Forgestar F14 vs Forged rims
 

Hey guys, currently i have stock sport package rims on my 370z. I am looking at the forgestar f14 because i really like how they look, but i was told that i will lose tremendous horsepower having these rims because they are not forged. Can anybody give any insight on this? Thanks

Tremendous, no. Some, yes.

Would you worry about the loss or not really? I do occasionally track a little

I'd worry about tracking on cast stars, not the weight

Is cast star a certain type of rim?

Play on words, because Forgestars are cast

Lol my bad. Now I get it. I'm guessing I could just use oem for the track and forge star on the street. Appreciate the help Andrew

That you could do, and many actually do. :tiphat:

Your wheels are forged from factory, please don't downgrade.

Cast wheels are not always a downgrade but in general forged wheels are both lighter and stronger.

I just wish they made this style forged.

They could have done it but the price would be astronomically not feasible for volume sale.

The rays oem sport wheels if bought from rays its cost is somewhere around 4k.
But due to being flooded in the market it only sell 1k used.

That's true

Yea I realized they sell a lot, but mainly I guess people just DD these wheels. The other wheels that I'm looking at are advant garde's and they are 4x the price....

Yea, but Rays/Volk rims are not a top quality product. When it comes to Rims they are mid level grade.

You can buy a high level wheel for 4k a set which will be better in every single way then a Volk wheel.

There are a ton of differences in "Forged" wheels so I will try to break them down for you as simplistically as I can.

The first type of wheel are cheap forged wheels. These are generally your knock off rims. They are cold forged meaning they are formed at room temp with a press that just forms the billet into wheel shape. They then are mated with another billet of various sizes and put into a form flowing machine to produce the barrel.

The second type (rays/volks) are hot forged with a press into a certain shape. The hot forging allows for far better strength and more detailed forging that allows for a lighter wheel. This is then mated with a billet of various sizes and cold spun (form flowed) to make the barrel of the wheel.

The third type you will find on high end race wheels are hot press forged throughout. These wheel forgings are extremely strong and they also include the barrel. The barrel is machined first on these wheels and the barrel size is determined before machining begins. So you have to have the correct forged blank so sizing can be limited as a result. The barrel is turned and then the face of the wheel is cut to the specified design by a CNC machine. This process allows for very fine details compared to both the Cold and Hot press forging as you can cut the blank however you want. The main drawback is compared to a Forged Spoke shape you do cut the grain structure. The offset also has to be cut off the pad to get the desired fitment for the wheel. There are limitations to this pad as well so again fitment can become an issue as you have to have an appropriate forged blank to start with. This leaves you with an entirely forged wheel both center and barrel and they are extremely strong. They are far less likely to bend then a Rays style wheel due to this additional strength.

These wheel are fully forged and are the strongest aluminum wheels you can buy on the market and the kind of wheels you should be buying if your racing.

Which rim would you recommend? Ssr?

Forgeline's :) no doubt about it. I might be biased though as I am a employee of the company. However, if your looking for a set of top quality wheels I can certainly get you the best deal possible on a set of Forgelines. There is no doubt though that Forgeline does make the very top quality of aluminum racing wheels.

P.S. I should note that I do not have much to do with the wheel manufacturing at the company and I only work extremely part time as I am usually busy with Racing Obligations/My Business (shop owner)

I'm gonna check out some of their wheels. I'll pm you if I see one that pops at me. I appreciate it.

Just to throw in my .02$

The OEM 19" Rays wheels are awesome. Good quality and I think they look great.

For the track i got 4 18x10 Forgestars F&R. They hold up great on the track and are lighter than stock 19" (and with tires are lighter than the stock setup). I can also rotate front and rear.


If I had the money I'd go for CCWs, but I'm cheap.

Have you had any problems with them on the track? How is quality?

I have had 3 track events on them, I clean them and inspect for any cracks after each day and have noticed none. They seem to be holding up fine. My one gripe is that I was using wipe on paint stripper about 20 feet from my car one day and I guess some of the fumes made their way to one of the wheels and it got a few spots of corrosion. The finish on them isn't that great, but for the price I think they're hard to beat. Steering does feel lighter with them on (although this could be more of the tires than the wheels).

On the other hand, the Z1 1-piece rotors...

I appreciate your help. Were yours factory color? http://tapatalk.imageshack.com/v2/14...25bc7b389d.jpg

That's one the cleanest z I have seen in awhile. I'm trying to get to this level on the rims. They look nice and possibly NISMO conversion.

Mine were the 'factory' silver. I didn't want them some other color or powdercoated so that it was easier to see cracks if any developed.

I wonder if I can get bronze factory. What tire set up are you running?

You can order them in just about any color, that said powdercoating does hide cracks.

I'm debating on 19" with 255 front and 305 backs. I don't want 18" to be small


Sent from my iPhone using Tapatalk

For tracking or looks? If I wanted a 19" wheel that looked good personally I'd just stick with the OEM ones. Also note that to get a good thread engagement on the lugs you should read the "all about lug nuts" sticky in wheel/tire forum.

19" for looks and oem for track day. I want to do 255 and 305 on oem as well


Sent from my iPhone using Tapatalk

Don't mean to talk you out of Forgestar, but why not pick up an extra set of the OEM 19s for track days

19" for looks and oem for track day. I want to do 255 and 305 on oem as well. I'm gonna check out the thread on that. I appreciate the help. I'm gonna be doing car shows and feel like I'm kinda cheaping out semi from what I have been told if I get these.

The only thing is I don't know how bad track days can ruin rims also because they cost about 1,200$ lol and forges far is 1,600$


Sent from my iPhone using Tapatalk

They shouldn't ruin rims unless they are Rotas or something that are going to crack. For track days I'd use that $400 difference towards brakes or disposables.

How do sport package brakes hold up? I thought that's what everyone was using? They work so far lol. I'm not sure what you mean by disposables?


Sent from my iPhone using Tapatalk

In my experience OEM Akebonos do well if you have good fluid and pads. I don't drive 10/10 though. They will likely discolor the OEM finish on them though (mine have gone from gunmetal to more of a moss-grey).

By disposables I meant pads, trans fluid, diff fluid, brake fluid, oil, coolant.

Should I start replacing them? I'm pushing 4,100 miles. Fluid wise


Sent from my iPhone using Tapatalk

If you are going to track i replace tranny and diff fluid after each event, brake fluid after each event or within 90 days before an event (whichever comes first) and oil every 3750. I dd the car with a few events a year

Gotcha, I'm about to do my second oil change, got one done at 1,200 and now switching to redline at 4k. I baby this thing. Any problems with the car after tracking? I'm scared to do more than one a year bc I will eventually dd it and don't want to break down.

I haven't had any problems related to tracking and my car just hit 50,000mi. However tracking a car does wear it out faster than hard-parking it. But you got a sports car to drive it, not park it!

There are some good threads in the track/autox/drift/drag section about upkeep of a track car and common wear items.

I really appreciate all the advice and by hard-parking do you mean street abuse? You're right about the sports car part. Didn't buy a Prius lol
