ok so i called discount tire direct and spoke to a very smart guy about ordering my new wheels. i told my stock wheels were 18x8.5" with 50mm offset, 5x114.3 bolt pattern and i was interested in ordering the 18x8.5 with a 45 offset 5x114.3 tsw nurburgring's. my only concern was if the wheel would clear everything like the breaks and what not. he looked it up and said he had to call tsw's rep and not even they were sure he said the tsw guy was worried it woulden't. So he suggested i could run a 18x8.5 with a 20 offset 5x114.3. he said this would deff clear but my rims and tires would stick out 1 inch into the wheel well from where the are now.


dose anyone have an offset like that im worried about the wheel sticking out past the wheel well and looking like ****...any ideas comments would be great

ps. im running the stock tires that came with my 18 bullets

 

A 20mm offset is a bad thing for the S197. A -45mm is what Saleen, Roush, Steeda and Shelby have. It puts the tires deeper in the wells.

I have Steeda Pentars w/275's and they clear the wells just fine. As for big brake clearance? You'll need to talk to TSW, go w/a brand that promises clearance, or take your chances. Read this thread https://themustangsource.com/f691/ca...-wheel-485055/ and really look at the pictures of the 36mm offset w/295's and it will give a basic idea of what's happening.

 

I agree with Walt and I am also running Steeda Pentars. 45 mm offset is what the S197 platform needs. And the difference between 20 and 45 mm offset is 1 inch like the guy told you.

 

yea when i heard him say 20 offset in my head i was like WTF that sounds wrong .... i dont plan on doing big breaks im sticking with the stock ones..i just called a local tsw distribtor and he is telling me the guy i spoke to is not as bright as i thought and that the 18x.8.5 tsw wheels with the 45 offset will deff clear all the stock stuff not to worry

 

Thanks Scott...

CoffeeGTCS;

You really need to do your homework and get what fits. If you get a poor wheel fitment, you're asking for trouble. Not only will it be a waste of money, but you could possibly cause wheelwell damage when you hit a hard bump and those tires hit the lip, not to mention tire damage...

 

whalt the problem is every place i call i cant get a strait answer if it fits or not one guy says absoultly and another guys like ehhh idk its driving me crazy ... i dont understand if i give them my rim and tire measurement now and the new rim measurement i want to go with and the only number thats diff is the offset is going from 50 to 45 why they cant tell me if it fits or not ... isnt that there job ?

 

It should fit, but no one can say for sure until you try it (unless they have tried it themselves). There is always a slight chance that because the way the wheel is made there may be some fitment issue. If you can, have them get the wheels in, then test fit them on your car before any final purchase agreement is made.

20mm is definitely not desirable. I've had the 17x9 22mm offset wheels I used to use for autocrossing on my SN95 mounted on my '08 Mustang, and with the 265 wide tires I have mounted, they do stick out past the fenders a little bit.

 

yea its amazing im ready to pull my hair out and my dad just shakes his head and laughs haha how dose a company that only sells rims not know if there rim fits a car ???? that just boggels my mind the only thing they sell is wheels haha. i found this on tsw's fitment page

http://www.tswalloywheels.com/app_gu...Mustang+-+Rear

they mention the 18x9.5s fitting but not the 18x8.5s allthough when i call up they say the 8.5's will fit my worst nightmare is purchasing these rims and then having them not fit its really starting to drive me crazy im ready to give up on modding my car all thogether cause everytime i try and get something it turns into a phone call / email company nightmare unless its a made by ford part

dunno if itl help but on the 2nd to last page of that thread, page 66, ChrisMustangGT has the same wheels your looking at. could pm him and see what he has to say about them. i actually just saw the pictures of his car with those wheels on and i IMMEDIATELY fell in love with them. i think they would look SICK on my S1NISTR

let us know how it all works out since i might be getting these same wheels in the future

 

will deff keep you guys posted i know the 19x9.5's will work but i rele dont want to buy new tires and rims i want to stay with my 18x8.5 tires and imo the 9.5's are way to flush with the wheel well

 

Offset is just one part of the equation...Different wheels have different ''back spacing''... Most wheel manufacturer try to design their wheels to fit a wide veriety of car makes and models. That is the reason they don't know if that wheel will fit your mustang.

So you need to consider "offset and back spacing" when shopping for wheels.

 

Wheel Backspacing and Offset
Before mounting a set of aftermarket wheels, there are some dynamics involved with fitment that are best to understand first.

4. Offset. The distance from the centerline of the wheel to the face of the mounting surface of the wheel that contacts the hub.

 

What Walt said...lol
