I recently took off my 17" Volk AV3's and temporarily fitted 18" Speedy Cheetahs and noticed a slight power decrease. I'm guessing that's due to the Japanese rims being lighter in weight. Wasn't very much but certainly noticable, so should be the same during a dyno run? I'm replacing those Cheetahs with Gram Lights next month anyway so hopefully I can reclaim that lost (1.5kw? ) power.

id be more worried about how much time u lose on the track. and to answer that question, its impossible to tell you lol.

[Ehgriez]

how fast can you run in CHROME army boots made in china?

a: nobody knows, they fall apart by the first step.

the wheels will add load to your hubs, which might make it marginally lower, but the kW difference should be negligible... however the added weight of the rims and the lower profile tyres will affect your handling much more noticeably.

Also maybe people who run bigger wheels opt for cheaper/less grippier tyres, and therefore on a dyno there's more slip?

[pharoahs33]

So what ur saying is differance wise on the dyno it should be a little differant. It won't be a massive difference like 20 kw! LOL if u got 20"a on the car compared to the stockys 16"s can u lose 15 or even 20 kw atw if say i pull the 170 kw mark on the dyno.

if you have 20's on a skyline the dyno will read fine, only problem is that you will be ghey

[Mr.Massive]

lol - love the last ansa. all depends how much ur shoes weigh - shouldnt b much difference

so will i be ghey if i roll up in a stock r35 with stock 20s?

[Bliksem]

Well they wont be made in china or 3 sizes too big if they're stock

no cause the r35 is not a skyline.... its a nissan GTR

but nice try

You wont loose much power at all but you will find that the engine wont rev out as fast and in turn you will lose accelaration.

LOL!

an r35 gtr comes with 20" wheels stock so it wouldn't be ghey at all. however a 33 or 32 gtst with aftermarket chinese 20"s = ghey + chinese made - coolness = fail at life so jump off a bridge.

^ you guys are so helpful...

[joeyjoejoejuniorshabadoo]

the anti 20" posts are probably the most helpful posts in this thread actually....
