FIKSE FM/5

EDIT:i have been callin fikse and e-mailing the and they got a quote comein for the wheels i want.. so i'll let you guys know...

 

should i do more dish in the back???

 

I don't think i've ever seen fronts "tubbed" Whenever you look at autocross audis and other cars like that it just looks like they put huge fender flares on the car to be able to stuff huge tires underneath and still be able to turn lock to lock without rubbing.
Here's what i'm talking about. The audi's on the left are autocross audi's the top one from the GT class of the speed world Challenge and the bottom one is from the German touring championship (DTM). The cars on the right are the factory original a4 and s4 (top and bottom respectively)

Hope this helps for what its worth

 

The problem with 'tubbing' the front, is it isn't the inner fender that you need to clearance. the struts and tie rods cause clearance issues before any sheet metal does.

FWIW, there are a couple of people who stuff 18x11 under the fronts of our cars.

 

maby you would be better off with the "wide Body" kit.

 

i think tubbing the rear and getting the widebody kit is the way to go . People get 17x9.5 in the front all the time , with 5.5 bs . If you go the wide body kit you could probably go to an 11 inch wide and then have to clearance some room out to get it to go lock to lock . But for 13s on the back , kandiedz had 18x10 on his car and they looked stock so with some work and a widebody kit it could look right .

 

that's some crazy backspacing.....

you would need to work the fenders more then anything and use a wide body kit. something like this.

 

or this..the front strut assembly would have to be changed otherwise. the rears on the otherhand could easily be done with some tank work and minitubbing but you couldn't do the fronts wider then 11" without the above.

one things for certain you had better only be racing the car as driving it on the street with anything other then perfect pavement would be terrible. not to mention the amount of power you would have to run to have it out accelerate a car with less and narrow wheels.

would look cool if done right though.
