First off, I don't own an IS-F. I test drove one and loved it except for the harsh ride. From what I could tell, that was the only consistent criticism from reviews.

Is there a way to soften the suspension and improve ride quality? Softer springs, softer shock absorbers?

That goes against what this car is. This is not a luxury cruiser but a luxury performance car, the suspension was designed to be stiff for a reason. Sure you could soften it, but that would take away from what the car was designed to be

There are coilovers available out there to diminish the "harshness" of the ride without compromising performance.

 

[poser]

which brand?

Which brand of coilovers are generally considered the best for improving ride?

 

[veerals05]

KWV3 and BC Racing seem to be the most popular around forums. I use BC and they work great! Just make sure you get a good spring rate.

I put on the Tein springs and it feels 100% better than stock, even my GF says its noticeably better ride quality.. and it still handles like a charm

BC is what I run also. By increasing the spring rate you can cut back the damping significantly and improve the small bump ride that is most apparent in the ISF in stock trim. Handles better, the suspension damping curve is more appropriate and the car just eats the road up.

the car is made like that for a reason. you want to feel what stiff is, then drive an evo. if i were to change suspension at all, then i would buy KW's.

maybe im weird, but thats one of the things i really like about my F, ive only had it 2 weeks, but i really like feeling the road and how responsive it is. I test drove a few M3's and they felt equally as harsh/stiff, but for some reason in that car i hated it, and absolutely wouldnt be able to drive an M3 as a daily driver. I feel the F is stiff, but not jarring, i dont know how to explain it, it just feels good and solid.

Hello Fig,

theres any place you can recommend me ?
thanks,

JIC FLT TAR for the ISF is a good coilover choice as well.

I just installed the Tein H, and couldn't be happier. rides much better the stance is more agressive it just looks like the pictures I saw while looking for wall papers of the ISF. I think the stock springs are great for track but for daly driver on not such perfect roads is to stiff.

I really dont understand all the people complaining about the "harsh" riding quality of the ISF. I guess it is all subjective. I have 20" wheels, and lowered with Eibach springs and i still think it rides "comfortable." I guess when i compare it to my Supra with coilovers then it is comfortable.
