Hey guys...just got my NF210's installed and everything is great! I'm not going to post any pics as everyone has already seen like at least 2 other members here post up pics of their Yaris Sedan with the NF's installed!

But i do have a question.... my mechanic said he didn't cut the bump stops or something like that when he installed the springs? He said they (Tanabe manual) recommended that this be done....but he figured its better that they weren't cut...what is he talking about? Also....is there anything negative or positive about cutting or not cutting it?

Thanks

The bump stop is a rubber "stopper" that goes around the front strut shaft inside of the spring. This piece keeps the strut from bottoming out on big bumps.

When you lower the car, the chance of running into the bump stop is greater and you should usually cut it a bit, to avoid riding on the bump stops too much (which is bad for handling and feels bad too).

After driving for a few days, you should be able to tell if you're running into them, if the ride feels harsh on bigger bumps/woops. If so, just slide up the dust cover, and you should be able to trim the bump stop without having to remove the suspension.

Bump stops NEED to be shortened! Period. Do it asap, your struts will thank you for it. :biggrin:

I'm thinking about getting the same springs. How does the ride feel compared to stock? I'm curious because I'd like the car to be lower, but I do not want to upset the comfort level of the ride. Is it bumpier now or has the ride remained the same just lowered? Thankx in advance.

ok i did not cut my bump stops, and they do not bottom out.
chris, how are the struts going to be effected but not cutting them? please explain this one to me.

im thinking of getting my car lower and yeah i have no idea as to getting which springs for the yaris but i noticed a lot of you ppl out there have the tanabe NFs so im just wondering how much lower is it after installation compare to the stock ones? and since you are living in canada, can you tell me what was the total cost including shipping with the springs to canada. thank you.

Everytime you hit a bump, or pothole, and you "feel" the hit in the front end, that's your suspension bottoming out! You are stopping the range of motion, or cycle of your front struts, by keeping the bump stop at stock length with a lowered suspension... meaning the bumpstop/strut is taking all the impact, and not allowing the strut to absorb the impact or road differences.

I dont know why this 30 second step in cutting a bumpstop is always overlooked, even when is said in the INSTRUCTIONS more then once. :rolleyes:

To the original poster, take it back to who you paid, and MAKE them fix it... or tell them you want new struts, as your will be crapola soon.

Good advice.

Doesn't that really say it all?

umm ya so the valve isnt slamming into the base of the shock/strut body. so the foam of the bump stop takes the hit.....so what. it's not going to damage the valve or seals inside the shock/strut or the body of it, and it's highly unlikely to bend the rod but just hitting the bump stop a little bit.
now if the car is absolutly slammed its a different thing, but the NF's only drop it 1.5" and my car does not bottom out at all.

just stop trying to make it seem like the world is going to end if you don't cut the bump stop.

Hey dude...

Yes the NF's are great for getting the lowered look without having it too low to worry about curbs, and speed bumps getting in the way and scratching up your car...i have the front lip that comes with the Aero package here and it does hit anything with the NF's on. Hmm...i'm going to take some pics of my car soon since another member said - :needpics:
So i will take some....soon hopefully.

Oh yeah forgot to mention that C2Auto hooked me up...so pm him to get you pricing...depends where you live Canada for shipping and all...so msg him..

Since you already know it all, why bother asking questions?

Get on the horn and ask TANABE direct then, ask for Mike. Ask THEM, the makers of the part, why THEY tell you to cut the bump stops. I'm settled at a little over 2" lower from stock, so yea, it does make a difference.

Dont know why I bother giving my 0.02 to fools like you.

this fool here happens to be an ASE master tech, california smog tech, kia master tech and on my way to becoming a nissan master tech, so stop trying to act like you are the god of the yaris ok?

all im trying to say is don't make things out to be more than they really are, telling him how it's going to get all fucked up just because he didn't cut the bumps is ridiculas.
-to the original poster
from my own personal experience in my sedan with nf210's and non cut bump stops, i've had my car fully loaded down with camping gear and never had a problem. with over 3000miles since i put the springs on they are not leaking nor bent - no problems what so ever. don't worry unless you have really bad roads around you.

One of the nice things about this forum is the general lack of personal attacks (flaming). People seem more interested in sharing their experiences and helping each other out than in nursing their egos. It would be great to keep it that way.

