Wheel fitment whore thread (Stretch/Flush) *NO SPECS, NO POST!*

[rightcoastimports]

quick question/complaint... my car takes bumps horribly.. does everyone have this issue with 240's?? i'm on ksport coilovers with 225/35/19 front and 265/30/19 out back.. i understand with that low of a profile and coilovers it isnt going to ride great but my spec v is so much smoother on the same coilovers and 18's... its just been annoying me lately. plus the roads suck around here.

[silviaguy240]

ksport + 19's = your problem

more expensive coilovers really going to make a huge difference.. even with the same spring rates??

[silviaguy240]

not huge, but noticable. any car is gonna ride rough with coils, and especially when you have no side wall.

True.. its just something we have to deal with. I had 18's before and it felt the same.

YES...not only more expensive ones usually have better damping

they also have better built springs.

this is mine....black car btw
17x10 +15 Rear
17x9 +20 Front
Rolled in the rear
Hammered like a frat bro in the Front

5) As the car is being pushed, push the bat down as much as you can to increase roll/pull.
6) Do this several times until you get your desired pull.
7) Slam the coilovers, then post pictures in this thread... If they're good enough.

thanks man.. so do you use the skiny part or the fat part.

i allready stated the fenders are rolled. they just need pulled

i was hoping to get that part of the the way so i could paint the car. but i guess i will get everything else prepped and thne leave painting until i can do this part. .
my dad is a perfectionist so it will turn out good

waiting for PBM coils and rucas

[markyboi]

the fat part

[J ROK]

How would 18X10 225/40/18 -3.0 camber up front feel? cause under? or still good grip?

[1985zcar]

That's about what I'm running...18x10 +5 with -2.5 degrees on a 225...feels fine, but I don't do any extremely hard driving.

[OBEEWON]

K-Sports come with higher spring rates than most coils = not good for street.

[Z33dori]

it's not the spring rates ....its the shitty dampening

[OBEEWON]

The dampening has more to do with the rebound not feeling every bump.

[axiomatik]

The issues is cheap coilovers + heavy wheels + really short sidewalls + old floppy chassis.

Cheap coilovers will not damp the bumps as well. Heavier wheels will transmit more motion to the chassis than lighter wheels. Really short sidewalls absorb less impact than taller sidewalls. Old floppy chassis means more of the impact motion gets transmitted to you rather than being absorbed by the suspension. Your Sentra probably has a much stiffer chassis, so it absorbs the bumps much more smoothly. Invest in some seam welding/chassis foaming/chassis bracing.

[Z33dori]

wow thats puts everything into perspective.


I never thought about chassis strength being an additional factor.

Usually all the "JDM" coilovers have a really high compression rate on their damping, with relatively low rebound rates.

Rebound controls the damper's rate of expansion, like after you hit a bump.

Compression is what controls the dampers rate of being compressed, which is usually when you first HIT the bump.

Most "JDM" coilovers are underdamped for the spring rates that they come with, thus bouncy and harsh feeling, as the spring's inertia isn't controlled by the damper.

How does that translate to real world experience?

I have Stance GR+ coilovers on my S13, and I have had them on for a year and a half, and have the 9/7 springs on there.

There is a paved section on a road nearby my house, and it's not smoothed out to create a seamless transition, so it's actually a pretty rough bump. For the last 3 months, I've hit it and felt the jarring effects, and hated it.

Upon reading more about suspension and damping effects, I decided to do the opposite of what the normal person would do, which is to turn the damping UP on my coilovers, 1 click on each corner.

Now, not only is it much SMOOTHER when I hit that bump, the car is much more composed AFTER it hits the bump, as the bump is now being absorbed by the dampers doing their job.

I've felt D2s, which are the exact same thing as K-Sport coilovers, with 9/7 springs on them and the dampers turned all the way to stiff before, and it was horrible compared to my Stance, which are still not top shelf stuff. The D2 and K-Sport were very bouncy, very under damped in the high speed damping section. Low speed damping felt OK, but the road was smooth and we were on a couple of sweeping left/right handers, so couldn't really judge if it was just the spring rate controlling the body roll or if the dampers did anything there, but the car did seem to settle down and not feel as bumpy as when the car was being drive at like 35mph and hitting bumps on the road.

So, to answer the dude with the 19 inch wheels that feels his car riding rough. Try to up the damping on the coilovers and see if you feel a difference.


PS - sorry for the novel.

Dude I just bought some FUCA's for my skyline and set it to about -3 up front and i was amazed at how much smoother the car felt when sideways...It was like night and day how much more control I had...but that coulda also been because the old ones were 20 years old and it stiffened things up a little better in the front

Give it shot cuz 240's are easy to adjust anyways

[hotrodv]

now they fit!

what I'm more worried about is the amount of stretch and such neg. camber, when im at full lock am I gonna be hittin rim on the pavement?/maxing out the tires potential for grip? tire coming off the bead from going off track? these are the issues im worried about before I buy brand new tires.

rofl your not gonna die, its been done before. youll just be more worried about hitting the inside of your wheelwells.

We will be doing it with Didderson's car so I will take video!

anyone have pic's of forrest wang's fitment? frickin nuts

sweet thanks man that will be awesome. i will do it when PBM get me my stuff.

i do it

tommy does it

it's fine

feels good

225 in front is money

[J ROK]

^thats the answer I was looking for, thanks

And thank you Tommy Boy.

wheel fitment pics coming soon!!!!

[CrimsonRockett]

My 17x9 +20 once again.

215/45's all around. Stock alignment specs.

Fronts rolled themselves after time.

Rear lips rolled flat.

Does the job for now.

They'll be gone by next month.

So happy.

if its at night we will see some sparks and it'll be awesome!

[k-os]

17 x 9 +12 Fn's all around (originally +20 but front were hitting coilovers so i threw on 8mm spacers all around)

im on 235/40/17 all around

front coilovers are maxxed they are older tein HA's i need new coilovers lol.

[ILoveMyRHS13]

Okay, sorry if this is a noobish question but I have to ask it. I am looking at buying Diamond Racing Pro Series wheels for my S13. I have been looking at a 16x10 in the back with a 15x10 in the front but here lies the problem. In their catalog they have everything listed as "backspace" but it's in inches. I know that backspacing is offset but again, they confuse me because I'm not sure if the "backspace" is how far back the center sits from the OUTSIDE of the rim or the CENTER of the rim. Can anyone help?
