well i was sitting here bored wondering what is really the max width you could run on the front of an s13, so i did this.

so i searched though a bunch of stuff an seen that McCoy was running a 275 stock body with 1.5 camber. (which you can see on page 23 post 667)

his was on a 9" rim with +35 with a 5mm spacer so its +30.

now im gonna running 40mm fenders on my new setup, then was like hmmmm 315s?

so a 315-275 is 40mm. so technaically the tire is 40mm wider just like the fender.

i would like to run a 10.5" rim so gotta figure out how to get this to not hit the coilover. so if is was still +30 the rim would stick in .75" more or 19mm.

so 30-19 is a +11 to make the inside exactly the same.

an which would move the outside of the rim 19mm out more, but you would still have 2mm of clearence. because the rim is 1.5" wider which is 38mm an half is 19mm.

so with a 10.5" rim you would be able to run a +9 to +11 an "technically" it should work, but on here an on the car is a different story.

i was planing on runnning 315-30-18 nt01s on 18x10.5s for my rear track tires. i might just bolt them up to the front an see how it all fits.

sorry for this not having pics an being a bit confusing to read, but i though someone might find this interesting.
