I think the OP was just asking opinions if anybody had heard of the K-sports. BC coilovers seem to be the way to go, I've noticed other owners liking those.

But I do agree with this statement, excessive modding is a passion that I left behind after college... just seeing ISF's go into limp mode, people's o2 sensors burning out, exhaust too loud, CELs getting triggered due to headers... makes me think modding is a headache. That's just my mentality. 416hp is more than enough to get anyone into trouble on a highway or local street. A front lip that will inevitably get damaged in the long run, is a waste of money IMO, and so are rear diffusers, side skirts... just costs thousands of dollars for just looks...just my opinion. I just can't justify spending that much on those non-functional parts that will make me more paranoid. I think the ISF is absolutely gorgeous just the way it is, and I wouldn't want it any other way. That's my opinion. To each their own, everyone is entitled to their own.

The K-sport look pretty solid, but BC racing is a proven product that I absolutely loved on my IS300. Just keep in mind that at the limits (height and damping adjustment), nothing comes close to stock for daily driving.

I went with KWs on the F just to try different things out, and to be honest, for daily driving I don't think they're worth the investment. If I had to do it again I Would get the BCR coilovers and pocketed the extra $1,000. If you're going to track your car, then you might want to reconsider.

Of course there is better out there for coils, all depends on your budget. BC are well liked in 2IS world.

I wanted to chime in on these three links though... they are from 2006, 2007 and 2011. The company is relatively new, and there is sadly a learning curve (for them at least) and they do have a good handful of poor quality from mid-late 2000's. I would negate the stories from 2006 and 2007 as their build quality has changed since then, as i understand.

The story from 2011 has been having problems since 2008. His coils keep rusting. Says he is from the Netherlands and i would guess he drives in a lot of cold, icy environments with SALT on the road, because those pictures are incredibly rusted. That would happen to any suspension that doesnt have heavy corrosion resistant coating of some sort. So i wouldnt let his story deter you.

Am i defending them because I just got Ksport bags? Not really, i looked into all the horror stories beforehand as well, and it seemed like a lot of haters because Lexus owners can be very biased towards brands, and then there are documented shock failures from years ago, but i have never found anything more recent than 2009ish. A company doesnt get a good reputation without people testing the water, so I took the plunge myself.

Good luck on your choice.

Of course it makes sense. How many people on this forum can attest that they are capable of handling the IS F at it's limits? A hand full of us...one of them certainly not being me. Does any of us need 416hp? OK...I should just say I don't need 416hp, but its nice that it's there. GT3 RS is the same thing...it's a track car for the street. I'm not gonna go hooning around in it, but if I need to...I know the car is very capable. Not saying the IS F isn't.

Some people mod this and that and they have their opinions that it has made it better, but a company like Lexus spends so many millions of dollars on R&D, I feel like I rather just have a NICE/FAST looking STOCK CAR. And if you don't want a stock car and need a suspension downgrade, i mean, upgrade like K Sports, then ......... LOL

And that's the reason behind the GT3 RS...it's bad *** out of the box...no need for all this stuff.

My whole point of my original post was that if you're gonna mod your car...do it right. K sports are CCC (Cheap Chinese Coilovers). You wanna put junk on your $60,000 car...do it.

YEP! Non-functional parts. With some of the fitment things i'm hearing from people, also with the need to run double gaskets and stuff on the headers....ugh. If that kinda stuff is happening, I want to see how long the welds on those things are gonna last before the thing starts cracking. I forgot where the post is, i have to go look for it...but I made a comment their rear diffuser and they told me I should get one because it will make my car handle better...LOL. A $1000 piece of fiberglass/carbon that's never been wind tunnel tested is going to make my car handle better................RIGHT..........

^^^ This post has far left where i was trying to go with it. A simple has anyone tried these before was about what i was getting at.

Darbs242 this thread has taken a detour... but I think the consensus is that K-sports are cheap in quality and should not be used. I have never heard of any ISF owners using them.

Again I'm not a fan of modding, but BCR coilovers seem to be a good budget coilover from what I've heard from other ISF owners. Tein coils and KWV3's are the other popular options which will cost a bit more.

Sorry to the OP for continuing to stray the thread, but reading what Vtothe and Just F Me posted does have a ring of truth to it. I have never once owned a car that I didn't change something. Even though we all know those aero parts don't really add anything performance wise, and aftermarket wheels are really more for looks than performance, it is still nice to personalize your car a little bit. Having said that, reading some of the nightmares about stripped O2 sensors, CELs, limp modes and worrying about warranty issues makes me think that some of the performance mods just aren't worth it. I heavily modded my last car (aftermarket turbo system and all supporting parts) and never felt entirely comfortable with the reliability. I had a OBDII scanner in my car at all times in case I got a weird CEL. I was happy to leave that behind and get into the IS-F, and now I'm thinking I'm going to leave all performance related parts stock.

To the OP (back on topic), you don't want to downgrade your stock suspension setup. You'd probably be better off just getting some lowering springs (Eibachs or Swift springs) if you're doing it for the looks. If you need a more adjustable suspension for track purposes or ride quality, go with something tried and true that has plenty of reviews out there and people that can vouch for the quality. The K-Sports would not be those.

If you search and focus on poor reviews, thats what you'll get. There are reviews bashing BC for having blown shocks just as KSport and any other brand where an individual has blown one:

Just like you can find praise on the KSports:

It's asinine to believe that all KSport coils are garbage because a few reviews online. Most people dont post reviews of products they buy, but the second one fails, they will cover the internet with pictures and stories. They arent widely used because so many car guys and groups are brand wh0res. If they arent XXXXX brand, people will tell you not to get them, simple as that. Remember there can be misuse/improper installation that causes failure as well.

You can find a bad review on just about anything, including your IS-F.

I think the OP wanted to know if any ISF owners had used K-sports on their cars.

Yea pretty much. I doubt he wanted to read over and over why people want to keep their car stock lol. Especially more than one post saying the exact same thing again and again.

I think the original question is answered. The rest of what I'm reading here isn't related to the thread at all. I'm calling it a day now.
