Alright, after 2 months of reading whatever I can find off internet and talking to JIC reps and thier dealers, I finally pull the trigger on their VIP coilover for my 02 LS430.
Installation was just like any other coilover out there, I set the dampering setting at the middle for now, I will update more info once I find the sweet spot for myself. Spring rate is 14/7, so far I think the ride comfort is ok, it's firmer than Tein CS for sure, but I feel more in control with these coilover, the car don't roll as much as before, even more planted than the CS.
And like it advertised on the JIC website, I can still drop about close to another inch all the way around, right now the tires are little tucked, but might have to raise the car when I put the bodykit on.
I had Tein CS before and as much as I enjoy and apprciate the ride comfort, it just won't drop to the height I want, and the road feedback is not as clear as the JIC coilover. I know this is just my personal opinion, but I think any kind of feedback is going to be somewhat helpful to another fellow CL member. Feel free to pm me if you have any questions, I will try my best to answer any of it.

 

Gald to hear they're working out for you

 

Post some pictures up to give us an idea of what the coilover's look like.

 

thanks for sharing. this will help a lot of people out

 

I forgot to take any picture of the coilover before the install, I will try to take some pix of the coilover on the car when I get my new wheels next week.

 

Got the same coilovers on my 02 last year. Its slammed too but still rides comfortable. Good stuff!!!!!
