worn out or is it good?

[Guest Anonymous]

ok i took a turn in my z at 75(the turn was marked for 50) and my exit speed was 80mph, but the car did not feel stabil, it rocked from side to side and i had no feel for the road. i want to go fast in a straigh line first, then i'll work on the sup., also will lower profilr tires help with the rocking? i plan o getting some "snowflake" turbo wheels and putting 215/60/15 on it or 225/60/15 if they will fit.

The rocking you experience can be a few different things. Likely it is either poor struts or worn bushings. The struts are easy enough to check, push down on each corner of the car one at a time and notice how many times the car "bounces". With good struts there should be almost no bounce at all, with really bad ones I've seen up to 4 rebounds.

 

Bushings aren't quite so easy to check, but a good way to do it is visually. Check the rubber suspension bushings, specifically the sway bar end links and frame mounts for rips, tears and overall condition. I'd recommend getting a urethane bushing kit for your car anyway. Even if your rubber mounts are in good condition you'll notice how much the urethane kit stiffens up the chassis.

 

One other thing you might want to do after all this is get a shop to check your alignment. (recommended after replacing bushings)

 

The tires/wheels seem to be somewhat surrounded by myth. Larger rims isn't a huge change in handling, though the rice boy fad etc seems to have made this myth into even more. Yes you'll get a gain with bigger rims and smaller sidewalls, but from the sounds of it you can find more effective ways to spend your money on upgrading. If you can, do both!
