This car handles very poorly compared to a Tesla Model 3 and M340i. It's nice when you come from a Corolla or Camry it handles good but they haven't changed much since 2014. The handling I am specifically talking about is the body roll of the car, it's a significant amount. I was looking at coilovers and I saw BC racing coilovers (~$1000-1200) looks like a promising option but can anyone speak on it improving body roll and handling? I am not looking to slam it on the ground, probably keep it stock height or a tad bit lower. Can anyone with experience on these coil overs touch on this please?

 

I can't give input on the BC Racing Coilovers as I've never owned them. I know they're popular but not sure how many IS owners use them. I'm using Eibach Pro Kit springs and they have reduced body roll for sure. It's a mild drop about 1". I would think the coilovers would be better in many instances as it will give you the option of adjustment in height. I don't think you can go wrong with the BC's as they've been around for some time and they will resolve the body roll. I'm sure others that have experience with the BC's will jump in to help.

 

RS-R Coilovers and they make an active one if you have AVS. Add some tom’s racing suspension bars. Upgrade your brake pads at least and add michelin pilot sport 4S or S5 tires

 

Rear sway bar a definite noticeable change to the chassis from Eibach.

 

do you have to drop the rear subframe to put that in?

 

I run the BC racing coilovers on my LS, I like them more for stance then the handling, there are better coilovers for performance but they also are more money. If you are not looking to lower the car and mostly concerned with roll, given you have a base is, I would look at upgrading the LCA's to the aluminum brackets that the F and F sport models have and sway bars will help with the body roll, Even the F sport sway bar is thicker.

 

I have a 2025 Lexus IS350 F sport. Which are other better coilover brands besides RSR?

You have to lower it enough to be able to put a ratchet on the bolts. Don't have to completely remove it to the ground.

 

If it's for a 2025 350 F sport, top tier would probably be the Penske (your signature said 250 non fsport) You could just go with some swift springs, It all depends on what you are looking to do with the car.
