    Guys, I know this has been asked a MILLION times, but I have a bs question about wheels for my 77 camaro I just picked up. I have my eye on 2 sets of American Racing wheels: 1)VN215 Torq thrust and 2) VN507 Rodder. I like them both pretty equally..

    I have a pretty much stock suspension set up, would like to run 17's (maybe 18's), but am confused about the backspacing/offset these are offered in. I'd like to run at least a 245 in the rear, and a 215-225 or so up front. I have front disc brakes and rear drums, if that matters. At the very most, I might drop the car an inch or so, but nothing crazy.

    I've been searching old posts for the past few days, and can't seem to get the info I'm looking for.
    Can anyone give me a hand with this? Thanks in advance!!

    I would look at 18's and most go with 245-45-18 front 5 inch BS and 275 40 18 rear 5.25 back space , I have DSE front control arms , just an FYI and a slightly narrowed rear , those two sizes of tires end up with the same height I think it is 26.7 inches or something like that, I went through this , and was glad to finally order it and be done with it, HAA HA and the rims were 8 inch front 10 inch rear

    Its more than the tire diameter....what are the widths? That will play a part in backspacing too. For the tire size you want to run, you can go with something like a 17X8 with 4.5" BS on all 4 (No Offset). The rears could probably go 4"BS with a 8" wheel to push it out some. I ran 17X8 on the front and 17X9s on the rear. 245s on the front/275s on the back, no offset.

    The torq thrust wheels l really like and have pretty much decided on come in the following: 17x8 with 4.07 bs and -11mm offset or 4.81 bs and 8mm, 18x7 with 4.24 bs and 6mm offset, and 18x8 and 4.5 bs and 0mm offset.
    Based on the above and my original post what would you guys do?
    5x120.65 is the correct bolt pattern right?

    Can you see my above reply with sizes? With this being said, and the availability in 17" and 18" what would you recommend?

    Take a look at the tires you are wanting to use, and see if they come in the size you want , in 17 and 18 , not as many good sizes in 17 anymore , just look at the size , not to see if they sell a 17 , because they skip a bunch of sizes , and it might be the size you want, also, brakes, if you upgrade , have many more choices with 18 inch rims over 17, lots to consider

    I just looked and the torq thrust
    vn309 tt o comes in 17x7 with 4" bs and 0mm offset, and 17x8 4.5" bs and 0mm offset. I dont like it quite as much as the first style i mentioned but if you guys think it would fit better l could go with it instead

    8 inch width should fit with 4.5-5.0 inches backspace, or 0 to +12mm offset.
