That's the spirit, never give up. Some 16" wheels fit over the DE brakes, that are very light and inexpensive, but would that be a good reason to do it? lol

 

Yup… sometimes we pick a tire/wheel setup for the wrong reasons.

I notice that 350z drivers who track use 18” or 17” wheels, but 19” wheels are a rare choice.

And… it seems the better a car performs on the track, the shorter the wheel diameter, but the wider the wheel and it’ corresponding tires

- Formula 1 racers use 13” wheels
- Stock car racers use 15” wheels

 

While I fully understand and agree with the concept of lighter wheel = better performance, I highly doubt that was OP's intention when he bought a cheap, heavy wheel to replace a good looking, quality OEM wheel.

So that discussion hardly seems relevant in this instance.

 

The stats for the XXR 526 are actually quite good:

XXR 526 17x19” wheel: 22.5 lbs

XXR 526 17x10” wheel: 23lbs

 

They look good man. Just lower it about 2.5 inches to fit the car. It will look a lot better.

 

well maybe not that low. 1 pic looks like you got a lift, and the 1 of your rear wheel looks like its lower. It could just be uneven ground.

 

That's a lot of sugar coating but we should keep it real. Sometimes members buy what they can afford but at the same time it's not always in the right direction. Modding for the sake of being different isn't always an improvement. As long as the OP is happy that's all that matters even if we don't all agree with his purchase.

 

Well the Enkei RPF1 in comparable size weighs about 16.75lbs and 16.9lbs so I don't know if I'd say these XXR wheels are quite good.

I don't know many other wheel specs but I can't see those weights for a 17inch wheel being really great. I'd think they are average/heavy at best.

Obviously you get what you pay for (to an extent) but I would say these wheels are heavy. If OP had of gotten them in 18inch they would be even heavier. But let's be clear, in 18inch variety, I think they look quite good on the 350Z. I just think the weight argument is silly considering the given situation.

 

Yes. Was looking for a setup I could easily rotate. The spacer will make the rear look more full as opposed to the tire.

 

Tragedy into a worse tragedy. Should've stuck with oems.

 

The only reason f1 has kept the dinky wheel ratio is because of cost. New wheels means more research and the f1 teams would have to redo their whole suspension setup. Larger wheels means less play in the sidewalls which means better steering.

 

With the amount of money teams like Ferrari generates I'm sure money isn't an issue to do the research. And what about NASCAR, WRC, FIA GT1, FIA GT2 and Super GT?

 

XXR 526 17x9” wheel: 22.5 lbs

XXR 526 17x10” wheel: 23lbs
--------------------------------
Enkei 17x9” wheel: 16.4 lbs

Enkei 17x10” wheel: 17.2 lbs
---------------------------------

The difference is 6 lbs. That difference is huge for the track and insignificant for the street. I know my choice when running on the track.

So… There you have it.

 

Wrong… wrong… wrong… I don’t know what else to say. Cost is NOT an issue here.

The companies spend so much money, but not on stuff like wheels and tires that the manufacturers compete to provide to teams.

 

Still waiting for the OP to post up the excellence.

 

op's Z kinda looks like it has one of those billy goat beards or a weird looking chin strap. I think that is where the excellence comes in?

 

The don't run 13" as far as I know. I'm not sure what you trying to get at.

A simple tire size change means whole suspension geometry change, hours upon hours of real track testing, and the tire manufacturer constructing a new tire. That plus the new engine regulations would be a tight squeeze on the budget. Just trying to have an constructive argument.

Anyhow back to OP, rotational mass and unsprung weight sounds nice but if you are not tracking the car, you are going in the wrong direction with tire size. I wouldn't track with reps though.

 

Didn't know we had so many F1 industry experts here. How did you guys get that far off topic? lol

 

Formula One wheel sizes have been fixed at 13 inches (330mm) for two decades

 

Besides F1, some cars in FIA GT use smaller diameter wheels than their stock counterparts and so do rally racing. That's what I'm getting at. But op's not tracking is car so who cares. Whatever tickles his pickle.
