Default KW V3, Question

Hey guys, I'm wondering if anyone who has a set of KW V3 coilovers can chime in and lmk how they ride. Honestly the stock ISF suspension is kind of rough imo. I have a 2010 SFP ISF and was kind of disappointed with the suspension. Now I'm in the market to upgrade.

I bought mine SFP 2011 with them on it from a member on here. Actually knew him through a local performance shop.


I did however drive a 2012 at Hendrick Lexus before they sold it. I did notice it was a little rough.


Anyways. I love the Kw3. I would actually look to put them on my is300 if I wasn't selling them. Not sure if they even make them. The ride is a little forgiving. Now remember being low which im not extremely, but it is a little bouncy at times. Handles well around corners. I have never owned coil overs and usually just put springs on with stock shocks bc I cheaped out. I would recommend them highly. If you were closer I would take you for a spin.


Let me know if I can send any pictures or get you any info.

Thanks for the info!


Now I have another question, are the kw v3's specifically for the 2IS any different than the ones for the ISF? Or if someones selling a set for 2IS, i can put those on my isf without any issues?

Spring rates are different because the ISF is a heavier car.

If you can spend a bit more.... may I recommend our RR Racing / Penske coilovers. We just installed a set on bbong's 2012 ISF, and flogged the car on Pennsylvania's "baddest" roads. I think we was quite impressed with how it soaked up the bumps. Turn up the compression and rebound a bit and the suspension is race ready.

Other aspects of the suspension, such as turn in response, transitional response, stability, are simply in another league compared to the KW's. We use much higher spring rates than KW, but ride is just as good.
