Nope, wanted to ask here first before I made any final decisions.

What offset would work better with those sizes? Max rear tire I am looking to run is a 345. For the front looking at 275ish might be to small for 10.5s though.

Car is at the body shop now, so now is a good time to get it all figured out.

 

Yes they're 9.5" wide

 

Maybe mods need to.create new thread
"Neutral wheels and tires"

Shouldnt nothing under a 285 be posted

 

There are threads for 18", 19", and 20" wheels already created that the non-aggressive questions should be asked in.

 

10.5 up front has been done many times, I'm sure you can find examples you like and go from there. 12 inch wide rears with 345's is going to require widebody. I'm running 11 inch wide rears and my wheelwells are full with fenders rolled flat, I don't have any room to go closer to the damper or fender. Good luck. Post pics when you're done.

 

I liked my 285/30/18 on the front 18x10.5 +15 a lot.

 

I saw a few people running the 10.5's up front. So really wasn't worried about the front, more the rear. Just tying to fit the widest tire possible under the rear with a good roll and pull. If the 12" with 345 requires widebody, I'm not ready to do that quite just yet haha.

Thanks for the info Scott. What would you suggest for the rears, going off of what I said above?

 

Seibon offers a +10mm front & rear cf fender.

 

 

Depends what you end up deciding on for the rear, as it looks like you're not doing the 12" rears and widebody just yet.

 

I'm going to keep the stock body for right now. When the time comes for me to do widebody, I'll adjust fire then. For no,w I just want to fit the widest tire/rim I can with the body the way it is. If its 315 on a 11 that works too.

 

Its done!
Front: 275/35-18 on 18x10 +25, -2 degrees camber, zero toe.
Rear: 295/35-18 on 18x11 +30, -1 degree camber, 1/16 total toe in.

 

If that's the case i'd go with 11 inch wide +30 with a 315 and set camber to around -1.

 

Yowzers. . . looks awesome

 

Thanks Scott. I really appreciate all your help and advice when I was ordering my wheels. I think it turned out great and I can't wait it try some larger tire sizes in the future.

 

I think 12" rears are doable at about +30 to +33 offset. Assuming they clear the suspension inside, and I think they will based on SoCalHR07's measurement pics, they will only stick out 1-4mm farther than the popular 10.5 +15 setup. 345 would be pushing it, but 335 would probably work. I'll have a real answer for you in a few weeks once I get my new wheels in.

 

You're welcome. Glad I could help!

 

nice outcome socal... really reminds me of my setup.

 

I would not go any closer the the damper in the rear than mine are! My wheel contacted my damper at around -2.2 camber going through dips. My pictures are with no weight on the suspension and the wheel gets MUCH closer to the damper when compressed. I have about 10mm clearance at my ride height and I'm sure it comes very close as it compresses. Get spacers and pull the crap out of your fenders.
