Konig Oversteer 18x8 + 18x9

[Gutterboy]

been hunting the forums on this topic for a bit now and playing with the auto fitment calculator as well learning about different fits on the directory.

almost going to pull the trigger on a 18 X 9's all around on 255/35/18's

obviously gonna need to pull that out to clear factory coilover perch so going to go with a 15mm spacer in the front and a 20mm in the back.

i personally like the aggressive slight poke of the aspect curve portion of the tread. seems to flex the muscles of the fender a bit but i still want the actual rim to not be obnoxiously poking. As such this keeps the rim quite close to flush.

The real question is that since i want to go with black rims on my e8h ultramarine car i'm thinking i need to go with black spacers as well?

if i went with just regular finish i would probably be able to see the spacer behind the hub of the rim coming up to the car?

thoughts?

I don't think a 20mm spacer will be what you want. That makes the rear +22. Also +27 front is very aggressive. You will need coilovers to make it work. I would stick to 245/35/18s. I'm of the mind that spacers could be painted flat black. I would consider thinner spacers. Read through the first post in the meaty tire thread. He lists all the parts you need. And some great insights.

Good luck.

thanks for the hints leonardo; i read the first few pages of that meaty tire thread once before and read it again on your recommendation everything seems to make sense but i think i can still do the spacer approach in a bit more refined manner but wouldn't mind some opinions on the following research.

have a look at this thread link at the old post pics where this guy shows his bremmer kraft wheels that have the same offset as the konig oversteer 18 x 9's BEFORE he slammed his car and added coilovers.

http://www.ft86club.com/forums/showthread.php?t=39679

he claims that with that top view pic that there is only 2 - 3 mm which i agree is too close even though it just clears. i modelled his wheel in the middle of the attached snapshot of the wheel fitment calculator with stock being on the left and it shows the same approximate 3 - 4 mm; pretty close to his real life scenario.

i found a vendor in canada here that i can get a plain finish spacer at 12mm for the front with the tire; so the adjusted offset would be 30mm. just have to paint it black so it doesn't stand out like a sore thumb with it being a black wheel. this only puts the rim at 1mm over flush and gives me the slight poke of the meat of the tire which i like as a personal preference.

measurements with this calculator show that on the inside of the wheel i have only creeped in 2mm from the stock wheel by use of the 12mm spacer.

did the same thing on the second picture showing the comparison for the rears using a 17mm spacer. 1mm under flush for the rim but close enough i think. this setup is virtually the same as the inside of the wheel well to the stock wheel; that said i have no problem dremelling off the back bumper tab.

looks to me like i can avoid the coilovers and still some room for camber adjustment.

any thoughts or concerns on the homework here?

BTW i will not be slamming or dropping this car at all.

I am sorry to say, I feel, the fancy fitment calc, is worthless. I looked at it many times.

I am not trying to bash the guy that spent alot of time making it. I applaud his ingenuity and expertise with how it functions and looks. It just does not give accurate to the mm data, like actually test fitting real wheels and tires.

Real world pics and experiences are how I chose my fitment. I dont' like poke. I live in the country with dirty roads. I just made little mud flaps!



This pic is one of the pics from the link you posted of a 18x9 +42 with 245/35/18. It is way outside the fender. A 12mm spacer will push it out 12 mm more. I don't understand how it would be 1mm past the fender.


Additionally, Do you see huge gap with my rear fitment? You think a 17mm spacer will fit? The car has no rear camber adjustment stock. You will need the parts listed in the post I talked about...

Edit: Well, if you like lots of poke, and don't want to lower your car, then the spacers you have chosen will work great. Stock height should provide enough clearance. I feel that a 3-5mm front would be better to minimize poke. and a 5-10mm rear to match said amount of poke.

[Gutterboy]

leonardo, really appreciate your thoughts on this and i think you are somewhat talking me off the ledge.

i don't want some poke to the extent of the curving part of the tire to stick out just past the fender.