I am no master technician of anything but I have lowered a butt load of trucks and have friends in various car clubs that say you need to cut the bump stops the same distance that you lowered it. If you lowered it 2 inches cut 2 inches if you can. Sorry El Jefe, but even Toyota couldnt tell me half the stuff that I have read on here. NOT saying this about you, but all the Toyota dealer I got my Yaris from knows how to do is read a manual for sopmething they have no idea what they are talking about.

hi guys, i'm just about to buy my first car... which is most likely to be an 07 yaris sedan. i've been doing some slights mods in my previous car but i'm from another country... so i'm not sure if US practice do this as well:

wehn you want to lower your car, some shops offer to just clamp your stock springs by 1inch just to give the car a lil bit of lowness. do you guys do this here as well?

it has definetly been done, but as to if it is safe, or going to give desirable ersults...well, just imagin, on a brand new car, why not spring for a sent of proper lowering springs? :)

but yes, it has and is being done here...


edit: hopefully not to any yaris though ;)

johnny five. thanks for replying... but lowering springs tend to be stiffer than stock springs... i'd like to have a lowered spring that rides as comftable as a stock spring. i dunno if there is such a thing that exist though :D + i don't want to be shelling out money for another set of springs :(

Hi Jeff,
I got my car lowered with Pedders Sports Ryders and the ride is actually as supple and smooth as stock, perhaps even more so. Handling is also improved slightly, and the stock shocks don't seem underdamped with these springs.

i've lowered a SHIT LOAD of car, trucks, bikes..whatever i get my hands on, and all im trying to say is it's not the end of the world if you don't cut the bumps on a 1.5" drop, and from personal experience on the EXACT subject i know this.

Hey thanks all to the input. Especially Chris and Jefe...didn't mean to cause probs between you guys...but i value both your input since you're both experts....thanks for the advice. Now that i know what to look for i will see if i can feel what you described when hitting bumps and if i do i will get the bump stops cut a bit. Hmm...as promised here are my pics...hopefully they show up....heh heh notice the Toyota TRD badges... :wub: heh heh totally rice...but i like it hahaha...it will be TRD soon...TRD as in Tanabe Racing Development! HEH....

I don't know if you can call 2 cars a lot but I'd rather leave the bump stops as it is. It's there for a reason. Last thing I need is to replace the shocks coz it's bottomed out and f'ed up the shocks even if shocks are cheap. Then again, roads here are shite and you have to pick your lanes with the least amount of bumps and lumps. All part of the fun of driving a lowered car. :iono: If you bottom out, then you're not driving on the right roads or your car is too low.

there's really no need to cut the bump stops for the NFs...for springs w/ more drop like the DFs, its recommended that u cut them

YES! Absolutely, the Tanabe NF's are more designed for comfort, from what I've heard, they don't hurt the ride at all, Tein H-Techs are designed for the same thing and I understand a Yaris application will be out soon. The other brand I've had good luck with is H&R, the H&R Sport springs lowered my I30 just enough to eliminate the wheel gap and take the floatiness out of hard corners and still give the ride comfort I expected, I don't beleive H&R has, as of yet, announced a product release for the Yaris.

And on another note, although many have not experienced any problems by not cutting the bumpstops, I can't believe that Tanabe would suggest this for no reason at all. The remaining bumpstop after cut should be plenty to keep the strut from bottoming out, where as, not cutting it may, on bad roads, cause the bumpstop to be struck which not only feels VERY uncomfortable, but can cause damage to your suspension if it happens enough, due to the jarring shock, and not letting the strut complete its travel cycle. There are probably valid reasons for cutting them, and probably valid reasons for not cutting them as well, it may be dependent on the quality of your local roads. Rather than resorting to personal attacks, maybe we should just post our reasons for our view, and let the buyers and car owners decide.

When you have suggested/shared/written a how to explaining, etc... only to hear shit from the people that dont agree, it tends to get under your skin a little.. Maybe thats why my reply may have sounded harsh? :iono:

Jeff being the "master tech" he says he is, I respect his "opinion" but I will put my money on the advice of the company that DESIGNED the system first. If they say to cut them, then a cuttin' I will go. Yes, maybe it's not such a huge deal when lowering a car an inch or so, but when dealing with the DF210's, that put me over 2" lower, its needed. Period.

Tanabe is a manufacturer that makes aftermarket suspension components, the NF series of springs are lowering springs that are tuned for comfort, they lower the ride height and improve handling without sacrificing comfort.
