In search of affordable and strong wheel options...
I own both forged and flow-formed wheels for my '19 Z06/7. It is quite early to tell how these wheels will fare since I could not yet stretch the car at the track or even on the road due to poor/winter weather, but I am starting to think that we don't necessarily have to get forged wheels to ensure the wheels are not bent at harsh conditions.
The problem It seems to be the inner wheel of the (especially rear) wheels are the most vulnerable part of the wheels that bent. Of all the issues reported, I've actually never heard of spokes being an issue. It makes sense that the inner lips of a massive 20"x12" will be highly leveraged, as they are very far away from their support point (the spokes). Solutions suggested
Thoughts? https://lh3.googleusercontent.com/AJ...b_BLrPoM=w1280 Forgestar CF5V 19x10 ET30 front (23.26 lbs), 20x12 ET59 rear (27.32 lbs). https://lh3.googleusercontent.com/q7...eVrviZd0=w1280 BC Forged RZ39 wheels 18x11 ET38 front, 18x12.5 ET59 rear; knurled bead option. |
Thanks for your thoughtful post. Forgestar's are what I'm considering myself. I would love a set of Forgelines, but I just can't stomach spending that kind of money on rims when I may not even have my car in 2 years. Then I'm taking a huge loss to sell them.

I've been running a set of Forgestar F14's for about 6 months now and I'm happy,18x11 and 18x12 on a '17 GS. They are hugely popular with the Mustang crowd and for under $1500 I think it's the way to go if your, like me, just want some inexpensive 18" wheels. Actually I got wheels, R888R mounted, and TPMS for $3k shipped to my door. Fully forged are definitely lighter and I think look better due to the less material used in the hub and spoke area but I'm not competing, just HPDE.

Great post. Flow-formed has an excellent reputation (TSW, forgestar, Flow One etc) with very modest cost. I've heard no horror stories from them.
True forged wheels *may* be stronger though I don't know if that is so. They are lighter, by 5# per wheel or so. I doubt that makes much difference except at the very highest level of competition. The non-custom flow-formed wheels are so cheap they are almost disposable. Will be interested to see how BC forged vs Forgestar plays out under similar usage. |
I have personaly had CCW forged wheel crack a spoke, so it can happen with the best & strongest available.
Seems to me that if your using Hoosier DOT or slicks. I would stick with the strongest you can get. Broken wheels at speed are worse than nasty!!! Also as to the weight issue it is far more than one would think. I can feel the difference in ride and handling as soon a driving away from the change (garage or pits) |
As the rim (barrel) is strengthened it can function as a lever transferring the max stress to a weaker point, one that might not otherwise be exposed to such stresses and bend/break there... just saying, there is more to stress analysis and looking at and strengthening any given location. :yesnod:

My thoughts exactly on the topic. I've literally been batting it around for a month now and is the only thing stopping me from picking up your old Z51 BC forged sets
|
regarding the part number change, I believe forum member jenfioreally indicated that GM had a recent change in vendors for the wheels which would have precipitated the change in part number. Whether or not this had any change in the wheel material or design, your guess is as good as mine. |

Part numbers are 23317165 front and 23317166 rear. |

Strong, light, cheap... pick two. The other is inversely proportional... |

Another high wheel would be HRE's nice wheels but good gravy are they high, I have a set of MRR M107's in 1LE fitment on my 5th Gen Camaro and I've done a track day with them and they held up well is also my daily driver. |
Keep your eyes open for good used forged wheels. I just bought like new HRE’s for less than new flow formed wheels. |

I hear ya on this. That's why whenever a customer purchases a set from me I make sure that in the future when they come back for another set I take that first set in on trade - or at least help them sell it on consignment free of cost. If you go with a brand like HRE that is known for their legendary build quality you get a much higher return on the wheels as opposed to some of the Chinese manufactured companies mentioned here. |
Please ask jenfioreally, same issue and we see this weekly on the C7s. We carry all the Premium Forged wheels and all utilize the best APP Forgings which are more costly than alot of others.
I personally run Forgeline because of cost/quality factors but any of our Forged lineup is fantastic. If we can help CALL/TEXT 440-915-6166 Here is my C7R w Forgeline VX1 https://cimg5.ibsrv.net/gimg/www.cor...ba2cce7b2.jpeg |
Shortly after buying my new 17 Z06 I purchased a set of Signature forged wheels in sizes 10.5x19 and 12.5x20.
They weigh 21 and 23 lbs. respectively. These are my everyday wheels with about 7000 miles logged so far. Zero issues. Fit and finish are fantastic. If I could do it all over again, I would have opted for an 18 in. set up to gain side wall cushion. My drag pack set up are Forgestar F14's in sizes 5x18 and 12x18 which don't have many miles on them, but also perform as expected. I do drive a 40 mile round trip with them mounted from the house. My biggest take away is trying to drive around known potholes and other road hazards in my area. So far so good. I can also vouch for the TSW flow formed wheels. I have a set of their 18 in. Intelagos sized 8x18 for my winter wheels on my Golf R. They also racked up some 15K miles on my VW Sportwagen with no issues. |
