Im looking at doing concave wheels the rear wheels are always more concave than the fronts is it possible to put the rear concave wheel on the fronts to give the all around look
example- Vertini Magic the 20x10.5 in the rear is very concave but the 20x9 for the fronts is not
Can i put the 20x10 up front from the back and have the 20x10.5 in the rear

 

What offset are the rims?

 

well i havent bought the wheels yet but before i order i would like if i could . they come in 15,20,25,30
Vertini magic

 

I run 9.5 width up front (10.5 out back) You just want to ensure a staggered setup so the VDC treats you right. Some of the more highly versed folks will chime in with the percentages etc that you need to keep the computers happy

 

you may run into problems with it rubbing on the thrust rod in behind the wheel when u go that wide. especially since the extra half inch would have to go on the inside unless you want it sticking out the side. a +25 offset with a 10" width would be real close to flush and would be ur best chance of not rubbing.

 

So question how is it that some of these guys have really aggressive fitments with no problems?
Is it more so the offset? Or the actual Rim?
the reason why i say is cause i say a guy on one of the other forums with xxr 20x10.5 all around and with 23mm spacers and he rolled his finders to have no rub

but i get what your saying about the thrust rod
I just want that concave look up front just like the back

 

^No more then 3% difference between the front and rear tires: http://www.miata.net/garage/tirecalc.html

 

What?

 

If I'm not mistaken, iseechris is running 11" wheels in the front.

edit: Yup, chris' specs:
19x11 +10 4.5 in
19x11.5 -2 5 in

 

Yeap. 11s up front FTW.

Though I sold them and back to running 10s in front lolz

 

when you go too wide with the front you may rub the rim on the thrust rod thats behind the wheel when you turn the wheel sharp. i ran into this problem with my 9.5s but i also have a sharper turning radius.

as for the concave look i know what you mean i wish the lip on my rims was bigger up front. the concave is more on the rear because of the distance from the outside lip of the rim to the face where the hub mounts. for the rear wheels the hub is in more than the fronts. even if you get a wider wheel the extra width has to be added on the inside portion of the rim. to get what your after you can run the 9.5 or 10 or 11 or whatever will fit but the offset is what will affect the concave. whatever width you choose just make the offset very aggressive and maybe a bit of tire stretch, the fronts i think come semi rolled but if u can do it more it cant hurt. itll never be as good as the rear but thats how to get it as close as possible. theres a rim offset section with pics start looking around and what offsets r the most flush and you like.

 

sorry i meant compression rod i got confused with X5, same part different name

 

I don't know what you're talking about...I have 10s in the front and I don't hit anything...

 

sooo what your saying is that you dont understand anything except your own rims? thats why i said you MAY run into problems as in its possible but i dont know for sure. like i also said if you took the time to read i have 9.5's that rub proving the point that everyones cars different depending on offsets and width and ride height turning radius.
