Heh. Maybe you should break out the steel wheels, or better yet, how about four GT-R space savers. That would be an interesting look on the track :) In fact its almost worth trying to borrow a couple of space savers just for a photo op.

Apparently my SSR Integral wheels weigh 8kg for the front 17x8" and 8.2kg for the 17x9" on the rear.

There is a website something like www.wheelspecs.com or something that has weights and other specs for heaps of different wheels.

Ok I don't know the weights with tyres but this site has the wheel you are looking at.

http://www.wheelweights.net/

This wheel is about 9kg (ish) - could only find the weight of the 18x7.5 which is 22.3lbs... so I just reduced it a bit. This is a great looking wheel!!! And a great price!!!

The 15" S14 wheel is about 7.9kg... but obviosuly there is alot more rubber attached when you put tyres on.

If you take a look at the more expensive Jap stuff, eg. Gram Lights 57S in the same size (17x7.5) it is 7kg (ish). Also a cast wheel (unless you go for the PRO version) and costs about $500 or so each wheel. So you basically pay for the weight reduction. Maybe they are stronger but I don't think you sound like the person that is taking his skyline to the track...

Hope this helps

Cheers

Hehe, that was the whole point of the exercise of trying to find lighter rims... as i am starting to do some sprint days, and want some lighter rims for the benefits they give to a track car...

if i was purely after looks, the weight wouldn't bother me

Don't know whether this helps, but I just weighed a standard R32 gts-t rim + tyre I have here and its 18kg.

Wow, I'm a little surprised as I thought of that wheel as looking quite light. So are those wheel cast then? A wheel weight website somewhere said the 32 GT-R wheel is 16lb/7.2kg, but that's just the wheel. Anyone weighed the 32 GT-R wheel with a tyre mounted? (Obviously varies with tyre, but for a rough idea?)

I had some 17" ROH Adrenalines that weighed 19kg with a tyre, and I thought that was pretty porky, but maybe not that unusual? Current ones are 15kg with tyre, and I was casting about for something potentially lighter, hence wondering about 32 GT-R wheel/tyre weight.

what u have to understand is that a wheel may be small in diameter, and thus weighing less than say a 18" wheel, but the tyre to keep the same overall diametre of the wheel and tyre u need to run a higher profile on the smaller diametre wheel, this means the tyre weighs more.

the GTS-t wheel is cast yes, the GTR wheel is forged, weight wise there is not a whole lot of difference, the GTR wheels weighs a bit less, but remember the GTR wheel is 8" wide and the GTS-t is only 6.5" so its not really a fair comparison.

remember, weight is relative to the size and strength of the wheel, no point having a really light wheel if its weak as piss and too thin to fit a decent size tyre on it. 19kg isnt overly heavy, but id imagine the wheel was something like a 17x7ish? to give u an idea, R33 GTR wheels (forged)weigh around that, are very strong and rigid, are 9" wide, with near new 235/45 tyres on them. they weigh around 9kg on there own without tyres.

ROH's arent a particularly expensive wheel and use a pretty standard casting technique.

My 18x8.5 TE37's weigh in at 8kg...very light for an 18" rim in my opinion...I think the LMGT4 is 1 of few that is lighter than TE37's inch for inch...

I expect the 18x9.5 rears I'm getting to be 8.5-9kg, but I'll have to wait until they're here to weigh them

So 32 GT-R wheel with tyre would be around 18kg or so anyway? Anyone weighed one?

(The ROH was an example of a fairly nasty wheel, that's why I was surprised the GTS-t wheel was nearly the same weight, as the ROH looks like it has lots of excess material, but the GTS-t wheel looks pretty clean.)

the casting technique is ultimately what determines the weight, the design does play a role, but not usually as large as the manufacturing technique.

the weight of a tyre and rim will vary by a few KG's depending on tyre size, tyre design, tread left etc etc so u really cant compare. plus the GTR wheel will usually run a wider tyre as well so theres extra weight.

There can be more variation in the weight of the same sized tyres of different construction than the weight of a one forged rim verssus another forged rim. A new tyre with 8 mm of tread weighs more than used tyre with 5 mm of tread, let alone a worn out tyre with 1 mm of tread. Take a look at what is written on the sidewall of a tyre, research how many steel and/or kevlar belts, shoulder and sidewall construction, plycord, bead filler and wires and the chafer. Saving 1 kg by spending $800 more on a wheel and then using a tyre that weighs 2 kgs more is not very cost effective and may do nothing for performance at the same time.

      S15 Spec R

      By RP1421 · Posted

      Update time!  The JZX110 had some maintenance needing to be done, so a lot of the seals with replaced to fix some oil leaks. Also used this opportunity to whack on a front mount that I'd bought some time ago.  I also finally got the rear lip painted and fitted.  I then got the exhaust done. It's just a catback for now. Custom made 3" stainless with a turn down. I could have a tip coming out, but it will require cutting the rear lip and possibly the bumper itself. So far I do like and it's made the car a little more zippy.  Close out with some nice pictures of the cars and a sneak peek of what's next.

      This lady loved her FD for 25 years!  https://www.topspeed.com/80-year-old-woman-donates-fd-rx-7-mazda/ My brother in law. He's nice enough to let me drive it whenever. He'll likely not see this, but I'll try: @r-is-for-fun got any pics?

      Just something I found searching for more info on Emotion R, apparently the ECR33 Skyline GTS25t was either originally black, or there were two of them, the black one being the original demo car, then building a white one which was part of the 1997-onwards (to at least 2008!) Cockpit Tatebayashi Tokyo Auto Salon booth demo cars. It appears that Emotion R closed down in 2008 and was declared bankrupt in 2010: http://bank-db.com/hasan/208365. Scan of a magazine with the black R33 from 1996: Wayback machine archived page from May, 2000: https://web.archive.org/web/20000529061027/http://www.emotion-r.co.jp/skyline.html Option magazine with a few photos from the Cockpit Tatebayashi booth at the Auto Salon from various years: 2002: http://www.jdm-option.com/photo/index.php?action=item&category_id=154&image_id=3507 2003: http://www.jdm-option.com/photo/index.php?action=item&category_id=137&image_id=3033 2005: http://www.jdm-option.com/photo/index.php?action=item&category_id=116&image_id=1831 In 2008 Cusco website mentions that the Cockpit Tatebayashi ECR33 was displayed at that year's Tokyo Auto Salon: https://www.cusco.co.jp/event/2008/12/post_735.html As of 2021 it appears that the ECR33 demo car ended up being exported to Florida, USA: https://rmcmiami.com/inventory/1996-nissan-skyline-r33-cockpit-tatebayashi-demo-car-big-te06-turbo-endless-brakes-lsd-450hp/ And finally here's Google streetview of the Emorion R garage in 2023 which is amazingly not only still there, but the showroom is still full of various parts in stock and funishings, etc.: https://maps.app.goo.gl/ttyEAZdZLyzermyT9 Apologies for nerding out a bit. I used to love doing this 20 years ago on SAU and got a bit nostalgic for a moment... 😅
