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.

Re: SSR forging technique (the general URL was posted earlier, this is the info specifically about the construction):

http://www.tirerack.com/wheels/ssr/ssr_info.jsp

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

LOL sorry - must have missunderstod... If you got the money then go the jap rims :)

I did :):)

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.

wow, diggin up a 3 year old thread, nice :)

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.

    • Initially I thought having a pair of Recaro seats would be a big bonus, it turns out these do get a little uncomfortable on long journeys (my fault, not the seat). I had a look through the GSM Performance website at reclining seats and booked an appointment to visit their show room. I got the Recaro Sportster CS for the R34 from here, was very happy with the service received so of course a re-visit was in order. Unfortunately the two Corbeau seats I had chosen aren't on display but they had 4 other options available. Two seats dug into my back, one dug into my legs and the other was perfect. I also found out that Recaro seats use a larger bolt pattern so some adaption was required. Luckily GSM offer some universal adaptors that should solve this problem. I searched the interwebs for price comparisons and Corbeau themselves were the cheapest at £300 cheaper (for the pair). I asked GSM if they could price match, unfortunately they couldn't. I later received an email saying Corbeau would honour them the same discount, but the purchase was already made. I did however order the brackets from GSM, both arrived on the same day. I started with the passenger side seat, knowing this was going to be a little trial and error. There are 3 mounting holes at the front and 2 at the rear on these JURAN Racing seat rails.  With the adaptor brackets mounted, the allen cap bolts started to push into the seat, NOT GOOD!  The rear mounting holes lined up but there were issues at the front. The holes were 1/2 hole out, so the brackets got a tickle with the drill to modify the holes. The supplied bolts weren't going to be long enough and a spacer was needed to stop the adaptor bars from bending. A local fasteners company supplied be with some nylon spacers and longer bolts (M8x30, although these will be replaced with 35mm long shortly) A before and after I pre-drilled the front bracket before making a start on the driver's seat to save some time. And in no time at all that was in the car too. The all black seats have transformed the interior and these are MUCH more comfortable. The only downside with the new Corbeau seats is I sit a little higher, but I'll happily accept that over discomfort. The Youtube video can be found here: https://www.youtube.com/watch?v=wPyttKPktXA
    • All 3 I guess. The car came with the JASI Aero 4 door Type R Full Kit unpainted so this was one thing at the top of my list to complete then I noticed there were body panels parts for this kit so i picked them up along with some black mesh to fill in the front bumper and front side air vents. car is at a paint and body shop atm completing this work. Next I will be addressing the internal bells and whistles, great summer project I can do with the kids.  full interior removal - ,boys car sound deadening - pads and spray ,boys stereo, sound, lighting - Big 3, GTT or bigger alternator ,kids head lining - dye black add star lighting mod ,daughter. That's it for the next 5-6 months. I have some motor maintenance  work i have to plan out. oil filter relocation, gaskets, mounts. beyond that, mind is starting to turn over if i can use a DET intake plenum, block off turbo ports & pipe in a air intake.      
    • roller coaster of a ride. Alarm system was removed & main harness was repaired where possible. still no fix just random successful starts. moved on to the replacing the ignition switch and relay. well all this troubleshooting & repair has been going on, the car is at a paint and body shop being pushed around. Ive been going down there on odd days after work to get it sorted.     
    • 5th November if you want to come out for a spin wakfield