I still want all four to 18" x 9" in contrast to your stagger with same tire size.

notwithstanding the fact the both your pic and the bremner pic are not exactly headon with the car to truly show how much poke because the fact that you see the profile of the rear of the car dictates that those pictures are at a slight angle therefore not getting a true picture of the amount of wheel poke from the flush of the fender.

That said you have a very significant on how far that bremner wheel is out there without a spacer and in addition to that your rear is damn close to where i would like mine to be and you have no spacer at all.

Actual tire section width is 9.7" since i am planning to go with the hankook ventus v12 evo2 k120's so i have a 1/3 of and inch or almost a full cm of tire overhang for rim protection so its not a stretched tire. Not as beefy as the 255's but will create less problems for ability to camber.

So the tires will be a little cheaper and once i have them in hand i can mount them on one side and measure up what i want for the look that i want in terms of poke and spacer to that for my desired poke and ability to camber thereafter.

Thoughts?

Camber? How are you adjusting?

I don't believe your tire will hang over the wheel to protect it. Look at the specs below... My tires are wider, and the 245/35/18 is slightly stretched on the 18x9.

9.7 section width, but only 8.4" tread width. EVO12
9.8 Section width, and 9.0" tread width. MPSS

This is natural camber added by lowering with Eibach prokit springs. You can see the slight stretch on the tire.

[Gutterboy]

i would intend to adjust camber in the front with a set of SPC camber bolts.

as for your point on slight stretch on your 245's you have a point there. I guess that's why i was originally trying to go down the road of 265's and then realized that was going to really be rolling the dice on fitment while trying to avoid coilovers and thought that i had a good chance with 255's at 10.2" section width and 8.7" tread width which would maximize traction in comparison to wheel width as best as possible considering other wheelwell constraints.

one part i never truly realize till looking at your last picture you provided is just how much the natural body of the twins tapers away from the wheel at the bottom. aside from the slight tuck in at the top of your wheel you have a damn close to flush look with your lowering and wheel size and setup.

honestly looks great.

i just think i might be ok with a tiny more poke with wheel being on flush with body as a personal preference; and the final peice of the puzzle is whether i could get the poke of th sidewall meat of a tire that isn't stretched on a square set of 18 x 9's at stock ride height and spacers given the offset of 42 with the konig 18's.

have no problem spacering, but don't want have embarrassing poke and really want to avoid the bill of new coilovers.

my priority for the traction is to put as much power to the ground with the new turbo.

thanks in advance for any insight.

[Gutterboy]

that picture of the rear wheel flushness really helps.

just wondering if you have a more straight on picture for the front to help determine how much more to flush a 9" on the front would be?

this might help ryan86 and me figure out whether things are getting too offroady look of a poke by the time you 3mm or 5mm spacer the 9 to clear the front coil perch.

just can't quite tell how much room from face of wheel to flush of fender you have with your 8 at 45 offset there and how much would disappear with the 9 at 42 offset. (hope i remember those offsets right)

[Leonardo]

This pic shows (I feel it does) the lack of poke and flushness of the 245 front tire. The MPSS has a stiff side wall that does not look too "bubbly." Not all 245/35 tires will sit squarish like this on an 8.

[pimpfighterroq]

I have a black FRS. I'm thinking about getting 18x8 +45 offset squared. Do you think I'll have rubbing issues? I'm also thinking about getting eibach pro kit at the same time. I know 18x9 would be too close.

[pimpfighterroq]

thinking about 225/40/18 with the 18x8s btw.

Welcome to the forum.

18x8 +45 all around with 225/40/18 will fit with eibach pro kit springs and look great! 225/40 is a great size. Tons of tire choices! Also, tire shops stock them. I have eibach pro kit springs installed.

The setup will look like this. (except the 18x8 konigs are concave)
Post #20 18X8 +45 wheels with 225/40/18 dropped on eibach pro kit springs.

Good Luck!

how bout 235/40/18 for this exact setup, 18x8 in the front, and 18x9 in the back, thoughts?

Yes, should be good to go. My set up fits with wider but shorter tires.

235/40 are the same weight as 245/35, half inch narrower tread, and have a .3 inch taller side wall.

Good luck!
