I weighed my rims last time they were off and they were 20.5kgs front and 22.5 rears.

Light weights are around the 5kgs + tyres aren't they?

About 10kgs all up maybe? i dunno.

Anyway, is there much performance gains noticed by this upgrade?

Cause apart from the obvious weight advantage, you'd also get the less weight for the rear wheels to spin up which surely would make a difference to your power cure. Not neccesarily the top kws but a fatter curve cause you must be able to get there quicker.

Is this a correct assumtion and if anyone has done it, did it feal much different?

:headspin:

Tony: I think you probably could tell the difference with a stop watch. The less powerful the car the more the difference should be apparent too.

Maxx: 17" TE37s are closer to 7kg I believe. Regardless, its more than just a standard "20kg" because (as Tony mentioned) its unsprung weight so has a far more detrimental effect on power than sprung weight.

Edit: TE37 specs: http://www.wheelspecs.com/specs/wheelmodels/425

Yeah the extra two inchs (and width) make a difference ;)

As for the others: Gram lights are cast (except for the 57Fs AFAIK) so I would avoid them (too soft). CE28N and SE37k are too fussy a design for the Skyline IMHO: would look good on some Euros though (thinking and Alfa or a Maserati),

I have some Enkei 2 piece rims on my car, 17x9 front and back and each came in on the scales at 12.5kg (including tyre).

They have always been on the car, so not sure if it makes any handling differences, but if you hit a pothole the do dent a hell of alot easier :)

    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
