R33 Swerving At High Speeds

[CLNSKY]

Hey guys, looking for some input into this issue i've had recently.

Symptoms:

When traveling at higher speeds 80/100km/h + if you take a curve in the road not a corner so no need to brake, when i turn the wheel say 1/4 rotations, the back/car feels like its swerving (As if i was turning my wheel 1/4 right, then left right then left consistently.)

Possible Cause:

The only changes I've made to my car was getting new rears which are federal 595's and still 255/40/17.

I got front and back aligned + balanced.

I got my front "anti roll bar" bolts replaced since the workshop forgot to put them back in after fixing my AC. Probably has nothing to do with this but thought i'd chuck it in.

Possible solution:

HICAS lock bar?

Any help would be greatly appreciated!

Cheers

Colin

Sounds like HICAS misbehaviour. First thing to do though is get it up on a hoist and inspect EVERYTHING.

I've heard of these problems in the past where someone has got a wheel alignment and all of a audden have HICAS problems.

Damn, i'll have to put up the car and check bushings etc make sure everything's tight then see where we go from there.

Thanks guys!
