Yup, low stress daily purposes where the anti-roll effect is maximum, the harsh ride minimum (OE spring/shocks retained rather than going stiffer), grip not kept in mind nor the stress the hotchkis can make in hard situations such as tracking.You're telling him to run some of the stiffer bars made for the IS300 for daily driver purposes?
black, perhaps we should just recommend Eibach to all the newer people just in case they get over confident with their stock springs and stiff sways and wrap themselves around a pole. =TYup, low stress daily purposes where the anti-roll effect is maximum, the harsh ride minimum (OE spring/shocks retained rather than going stiffer), grip not kept in mind nor the stress the hotchkis can make in hard situations such as tracking.
Will they effect ride, yes, they reduce the "independent" nature of the suspension, but the ride quality expense is far less than springs/shocks IMO. But if he wants significant anti roll without stiffness, a more advanced more expensive car is whats needed, such as the new STS-V that can change shock dampening in milliseconds.
I have the TRD red/Eibach sways, and have ridden in cars that have the Hotchkis. IMO it didn't dramatically effect strait line smoothness, it'll be fine ride quality wise, IMO the Eibachs are too soft to make a night/day difference in body roll all by themselves.
Don't mean to come off rude, just an explanation of my reasoning, and I used "IMO" a lot as I know how one perceives ride is different than another.
Now if it comes to springs I totally agree with you, Eibach (Tanabe might have comparable ride quality). If he wants to go lower in ride hight then IMO it should be a choice between the Eibach Sportlines or the H&Rs (I dare say that the H&Rs might be smoother than the sportlines, but I'm not sure on that).
