Wheel Offset Discussion Thread... How far can we go?

[VIP-STATUS]

Venaci is a new line of wheels we pick up from Japan TAS show,there are more wheels on the way.In about next week i will post some pictures.
For show 20's for sure.When i'm running at the track i'm planning to run 19's.
Here is the other Venaci wheels also.

[VIP-STATUS]

I'll post some pictures up this weeks when they are on the car.

I like That first Set! Can you PM me the details on options and Pricing maybe we can work something out

So lets take a look at what we have to work with and how far we can go with offsets.

I want this to be an educational thread for everyone! No flaming as we are all here trying to spread our knowledge

So stock sport wheels are:

19 x 9 +47
19 x 10 +30

at stock camber this leaves us with about 3/4 inch of room to the outside of the rim and the inside of the fender on the rears and about the same for the fronts.

We have seen that 15mm spacers on the rears put the rims close to flush with a few mm's to spare. I believe the fronts could do the same...


So the real question is at what size and offset have we gone too far?

I located this thread while trying to find help with choosing wheel spacers for the factory Sport package wheels. Am I the only one who thinks these wheels look great?! To top it off, Nissan is finally giving us 19" diameter below the Nismo package and on all 4 corners to boot. I have to admit I wish they were about an inch wider. That's what leads me to the question. Have some of my bold 370z brothers installed spacers for thier Sport Pkg wheels to fill out the fenders better? I heard mention of 20mm somewhere else and 15mm as quoted here but I expected to find a whole thread discussing all the details on this mod. We tend to be a great bunch for digging into the details.

One (maybe two) have gotten 15mm spacers on, I know they were getting 20mm for the rears soon to see how they looked. Link

So that's where I needed to look Thanks for the redirect.

I have 15mm spacers front and 20 rear on the nismo wheels, which are the exact same specs as the sport package wheels, and they are nowhere near rubbing.

guys we can go MUCH more agressive on the 370 than most of you are thinking. Run the numbers through an offset calculator and compared to the OEM sport setup you can extend the fronts ~40mm and the rears ~30mm. If you want that flush/aggressive look offsets need to be in the 10-15 range typically on 9.5"/11" setup. Anything less than 275 in the front shouldnt rub and out back your good for 305+

Same thing for me, 15's & 20's and no problems.

DannyGT (if I didn't butcher his username, sorry if I did!) is running 19x9.5/10.5 +22 all around on 275/305 tires.

My take on this is that we can run a lot more aggressive sizes than this. Then again, it depends on what you're willing to do to get to that point and what you're using your car for. A lot of wheel sizes fit, it just depends on if you're willing to do a mild tire stretch, or add a lot of negative camber. It also depends on your ride height as well. I mean, even in the Civic world (I know that world is definitely taboo on here ) the stock sizes were 17x7 +45, but my friends and I have been able to successfully run 18x9 +29 so it's all in the minor details.

I hope that made sense. I'm still waiting on my suspension setup to do some measurements to see where I can push the boundaries.

So, final question for jmlenz and Minicobra1: Can you say for sure, from your experience that there is no chance of tire to fender contact with 25mm wheel spacers on the rear and 20mm in the front? I'm now talking to Lou to place an order and just want to be sure. I don't want to put 15mm front and 20mm rear only to say afterward, "Man, I could have gone wider for an even cooler look". Put another way, Minicobra1, now that you have 20mm rear and 15mm front, do you wish you had gone up one more size? I know you also lowered your Z. I probably won't be lowering mine. I don't think that loweing these cars would provide any more cleanance; do you think it does? Did you have to modify the plastic inner fender well liner to clear the tires during full-up-travel or trim the 'sandwiched' seam on the rear inner fenders? Thank you guys for sharing all your experience. - With insight gained from some of the threads in the audio forum, I'm installing a complete DVD/Nav/Blu-tooth/backup-camera, speakers, sub and amp next week. You guys are now helping me make the best choice for this next mod. FoesFlyDennis

I should have been asking Mike those same questions.
... thanking you for chiming in too.

Time out. Thats not what that chart you posted up means at all. The min nominal max is just the approved range that the camber can be set at while the car is sitting on the ground. It says clearly at the bottom to measure value in the unladen position.

For the guys with the spacers, are you guys using the spacers with the built in studs? Or did you guys knock out your stock studs and replace them with extended studs? Or still using the stock studs?

I know from reading another thread that Minicobra1 used these spacers: Amplified Motorsport - AmplifiedMotorsport.com - performance audio auto accessories
They require replacing the original studs with longer ones that come with the kit. He also clarified that this is the only style that will work on the front wheels because there is no relief in the back of the wheel's mounting flange to clear the other style spacer's studs/nuts (the ones that hold the spacer to the car's hub). To me it makes more sense to stick with the same style spacers that Minicobra1 is using. You don't have to remember to check torque on a second set of lug nuts that are concealed behind your wheels. Also, they are lighter and presumably stronger (provided the new studs are very strong).

MiniC, I hope you don't mind me chiming in here. I've just been following your mods pretty closely. Dennis
