Light weight rims ?

[Birnie]

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?

Reducing unsprung weight is always a good thing.

Lightweight rims *should* make a difference to handling, acceleration but I doubt that many can 'feel' the diffence.

those 17" volk rims are about 8 - 10kg each

say save 5kg each, u are talking about 20kg all up, that's alot!

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.

u seems to be right, i got a magazine here which put them on a weight.

TE37 19x9,5 - 9.42kg

CE28N 18x8 is 8.99kg.

SE37k 17x8.5 - 7.16kg

Gran light 57s 17x7.5 - 8.05kg

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),

We fit light weight flywheels to improve the responce from our engines... It is the same deal with rims, drive shafts and anything else that must be wound up by the engine.

R33vit: what drive shafts do you use/rcommend?

Like in Gran Tourismo, Carbon Fiber ones, but it will cost ya around 8g's.

$8,000 for a c/f draft shaft?

Anyway, I was asking for brands/models rather than a generally "the lighter the better".

I am sure there are a few jap manufacturers that make chromemolly driveshafts that make chromemolly flywheels.

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

I just bought some Enkei F1 rims, very lightweight rims in 17x9.

That's why forged is better than cast

Sorry for the late reply.

I meant as an example. The lightning af all drive train parts would help a engine respond quicker. I would not be able to afford such extravagant modes
