Hey everyone, sorry for another thread on this subject, but I've been doing a lot of reading, including the sticky, and it's a lot to take in. I'd appreciate some help in figuring out the specs I'm looking for. Some background, my car is an 06 coupe 6MT, stock everything. I might start looking at a small (around/about 1") drop in the future, but not for a while probably. The car is my DD, with spirited weekend driving through the mountains.

So far, I know I want a setup that will give me neutral handing. I'm assuming a staggered setup won't do this for me? I'd also like a flush look with the wheels and fenders. From the reading that I've done, I know the factory sizes and offset, and I know that I don't want to go lower than a 20mm offset, out of concern for my wheel bearings. What I could use some help in is, what diameter would be more ideal? In your guys' opinions, is 18" or 19" better all-around for straight-line handling, cornering and road comfort? Would an 18" wheel with wider than stock tires be the best compromise? What range of offsets would give me the flush look, and what offset would be best for handing?

I'll keep googling and reading, but everything's so scattered throughout the internet that I'm struggling a bit. Thanks in advance for your guys' help!

 

A staggard setup is better since the front of the car is heavier and the rear end has a tendency to kick out on sharp turns. I'm assuming your OEM wheels are 19", which have an offset of 31(front)/33(rear)mm. Measure how far you want to bring the wheels out and use the offset calculator on this forum to get an idea of which offset you need. Performance wise, 18's are better since they usually weigh less. Wider / stickier tires will help the car corner better, not offset.

 

Will the OEM stagger of 0.5" be enough to keep everything neutral? Also, should I go wider on the wheels and tires? From what I understand, the increased grip wouldn't really do too much for me since I'm still running stock power and everything, right?

 

One of my favorite things to do with SLICK are mountain twisties at excessive speed. Wheels are 19X9 (f) & 19X10.5 (r) with mid 20 offsets. They could sit a little flusher but I don't believe in spacers. My tires are 245/35 & 275/35 Michelin Pilot Super Sports because I wouldn't run anything else! The suspension is set up with Stillen sways and Power Grid end links, Tein Z H-Tech springs, Tokico D Spec shocks and a complete SPL camber kit. Hope this helps if you're looking for the ability to have major fun in the twisties...Gary

 

I wouldn't say nuetral since the car is not perfectly balanced from the factory and there is always room for improvement. The small stagger of the wheels will not affect the handling enough to notice, its the tires that make the difference. Going a little wider with the tires will benefit you whether you're stock or not, just don't go overboard. For example, the stock front tires are 225, most will go up to 245 on OEM wheels which is a small increase but will still help slightly.

 

Yeah, I read that one thread on nicoclub with the factory and popular wheel specs, yours look pretty similar, I might just go with that. How much of a drop did you get with your springs? I have a pretty steep driveway right now and I'm afraid of any drop because of it.

Sounds good, looks like I'll end up with 245 front, 275 rear since that seems to be the most popular.

Also, one more question to anyone, does hub size (bore?) make a big difference? I know the stock one is 66.1mm, I'm assuming most aftermarket wheels won't perfectly match the hubs and will require an adapter of some sort?

 

I have a steep driveway too which is why I enter and leave at a 45 degree angle but the main reason is my KurumaZ bumper. The 350Z H-Techs lower my coupe about an inch in front and slightly less than that out back closing up the gap over the top of my tires...Gary

 

I'm in an 03 sedan, stock suspension, 17" stock rims running 215/45/17. I'm eventually planning on dropping the car a bit, but for right now I would like to go larger with my wheels/tires I'm thinking 19" Rays. Most of the posts that I see are one aftermarket suspensions. What size tire will fill out the best with 1 finger between the fender and wheel? Does lowering the car 1" or so make a difference on the size of tires I can run to keep the same look? How wide can I go without needing to do any modifications?

 

The '06 G35 coupe wheels (19" Rays) work/look great on the first gen sedans! You can run 245/45s on all four corners without issues and enjoy better handling too. Lowering your sedan, unless you have deep pockets enjoy the stock ride height. Search using the word Lowering you'll see what I mean...Gary

 

Hey Gary, I know you said you didn't believe in spacers above, does this apply to hub-centric spacers too? Also, I know the OEM tire sidewall is 40, does your lower sidewall of 35 affect the speedo, or is there an adjustment that you did? Lastly, did you have to roll your fenders to accommodate your drop and wider wheels/tires?

 

Yea I see what you mean, I think I'll be happy once I fill out the wheel wells
