New Wheels wont clear brembo's
 
Hello, I just purchased a set of wheels that I was assured would clear the brembo's on a track model. I am not the best at offsets and things of that nature but did some research and they seemed like they would fall in that range.

here are the sizes: 19x8.5 w/ 20mm offset in front
and the rears are a 19x9.5 w/ 25mm offset.

The rears fit just fine and have no problems. The fronts on the other sit right on the caliper. I know I could do spacers, and I am just fine doing that, but I mean what would have been the best offset for the front wheels? Also I did some research on the spacers and I think I am going to have to get longer studs. FML, any help on what would have been the proper front offset, or why they wont clear, also any advice on spacers, I searched through the big spacer thread but I guess I am just a ****tard when it comes to wheel schematics.

Thanks in advance.

spacers all around with built in studs...i have been running 25mm ichiba spacers for some time with no issues most likely you wont need longer then 10-15mm. easy to install took me like20 minutes...good luck

Some wheels spoke design fit differently. Most 8.5" +20 offset wheels will fit over Brembos. Is it hitting the spoke design? You could try a small 3-5mm shim spacer and not go the new studs route if you want to try that first. The 8.5" wheel will also allow you to run a big spacer, like 10mm, if you want.

yeah it is the spoke that is hitting it, I was doing some messing around and came to the conclusion that I probably needed 5-10mm spacers. The problem is, when I was fitting things behind the wheel to test what size I needed, The lug studs do not come out far enough for a lug nut to thread them so I am guessing I need the spacers with longer studs too. Was just thinking of getting the Ichiba Version II's or something of that nature.

Width and offset is no guarantee of fit. Brake manufactures do offer templates but its not helpful if you do not have the wheels.

300zx32tt91 Sep 30, 2009 08:16 AM

yeah, definitely have learned that lesson. Will the Ichiba VII 15mm spacers be a good choice for me?

GeauxLadyZ Sep 30, 2009 08:28 AM

I would try a 10mm first and see if that works. Project-Kics makes a 10mm with built-in studs, so easy, quick install.

Measure the distance from where spoke hits to where it needs to be to clear, in MM's, then buy the smallest spacers avaliable to fit that measurement.

Or, pull the wheel off hub to EXACTLY where it needs to be to clear, then measure distance between car's hub face and wheel hub face.

300zx32tt91 Sep 30, 2009 08:38 AM

thanks, I did just check on the Kics 10mm, I think that will be my best option instead of the 15mm. Like I said I was pretty sure only needed a 5-10 so im going to try the 10mm.

What size tires on the front? An 18x8.5 +5 (net after spacer) sounds a bit aggressive to me. I don't much about Kics, Ichiba, wanchang, etc., spacers, as I stick to good ole' reliable Eibach spacers for anything more than 5mm. Since this is a permanent fix for you, you could consider shim-type 10mm spacers (I have a set I don't use, actually) and get the longer studs, but I would borrow and try a pair of 5mm shim spacers to start to see if that buys you enough.

If your not getting a 25mm spacer , go with spacers that you need to replace the studs, not a spacer with built in studs.

300zx32tt91 Sep 30, 2009 10:01 AM

The front tires are 245/35/19's. My only concern is on replacing the studs is I have a nicely jacked up hand which prevents me from doing many projects on my own and nobody to help plus I imagine paying a shop to do it will not be fun. So im kinda looking for the best alternative. I dont mind paying, the cost isnt the issue as much as the time. I tried to search but I just really dont understand all the wheel stuff. The rear's are +25 I believe, am I going to need spacers on the back to counterbalance the aggressive stance on the front? I appreciate all the input guys.

300zx32tt91 Sep 30, 2009 10:58 AM

ONe other question, If I use the narrow lug nuts that fit, will I need to put in longer studs if I go with say a 5 or 10mm spacer? At the moment there doesnt appear to be much room and it wont thread but I am trying to use a stock lug nut for reference but it wont thread.

TheFarmer Sep 30, 2009 11:15 AM

Just curious what type/brand of wheels are they?

No, you changing width in millimeters with spacers. Remember your rears are still 1" wider and keep in mind Nissan's orginal 18's were not staggered at all and their 17's were only staggard by .5".

Tire width is what makes all the difference in your concern, not so much wheel width.

EDIT: Correct myself here. If you use a spacer 5mm or wider, you must replace your studs with longer ones.

Ok I test fit a 8mm spacer which was a slip on just to see if it would clear. Well the wheel clears, but there is not sufficient lug space, you can thread it but not safe to drive I would imagine. So I decided I would try the kics 10mm spacers with built in studs. So once again I put the spacer on and got the lugs threaded enough to where I could lower the car enough to see how the car is going to sit with the wheel on...That leads to problem number two. The front wheel is sticking so far out of the fender it looks like im going to a dirt track. The wheels by the way are Stern St2. (Flamesuit on) anywho, the offset on the front are supposed to be +20, I just do not understand how this can be so far off that the wheel sticks that far off. Well I guess I will go back to sleep. Le Sigh.

If 8.5 fronts, et.20 is a very good offset, and doesnt leave much room for bringing the wheel out further. I would try a 5mm slip-on spacer (dont HAVE to replace studs). If then your wheel still sticks out to far, then either get some stretched tires in the front or get new rims if you dont like the look.

300zx32tt91 Oct 2, 2009 09:52 AM

here is the problem now, the 8mm spacer just barely cleared I dont think a 5 will work. I would rather do that but it wont work. I guess ill be getting new wheels.

300zx32tt91 Oct 2, 2009 10:03 AM

one last thought. Lets say I exchange the fronts for a set of 19x8.5 with a +32 offset. I know I will probably still need spacers but with the 10mm spacer will it still stick out past the fender?

Nope...you could maybe get away with a 15mm with offsets of 32.
