment specs. Print up those #'s and we can go from there. My guess is that is where your problem is
