when you lower your car it naturally creates negative camber, normally this can be corrected by having an alignment shop adjust the camber, but our cars don't have any camber adjustment from factory. so you can get a megan camber kit to rectify that, its not needed. its just so you can get more life out of your tires

also, it doesn't matter what order you do the sways/coilovers in. I'd do the sways first since its the cheapest and takes 15 minutes to install if you know what your doing, or half an hour if you don't know what your doing.

 

hm... yeah maybe ill just get the sways and wait on the coilovers. whats the lowest i can lower my 2is without any tire rub? i have stock tires still...

 

haha almost complete slam. camber kits are only like 180 bucks. and i say do it all at once cause your gunna be under your car anyways. and on bc i think the popular spring rate is 8k/10k or 8k/12k.

 

Since you are planning to go fast around corners. I would recommend giving it at least 1 finger gap so you don't rub hard.

I for one would get Front and Rear sways for the 250 or 350, as it looks like an error in the brochure. The sway bar thread has plenty discussion on this.

 

i just read a thread about a guy who lowered his 2is and is having severe problems with tire wear now. he didnt get a camber kit. i think his is an 07 though. ive got a '10. what are the chances of something like this happening? and i just got refunded money because the sales guy said the bc racing camber plates wont work on my car. is this true?

 

How committed to driving fast around corners are you?

The best way to spend your money is on driving school, not playing games with a suspension you admit you don't even understand. So far 100% of the advice in this thread is misguided at best and just plain wrong at worst. You'd do a lot better for your money modifying the driver, not the car.

 

^ +1 I couldn't agree any more,
truth of the matter is if you can drive the car stock through a track taking corners at speeds faster than you'd ever hit on the streets you'd know that modifying the suspension for your exact needs would depend on your requirements. As Lance mentioned, most people here that talk about custom coilover spring rates / valving wouldn't know what that would do for you on the track. For that matter most coliovers here are used for purely cosmetic purposes. So you'd really have to ask yourself where you fall in the pot. If you really must have something that can handle on the track per say, contact BC and KW, I'm sure that they've worked with people who own 2IS's and run custom spring rates for track purposes. So any advise on that I would leave it to the companies or members who have experience with custom rates.

I agree that a majority of the owners here use their coilovers mainly for cosmetic purposes (ala achieving the VIP look) and not for the track. My personal recommendation is to get the Lexus F-Sport Shocks/Springs/Sway combo along with a good set of sticky tires.

The kit has already been extensively track-tuned by Lexus/Bilstein so it doesn't need to be customized like coilovers, it is an OEM product, the ride is conservatively lowered to the ground, and the upgraded suspension feels firmer/planted to the ground without much sacrifice to the ride quality. Google "Lexus F-sport IS250" and you'll find plenty of reviews/test-drives which state that the F-sport IS handles comparatively to the IS-F.

You can get all the needed parts thru the vendor Sewell at discounted prices since you're a clublexus member and be below your $1700 budget if you find an independent shop to install the parts for you instead of the stealership. Just providing another option for you to consider.

 

^^, Agreed the majority of the coilover purchases for IS are for cosmetic reasons, at the expense of degraded ride and handling (not to mention increased noise transmitted into the cabin). The main advantage is realized in parking lots at zero mph.

 

well, dont get me worng, im not taking this car to a track. actually, there are 0 tracks in HI. i just want to know so that i dont eff it up. ive never worked suspension before and im nervous is all. totally agree though. upgraded sus or not, if i dont know how to drive the car, it wont make a difference at all. but im not interested in racing it really. im just worried is all. i think i did alright with the bc racing coilovers. and ill just keep a close eye on my tires. and if i see any disformation ill let you guys know and try to find someone to fix it. I just want to know what my options are. i dont want to run into the burning house without a fire hose. know what i mean?

 

no matter how good of a driver you are, when you huck turns in a stock ISx50, your get soooo much freaking body roll that when you come out of the turn you'll whole car rocks back and forth. put on f-sport the sways, at least the rear its like 150 bucks

 

oh yeah. most def bro. im taking the advice you gave me. only thing is that i dont think im going to worry about the camber kit from megan. ill worry if i get excessive tire wear.

 

You'll get ridiculous tire wear from doing unnecessary burnouts/donuts
I'm dropped on H&R springs, although a mild drop, not much noticeable uneven tire wear tbh.

 

lol i think getting the rear sways and call it a day!!!

 

Once again, proving the untrained create their own problems. If you'd been in a 2IS with a pro driver, you wouldn't even begin to say this. And body roll control is highly overrated. There's nothing wrong with roll as long as it's predictable and consistent.

When you know how to feed inputs into the car, most of these supposed issues become pointless to discuss. If you drive like you've got meat fists, sure it's going to be pretty poor. If you know how to drive smoothly, you'd be amazed what a bone stock 2IS will do.
