Time has come to order my rims, need some measurement help! (spacers?)
Hey guys,
Well my TII big brake kit is now installed on the car (minus the brake lines), thanks Billy (Respeed)! Now I am ready to order my front CCW rims...
So I took some baseline measurements a few minutes ago and am wondering what you guys think. As you can see in this picture, I figure a 4 1/2" backspacing looks about right (measurement taken about a half inch away from the spring for clearance).
(you can't really tell from the picture, but the measuring tape is not touching the strut housing, its about 1/2" off of it.)
So I pretty much NEED spacers IMO to make these front rims look right or else im going to have a serious front lip going on... The rims im ordering are 17x10, and the rear is going to be 17x12. Just wondering what you guys think, should I get 1" or 2" spacers in order to make the rims have less lip and then get the rims with 5 1/2" or 6 1/2" backspacing?
Its pretty difficult because I need the car to be rollable in the next month, and I just want the measurements to be good so I don't have any rubbing problems...
Lets hear some suggestions! Thanks a million!

You could always just order the shallower wheels,then mount them to determine what size spacers you need.No point in ordering any spacers until you put the wheels on and confirmed visually how much space you have.......you can always push OUT,but you cant go back IN,once the wheels are purchased.
Remember to leave plenty of clearance in the back for the 1st gen's solid axle to rock.Get too close to the inner wall of the rear fender,and the top edge of your wheels/tires will rub hard when going diagonal up a driveway,curb or speedbump.
For my widebody setup,I used some H&R spacers in the rear.They are very high quality,German made,hubcentric spacers which fit nice and snug.Ordered them from a local race shop,not a bad price considering the quality.
I also used extended, 60MM ARP wheel studs to ensure good torque retention and strength.They are listed for late model,metric Camaros.You can get them from Summit.

Thanks for the reply, im not going to order the rear rims yet, im just getting the fronts so the car can go back on the ground for the time being. This is because I plan on going to a Ford 8.8" diff in the rear and I need to get that all done and ready to go before getting those rims.
Hmmmm ill try and find some 1" spacers up front, by any chance do you remember what backspacing your front rims are?
Thanks!

Up front.....17"X8" with 30MM of backspace and 225/35-17 Falken FK451's.
But Im running the Selectmaz brake kit and some high quality adpators, since back in 02' they werent making their kit in anything but 110MM pattern.One of these days Ill update it to 5 lug or an FC big brake kit or somn'.
Its not the best in the world,but 4 years ago it was the only kit availible and it still works great......

Dan_s_young, 5" backspace including tire bulge is what we came up with. So, your 4.5" number sounds correct.
10" wide with 4.5" backspace and 1" or so for the wheel center thickness would be 4.5" lip - Or 5.5" protruding out from the hub.
Do you have enough fender for that? Did you measure out to the fender lip when you took the above mentioned measurements?

Do I have enough fender? I thought you'd never ask!
I feel I have plenty of fender, the trouble is filling the things up... Measuring from my racing beat spring to the inner lip of the fender is about 12 inches, so I figure the 10" wide rims can fit up there. Thanks Billy for confirming the backspacing to be 4.5"!
And luiml73 I really appreciate your input, just because of that picture you just posted I may go with the lip up front. BTW, 240z's are my second favourite car of all time!

Well I hate to say it, but im second guessing myself. I was looking tonight with my 275/40/17 in the wheel well and honestly I think im going to go with a 4" backspacing. This is due to the fact that the tire will pertrude a bunch from the rim. I figured going with the extra space between the wheel and spring is extra insurance.
4" back spacing means even bigger lip, but in the rear im going to go for some massive lip to match up with it (7-8"). So I dunno its going to be interesting to see how this turns out. Im going to call CCW tomorrow and put my order in!

Looking good though, and i like the new sig

I'll probally go with a camber plate from respeed in the future, but at the moment im focusing on drivetrain components, and the wheels.

because I have 17x12 with 4-1/2 backspacing and they rub. Less backspacing will make the wheel stick out more towards the fender and it will rub even more.

Hmmm, thats what I was doing later on and thats why I decided I should go to a 4" backspacing, but it can be a little difficult to guess how much the tire is going to bulge off the rim. I dunno I think with 4" backspacing it will do the trick...
