Default Best suspension upgrade for smoother ride

I have no problems with coilovers or any other type of upgrade but I am tired of harshness and lack of suspension adjustability of factory setup. It sucks when my 03 ZO6 rides better than my lexus !!![yes it does] Have talked to Figs about BC coilover kit, and it sounds good and a decent price. Any ideas would be helpful.

For the IS-F I would spend the money on a good coilover setup, especially if you're looking for a "smoother ride".

Shoot us a PM and we can get you setup

I also sell KW v3. The only drawback is the price and the choices of spring rates. But better valve technology (inertial) and more adjust-ability. The BC's are great for a hassle free setup that you will rarely touch. Otherwise you are just wasting money.
I still think they are a drastic improvement for half the price.

KW's are 3 weeks out....I have also heard of some vendors advertising a price increase coming....which is false as far as I am concerned. I will not be undersold mostly because I have zero overhead, unless you count the advertising fees on this forum.

Aren't the new ISF suspension systems designed for better comfort and handling?

It is not hard to achieve given that the OE shocks to this point were so over valved it made the ride feel harsh and gave up performance on the corners when the boat would dive on entry. When I first added the BC's it was better in all regards. Better DD comfort, better cornering, more predictable all around. I still stand by this as the best value for a DD coilover. Not someone that is going to compete in events, but certainly for people that track on the weekends or drive spirited.

I came from a Crossfire SRT-6 and my IS F rides great compared to that.

We sell both BC's and KW's, and we really like both setups, and the OP can't go wrong with either.

But for what the OP is asking for the KW's fit the bill. KW's compared to BC's have superior valving, more droop/shock travel and are double adjsutable. The greater droop/shock travel will pay dividends for smooth driving on typical rough roads and imperfect surfaces.

And BTW - KW is raising prices tomorrow for their entire suspension line.
