Diamond Black Finish... GORGEOUS!!! These are way beyond what I wanted to spend, but I don't care! They're sick!



These are the EXACT fitments for the Z33 as per the BBS site
RG-R TYPE 768 18×8.5 +23 5/114.3 18.5 lbs = $550
RG-R TYPE 769 18×9.5 +25 5/114.3 19.5 lbs = $590

The 19" fitments are 8.5 (+18) and 9.5 (+22) as well and are probably around $600F and $640R, but I didn't get pricing.

Very nice looking wheel. Do they clear the front Brembo calipers???

See my 'more bbs info' post below...I have actual pics of the 2 piece version on a silverstone Z!

Pics are up in my other post!

Luke@tirerack

actually the 350 fitments offset are 35 front and 42 rear

droideka

Oh really? Would you like to argue over what's actually on the BBS Japan site?

No, Luke. You're wrong.

Luke@tirerack

Actually BBS produces those fitments for the R32 GT-R Skyline and will offer them for the Z. Does that make it right ....



is this fitment wrong then is it is then I am wrong because these have the same offset

droideka

18x9.5 +42 in the rear? Yes, I think that fitment IS wrong because the clearance from the inside of the wheel to the strut housing is compromised by 31MM. A +25 is only 14MM less clearance.

Think long term and where you might go with a suspension upgrade. What would you choose?

umm.. look here: GTR R34 is 20mm all around....(except for 1 15mm setting)

and why dont they have the higher offset listings you are stating, on the Z33 page also..? probably because BBS sends the crappy fitments to the US dealers...?

haha

j/k

but seriously... i dont think you are going to change droid's mind about offsets... he's seen my setup.

Luke@tirerack

I would seriously doubt that since they do not even make the wheels hub centric in Japan and have no problems running in excess of 7 degrees negative camber to get clearance in some extreme cases .... neither of which would be acceptable here. But, we also wouldn't put up with our cars not being road leagal after 36k miles either

Luke@tirerack

I don't know where you are getting your figures or how you are doing the math but the numbers are actually 21.7 for the correct fitment and 4.7 for your fitment with the clearance to the strut itself being approx. 52mm from factory (I was told the last number haven't measured it myself) ...

think long term ok ....

scrub radius out of spec
ackerman angles wrong
excessive bearing wear
more bump steer and tracking issues
less actual handling ability at the limits

I would choose more durability and better handling

but, maybe I am wrong
and who offers a 9.5 ET42 for the rear anyhow we don't ?????

I don't think he is going to change many people minds about offsets, when there is a certain "look" and fit we are going for, especially if there are those that have done this many times on personal cars, with NO problems.

Luke@tirerack

I am not out to change anybodies mind just supplying CORRECT information .....

I guess it's form over function on this forum but, I will still continue to supply information when it becomes available

The OE 350Z offset is +30, so even a +35 changes the scrub radius. The +23 ET is only 2mm further off than the +35, compared with the stock offset.

Of course, scrub radius is not an issue in the rear...
Personally, I would run the more "aggressive" offset. I have done extensive testing with many offset & width variations on different cars, and have found bump-steer and bearing life issues to be almost non-existent on the newer cars (given the offset changes less than 10mm or so). Tapered roller bearings are very good these days!

Luke@tirerack

and our testing has shown different results. I would be interested in what your testing procedures are ....

Check out the little remark numbers guys next to the wheels on the BBS size listing. They have three numbers for the wheels 2, 3 , 7. Two reads: rear size in Japanese, Three reads: Tuner size in case you install this to standard cars it will stick out from fender???? Seven reads: Tire size caution??? Pretty strange. I was thinking they would mention on using these wheels whith brembo brakes or something along those lines.

Luke@tirerack

Apparently BBS Japan and BBS North America don't agree on fitment issues and I just recieved an e-mail from BBS ....

it reads:

The new BBS RS-GT two-piece fully forged wheel on the Infiniti G35 (a.k.a. Nissan 350Z). This package requires some special treatment for the Brembo brake option that comes on the G35 6-speed and the 350Z “Track” version. Listed below are the specifications.

Package as shown: (Brembo brake option)

Front:

BBS RS918DBPK 19x8.5 ET38 Diamond Black with Polished Lip.

H&R TRAK spacer kit (15mm) part # 3065662

Rear:

BBS RS919DBPK 19x10 ET40 Diamond Black with Polished Lip

(no spacer kit required)

So, maybe the info I was supplying was correct now that BBS has verified what I have been saying all along ,

droideka

Well, that's great that someone is trying to clear up the fitment issues, but I really don't care about the RS-GT. What about the RG-Rs? Do you still contend that the fitment prescribed on the BBS Japan site for the Z33 is incorrect?

Made for Brembo baby.
