I know for a fact that my 96 BBS wheels have a 45mm offset.

 

Yeah, we need to add those AND the Q45 rims that I am looking at purchasing. I think that the I30 reference # on there is for non-"t" rims.

And isn't the base I30 96-99 rim 15" x 6" and not 6.5"?

Edit: Done

 

yhea, the standard 96-99 I30 wheels are 6" and that is probably why the offset is 40mm instead of 45mm. I am adding this to the FAQ right now.

 

If my stock BBS wheels were 45mm and my current Q45t wheels are 30mm, would that explain the rubbing that I get? Would spacers fix that?

 

What width are the Q45 rims and what type of springs are you on? If you are are lowered 2" and the rims are 7.5" wide the 30mm offset could be causing the rubbing. Is it rubbing when turned or when going over bumps?

 

How much did you get for those eBay rims?

 

The Q45t wheels are 17x7.5 and I'm running on H&R springs. Generally, they ride fine UNLESS I have someone sitting in the rear and I hit a dip in the road. Even rough surfaces don't rub. Only dips.

 

I actually sold to another Org member. The problem is when everyone knows how much I bought them for.

 

It is not YOUR fault that you got a good deal...I hope that you did not up the price TOO much, but $300 would be reasonable for those rims...who cares what you paid for them- you found them, posted the link, and still bought them fair and square...you deserve whatever someone will give you for them...

 

It sounds like the 30mm offset and the 7.5" rim just cause the tires to stick out to far. your wheels are sticking out more than 25mm or an inch past stock and that is your problem. You could look into rolling your fenders a bit, but spaces will only cause them to stick out further.

I am glad you posted this though, now I know how much offset I can run w/o rubbing.


oh, what size tire are you running? is it stock diameter?

 

I'm running a 235. I was thinking that my next set would be 225 and help the rubbing a bit.

How does rolling the fenders work? Someone told me that I need an aluminum softball bat to roll it.

 

234 what? I need the whole tire size

 

I've got the 17x7.5" Q45 wheels but I was told they are 32mm offset. I run 235/45 tires and get no rubbing with a drop on Progress springs (1.7/1.5)

 

235/45/17 sized tires

 

But one of the few differences between the max and I30 is the fenders and an I30 could rub where a maxima would not.

Maybe that is why I30 offsets are 5mm more inset compared to rim size than maximas. A 4th gen maxima rims that is 6.5" has a 40mm offset and a 1st gen I30 with a 6.5" rims has a 45mm offset. Maybe there is a reason for that???

 

Try something like this. Take a 2 foot section of a 2x4, or even a level would work, and set it vertically against the tire to see it it protrudes past the fender. It does not even have to go passed the fender, it just has to be out far enough to rub the inside of the fender. I bet your rear wheels just come out a tad too far and enough weight in the back combined with a small bump causes rubbing.

 

so, what do you recommend on how to fix?

 

Don't put alot of weight in the trunk or carry passangers in the back seat and don't go over bumps.

There is not really anything you can do besides get a wheel with a higher offset or one that is 7" wide. I gues you found out for us that we can't run lowering springs with a 7.5" rim that has a 30mm offset. Sucks, but you just bought a rim with the wrong offset for our car.

You could look into rolling the rear fenders a tad.

 

How about a slightly skinnier tire? Like 225/45/17? I'm wondering if 10mm would make a difference. As for rolling, how do I do that? Take it to a shop or is there a cheaper (ghetto) way of doing it?

I don't know if the changing the tire size by only that much would do it or not. You really need to take some measurements and see how far out your wheel is. I don't know anything about rolling fenders besides what it is.

 

Ok, back to this...Mike, would a 17x8 wheel with a +35mm offset help? I'm still not grasping the concept of offsets correctly. I'm looking at the Borbet Type E wheels.

 

Looking at the offset calculator...

Assuming that my stock wheels were the BBS 15x6.5" with a +45 offset, and the wheels that I'm looking to get is 17x8 with a +35 offset, the calc says that the outside edge of the wheel will extend an extra 29mm. With my current setup, it says it will extend 28mm. Now what do I do? Does it matter that the new wheels are deep dish?

 

Well, if your not willing to put up with the rubbing then you can't go with 17x8 35mm offset. Having a lip on the wheel makes no difference. Looks like you need to stay in the 17x7.5 40mm or 17x7 35mm offset region. I had 17x7.5 40mm offset and had no rubbing.

 

*sigh* damn, back to the drawing board.

 

There is a guy on here w/ 5-spoke OZ Monte Carlo rims. THye are 17", but I do not knwo the rest of the specs. THey look a lot like the Type Es that you like. Want me to dig up the info?

 

Nah. That's ok. I saw that thread and saw a pic. Not exactly what I was looking for.

Thanks for looking out though.

 

Ok, I went to Autotrend today which is ROH's East Coast distributer. They were great. Rather than getting me to buy a set of wheels, they talked me out of it. They said that new wheels would still rub for me and they don't advise it. They said that my rear seems to have a lot more travel than most Maximas/I30s they've seen. My friend hit in on the head when he asked, "Don't you have those Motivatoinal mounts?" Of course! Those give me an extra inch or so of travel. That is what's causing my rubbing. The sales guy said to save my money, roll my fenders, and my problem should be solved. If rolling my fenders doesn't work, I'm going to take the Motivational mounts off.

 

If you pull motivational mounts, please let me know.

You COULD always try to trade the Q45t rims for a set of I30t rims (just like the ones that you sold). The difference in offset might give you the tuck that you need.
17" x 7.5" Q45t 30mm
17" x 7" I30t 45mm

The I30t are 1/2 inch more narrow (1/4 inch inset) versus the Q rims, plus 15mm less offset (about another .6 inches inset). You will be right around 3/4-1 inch in from where you are on the Q rims.

Did you ever get info on how to roll the fenders?


By the way, do you two ever feel like it is just the 3 of us having a conversation in ths forum?

 

Yeah, you, me, and Mike.

You're right, but I don't want to dish out any extra money for rims that look exactly like what I have now. Not to mention, I would have to buy new tires because I don't feel comfortable with a 235 tire on a 7" wheel.

As for rolling the fenders, the guy at the wheel shop said to use a rubber mallet and gently tap on the lip until it's flush with the back side of the fender. He said not to rush because I can crack the paint. He said it'll take at least an hour per side and a lot of patience.

I think I'm going to take it to the shop because I have some other work to do. I also want to cut the bumper so that my Y2k muffler looks right (oval muffler vs. round cutout) and I want to get the Siruius antenna painted to body color.

 

Try taking a baseball bat and holding it tight against the inside of the fender while applying solid pressure from inside and out. This is where the term "rolling" came from. You roll the bat along the inner fender to compress the inner fenderwell against the outer shell (body).
