I know a couple of people on the forum that are running 10.5's on the back I my car I was wanting to go with 19's and wondering what is all involved in doing that setup.

 

The key is to choose the correct offset as well as tire size

don't quote me on this but you'll probably need something like a +45ish offset as well as stretch a 275 tire to make it work.

 

I have 18 x 10.5 +43 on all four corners lowered with no fender mods

+45 is about as far inboard as you can go with 10.5" in the rear to clear the fender lip. Anything lower will require flattening or removing the rear fender's lip flange. Anything past +35 will require rolling/flairing the fender to have proper clearance.

 

^^what tires are you running?

 

TeamRX8 how low is your car

 

I believe that TeamRX8 is running a 265/35/18 Advan Neova which is actually a bit wider than a standard 275/35/18
