I want an extra set of tires for AutoX so I bought these C5 rims. What types of modification do I have to do to get them to work. I know that the center hole must be filed out alittle, but I am worried about the back spacing in the rear. Do I need to use a spacer? Also so what Is the widest tire I can fit on these rims. (17x8.5 front -- 18x9.5 rear) any advice would help.

 

just take off bolts and bolt the new rims on........275 on back 245 on front

 

On the rears grind either the center of the wheel or your hub about 1mm, just do it till it fits, its not much material to remove.

I know a guy with these wheels, they run fine, no backspacing issues, 18s on rear 17s front.

 

Do you happen to know what size tires he runs (Dr. Mudge)? Also, does anyone know the average cost to powder cought a set of rims?

 

Whatever the stock sizes are, he bought the whole setup for $400. Probably 275 wide on the rear, profile 35? 40?

Fronts should be 245 or maybe 255, I'll ask when I catch him tomorow.

 

Hey MANIAC! Juan got his car running tonight. We'll have to see if he kills himself at the autox this sunday

 

I have a 98 z28 w the c5s and the rear tires seem to rub. would spacers help me at all? if so what would anybody recommend???

 

All you need to do is beat out the front inner fender well with a (big) hammer. spacers will work too, but they cost money and if you want to be safe with spacers you will also need longer studs.

 

I have a set of 97 C5 Wheels...I had to grind a slight bit of material of the center of the rim. I am running 274-35-18 on the rear and 245-45-17 on the fronts with no rubbing or any issues.

 

you most likely wouldn't have to worry about any rubbing with 275's but I am running 295-35-18's in the back so they are a bit wider. 275-45-17's in front.
