Really depends on the offset. You should be okay for straight line though.

coby-ss

so with 18x8 .... what offset am i looking for now with those spacers? (1,25inch)

slowswap

18x8 +72 would give about the same offset as Enkei EKM3's that you see on Cobalt's.

18x8 +67 would give about the same offset as MSR 045's that you see on Cobalt's.

coby-ss

and if i get those 19mm adapters frpom motosports than?

can someome explain me what is an offset seriously?

slowswap

With +19 you'd be looking at.....

18x8 +59 for Enkei EKM3 look.

18x8 +54 for MSR 045 look.

this **** is confusing lol. i dont get it. so ill just ask.
I have wheels that are a 40mm offset and if i get these adapters that will make them a 59mm offset if i get the 19mm adapters?

and 59mm will be ok?

slowswap

If you have +40 offset you'll be at +21. That'll stick the wheel out 1.33" more then stock. That would be past flush.

You take the adapter and minus it from the offset to get the true offset you'll have.

ok now i got ya. thanks for all your knowledge. i dont know if i want to run my other wheels and tires tho bc they are 17x7s 225/50/17.

coby-ss

i dont get what the offset mean.... lol
is it the distance between the end of the wheels and the wing of the car?

if i buy wheels with offset of 38mm...with the adapters they will be at 38+19 = 57....is it ok? or the wheels will pop out of the wings alot?

slowswap

38-19=19. You'd have a +19 offset. You need the rim to have a high 50's offset so you can subtract the spacer.

ls1fbody

no, its the measured distance from the centerline of the wheel to the mounting point.



The spacers move the wheel outward, so you need to add more + offset to push the wheel back into the wheel well.

coby-ss

so i need to find a wheel that have 55+ offset?
wow i didnt even saw that before

what about TI - ti5 18x8.5 +50

slowswap

You're better off just getting something for 5x110 and quit wasting your time.

coby-ss

yeah thats what im thinking now....but they are no mag in the 5x110 that i really like and i really wanna change my stocks one

I got 20mm adapters from motorsports tech, hub centric to the hub and wheel centric to the new wheels. I ran rota grids 18x8.5 @ 44mm offset I believe. Perfect for the front, very aggressive but definitely the widest id go on plastic fenders, the adapters ride like stock and I tracked them multiple times, I broke axles but never those and you'd be hard pressed to break a set yourself.

MAJOR THING IS.....your gonna have to shave down your stock wheel studs a few mm. If you have a wheel with deep enough pockets in between the bolt holes you'll be fine but mine weren't deep enough. I was hard headed and try to fit them on anyway out of excitement with an impact and let's just say I spent the better half on 12 hours peeling wheel studs off of studs. Not fun.....studs on the adapter were perfectly fine.

20mm is the smallest they will make you for an adapter, bigger of course would leave you less room on wheels to play with. I love the adapters and I did have them for sale in a thread I made recently but I love the ability to throw on 5x114s. I run new adapters for the corvette wheels now 33 up front with a 20 out bacl, we have plenty of room to play with out back. You shouldn't be as worried because a cobalt has metal fenders, hell a fender pull could yield you an extra 10-15mm of room to play with, wish I had that luxury at the moment as you can get really aggressive with your wheel setups.

All in all....adapters are fun and cool but getting CCW to make you custom wheels for your car is the way to go....any width, offset, bolt pattern, $500 a wheel is a damn good price. Already got the specs I want so ill be getting those hear shortly. Such a wheel-***** lately, 6 sets of wheels laying around and still not satisfied haha.

Menace Kustoms

So, if I found some +42s and added the adapters, these will fit right? I know it will be aggressive (sounds good to me), and I will probably need a roll, maybe a slight pull.

I bet you will see some poke with that, you will have to do some pretty extensive fender work.

Menace Kustoms

Well, going by what dom1013 said, they should be pretty close. Some poke doesn't scare me. I don't drive the car fast, it's a 2.2L auto for god's sake, lol. I would have 1mm more poke than he did because I would get the 19mm as opposed to the 20mm he had and the wheels are 42mm instead of 44mm.


dom1013, do you have any pictures of the Rota Grids? I am really interested on seeing if I could pull this off. I found a really killer deal on some wheels that would be different from the norm!

Stevo

so do these work well or...? I just bout a G35 and I have my old rims from my SS. They are 5x110 and the G's bolt pattern is 5x114.

dom1013

You got the holy grail of bolt patterns....dont worry yourself w/those 5x110s I have a mint set of 22" Asanti's that would look great on it BUUUT yes, these adapters do work well.
What's the width of these new wheels your trying to get w/the 42mm offset. If you can get a 19mm adapter that'd be okay, you may have to trim a little more off of your factory wheels studs though. I know motorsport-tech won't do less than 20mm for adapters, who was making the adapters for ya?

I do have a couple pics of the old set-up.

18x8.5 44mm offset plus 20mm adapter equals a final offset = 24mm which extends 37mm over the stockers(which are 7" wide @ 42mm offset).

If you run a wheel that extends that far out, your going to most likely have to stretch a tire. I used 215/40/18s so it would flow well up front which was pretty much dead on the limit w/o adding much camber. The rear had room to go....the pics don't really do the set-up justice but you can get an idea of what you guys can run.

Also, you guys are still in uncharted waters as we are yet to know what a decent fender rolling/pull will yield.


Here's some pics......



Notice the poke up front...



The rear....



215/40/18s on a 18x8.5.....I would've definitely ran a 45 series if I could do it over again




On progress springs with so much wheel gap

Menace Kustoms

Well, Motorsports Tech listed a 19mm on their website. They are 8.5, just like you had with those Rotas. Yours really doesn't poke that much, and I think a little pull would do wonders. With H&Rs, I should be a little lower than those Progress springs, so I think it could look pretty decent.

dom1013

Oh ok, sounds good....yea, those H&Rs would definitely sit lower and the poke wasnt much, just enough to get aggressive just past the fender. You might be okay with just a roll actually.

Grab your wheels and see what happens, if you need a pull just pull around your wheels ya know. Definitely keep me posted, a flush balt should look great. What wheels did you go with BTW?

Menace Kustoms

Well, I haven't gotten them yet, but I was looking at a set of TSW Donningtons. They're different and they fit the look I'm going for.

Stevo

haha well I just wanted to keep my rims instead of buying new ones at the same price but oh well, I think I may get new ones anyway. 22's wow damn, wayyy ro big for my taste! haha thanks though

Bumpin Balt

$200 for adapters? There ARE nice wheels out there in 5x110, you just have to hunt for them.

1) Those wheels look sick in general!
2) That gap between the tire and wheel looks horrible!
3) They stick out too far. Bad offset.
4) Any lower and you will have rubbing issues with that offset.
