I need a little help on deciding the front size and offset for a 99 trans Am. I am already set on 18x11 rears with a 43 offset. I want the front to be as flush to the fender as possible. Car is lowered about 1.5 - 2 inches in the front. I also plan on rolling the fenders too. Not too concerned with the width of the three options I have as I would rather have the wheel flush more than anything. Currently running 18x9.5 C5 Z06 (54 offset?) wheels on the front and I hate how sucked in the fender they look. My options are :

18x9.5 29 offset
18x9.5 50 offset
18x10 30 offset
18x10.5 54 offset

 

this is what 18x10.5 +50mm offset looks like in the front

 

Those look perfect. Did you have to roll the fenders or any other mods for clearance? Are those the S71 or Ventura?

 

nothing in the front, they did rub on the fender liner at full lock but I let it self-clearance. they are s71's

 

Thanks for the info. The Ventura's only have 54 offset in the 18x10.5. That will push them 4mm more into the fenders than yours correct? Not too worried about fender rub in full lock but wondering if it will hit or rub any other suspension components?

 

yes, it will be 4mm set inward than my setup, could put a small spacer to make up the difference if you wanted but 4mm is really small (.157 inch). I have ARP extended studs which would allow for slip on spacers if I needed. no rubbing on suspension components, if anything your tires would be the issue there, I have 295/35 NT05's and no rubbing issues.

 

nice choice on the wheels, man.

 

Really not trying to have to add a spacer to the 54 offset since I don't want to have to change the studs.Worried about the wheel hitting on the spindle. If I went with the 9.5 in the 29 offset would that be too much or flush with the fender?

 

29mm offset would stick out 1.22" (31mm) farther than where my wheels currently sit, so that wouldn't work and would put them out past the fender.

 

The difference between your wheels (50 offset) and the ones I am talking about (29 offset) would be 21mm. They are narrower at 9.5 inches also. According to the wheel offset calculator the 9.5 would extend an extra 8mm (0.31 inches) more than your wheel, the push out to the fender not as great due to the 1 inch width difference. Cant really tell by your pictures if 8mm more at the fender would stick out passed the fender or not. I also have a TA so I dont know if the fenders extend a little more than your Camaro, thats what I have heard at least.

 

Unfortunately they don't offer the Ventura's in as many offsets as the S71's. Wish I could budget the S71's but I can't so I am stuck with the Ventura's. To throw another one out there, they do offer the Ventura Drags in an 18x10 (45 offset), I think these would be perfect fit but they only offer in 5x120 bolt pattern and also not sure if the styling of the Drags vs the normal Ventura's are exactly the same style, per the online pictures they do look pretty darn identical. Might have to give them a call to see what they say cause if they are identical styles I think i could get the 5x120's to fit?

 

that thing is still alive?

 

ha, my math didn't math there, yes 21mm not 31mm difference. that may bring you closer to it fitting but I measured on my car and anything over 1/8" outward would hit the fender for sure. T/A's do have wider fenders from what I have heard but haven't owned one myself to know for sure. 5x120 does fit on these cars as it is within factory tolerance for the 5x120.65. I've seen people on this forum run 5x120 wheels for years without issues and other have issues right away so seems like a crap shoot, there are plenty of threads on 5x120 wheels on here to do some researching

I mean I still have the car, it hasn't run in 5 years now which is depressing to say that. I am in the middle of doing a turbo build but it kind of spiraled into doing a bunch of "while I am here" things and then bought a new house and got married and I haven't touched it in a while lol hoping to have more time this winter now that it is sitting in a nice 3 car insulated garage that came with the new house
