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

[jmlenz]

Based on the feedback of many other members here with aftermarket wheel/suspension and/or spacer setups I would say you should have no issues with your intended setup. Since you say you are not lowering that def makes it easier to run a wider spacer too. Some aftermarket wheel 370z-specific fitments push the wheels out over 30mm from stock so yes running a 20/25mm spacers should be no prob.

and for the question regarding the spacers...I would always recommend going with spacer type that replaces the factory wheels studs and does NOT use the built in stud types.

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

Thanks JMLNZ,
I'll post photos after I do it.
I also noticed that Lou doesn't list 25mm spacers on his site, only 20mm or less.
I'll look around a bit.
It may be a few weeks though.
New audio/video system is happening this week.

I don't really understand what these offsets do. My basic understanding is the higher the +##, the farther the rim sticks out from the hub? I see these stock offset numbers, and these other numbers, and really am not able to put it together all too well. I dislike rolled fenders, I despise negative camber and I don't care much for rubber band looking tires or stretching them to the point where a 45 tire looks like a 25.

So, If i were interested in Forgestar F14's, what sizes should I look at since they have a certain range of max/min offsets available, assuming a slight drop on coil overs and camber adjustments/parts to zero them out? Ideally I would like 275 front and 305 rear. Is this a pipe dream? I little help would be appreciated. As a side question, how deep would the concave be? DDM's don't look too deep, but it could be the angles.

Thanks in advance.

I am going to see what I can do to help you and to help explain the concept of offsets to you...

The lower the offset the closer the face of the wheel is to the center of the car. The higher the offset the further the face of the wheel is from the car. Camber is your friend and I stress camber is your friend and should be used in moderation just like anything. Camber will increase your tire's contact patch in a turn thus giving you more turn in response and grip. All of the offsets I just posted a few posts ago will work with -2.5f and -2R camber the front is fairly aggressive but the rear is tame when it comes to camber. I would not buy forgestar! Members like caravan and others have had major issues with quality and delivery times. Being quoted 4 weeks delivery and then not receiving them in 20 weeks makes you reconsider your purchase! They have major issues with colors being consistent! If you want to know what sizes fit try to stay as close to offset as the past couple posts.
