Ok, maybe one of you guys that know more about wheel fitment can help. I want to run18x10 all around with a certain wheel which specs are 18x10 with a +22 offset and a 6.38” back spacing. I know that my 2005 350Z rim is 18x8 +30 offset but not sure about the back spacing. I know that this rim will have 17mm less inner clearance than stock and will extend an extra 33mm on the outer position. This was determined by the offset calculator. I know for a fact that after I place the rim on the front of my car I have about ½" to a little more of clearance between the rim and the a-arm. Also the stock rim is about 1 ¾” from the caliper while the new rim is about 1 ½”. Also the new rim looks like it sticks out pass the fender but that could be due to the car jacked up and I am unable to have the car rest on it because it has no tire's on it. I would like to run 255/40 tires up front and 275/40 tires in the rear to try to keep the tires in ratio to the stock. The car is at stock ride hight but i might do a slight drop. I have done as much research in to the setup as i can and I know that there are a few people that are running 10" rims all around with no problems but from their pictures the wheels look more flush and not sticking out pass the fenders. Ok so if some can make sense of all these numbers, here are my questions.

1) Will there be issues with this size on the front of my car?
2) Will these clear brembo’s if I upgrade the brakes?
3) What tire size should I use with this setup?

Thanks, Ansar

 

1. shouldn't be a problem. i'm running 18x10 +19 offset plus 5mm spacers so actually offset is 18x10 +14. i'm running 265/35 and my front wheels stick pass the fenders about 5mm and no rubbing. i'm lowered on hotchkis.

2. it really depends on the wheel design.

3. i would run 265/35 all-around.

here's a thread that might be useful:

Thanks for the input.Was the inside of your rim very close to the A-arm? The red z in that post is my Friend Alex car and he is the one that got me in to trying to fit the 18x10" all around. I have the touring model and a little worried running the same size all around i now he is but his car is a 03 and the 03 models seem to be more forgiving then the rest..lol. My Z is also twin turbo so i did not want to go any smaller on the rear then 275. He sould be coming by today so i can see if they wil clear the brembos so that will answer one question.

 

close but not close enough for me not to run 18x10 all-around.

 

problem solved...

btw- ppw u kno u inspired me to do it! LoL

we were the only ones that ever tried the setup...perfect for N/A but once i went turbo i needed the understeer a lil
