SC430 handling question
I just bought a 2002 SC430 last week. Yesterday I took it out to drive to work for 50 miles.
My observation is at highway speeds, the car wonders a bit so that I have to use two hands to hold the steering wheel to keep it straight with minor correction.
I know the steering wheel is kinda loose and light which doesn't help at all. Besides the coilovers (which we have to wait for another month), will a front strut bar tighten up the front end? I have a front strut bar on my 2001 Nissan Maxima and it really tightened up the front quite a bit.

Not sure about alignment. The car doesn't pull to either side.
My Nissan had the same issue of wandering/loose front end before I put in the front strut bar. That's why I am thinking along this way.

i just alligned mine at firestone 179.99 for lifetime allignment and its much better and at high speeds 50+ MPH and low speeds im driving straight as an arrow. It might be worth checking that also make sure your tires are balanced correctly and that none of the rims are bent.

Hmmm.. Im wondering has Lexus updated the steering and suspension on 2006+ facelift?
My SC (2010)'s steering is quite stiff and communicative, and the suspension is not too bad either.. the car handles well and feels planted up to the limiter (not that i have been there ) - BTW, limiter on ME spec is 175MPH

There was a change to the front suspension system in the 06+ update. Most folks notice a much smoother ride with an 06+ compared to a 02-04.
However, in reading jzwu (how does one pronounce that, by the way), my first thought is this...
Are you running Run-Flat tires?
The runflats are notorious for making the car a both a) fidgety on the highway and b) makes the car tend to follow the seams in the road (which don't always correspond to the lanes)

Funny thing is the previous owner changed two new front tires to standard tires (245-40-18) and the two rear tires are still Dunlop run-flats.
Do the run-flats make a difference on the rear too? I am going to do a road force balance.
