You Sir have DM.I will DM you.
Let’s just say there are already 5 GT350R owners with sets on order. Just awaiting the sample wheel to be completed before I post pics publicly. I have a teaser though.

And that is the issue with me. I'm not wanting to build a cars and coffee showpiece that has to have the best CNC forged wheels available that are track worthy. The car came with probably the best wheels that money can buy. I'll use them at the track. I want a set of reasonably priced wheels that fit the part and don't chew up my calipers.To me the key is comparable weight to CF or you are going to feel the difference in car behavior. The P51 set I got for street on my GT350 is fine for what it is, they are very light and look ok. Caliper clearance is not great (is ok) but you get what you pay for. Once I get the R I will make a decision to keep them or upgrade to something that checks that last box (caliper clearance). I am not sure since the price difference to the next level of wheels is almost not worth it unless I want to track them extensively which I will not.
I totally get it. I had similar reqs. I chose what I did because they fit the budget, they are light (same as the signature ones in the 21lbs range) and look fine. The only compromise is the caliper clearance (I believe it is around 3.5mm or so).And that is the issue with me.

I cant see how LMR wheels are of a lesser quality than the 6GR wheels. My only bitch with the 6GR (aside from customer service) is the caliper clearance. If LMR has that aspect of it corrected, it sounds like a no brainer to me.
My budget is in the 2 grand (plus) area. I cant justify spending the forged price for a simple street wheel.
Don't forget, they also have been known to crack. The issue with a spun forged wheel being so light, is that they do not have enough material to support the loads of the carI totally get it.

To me the best solution might be to get a used set of fully forged ones (LMR ones are too heavy IMO) - that is the only thing that fits my budget and all other parameters.
They are definitely not as strong as fully forged ones and I would definitely not use them the same way. Yet I do not think they are a bad option if you understand what you get. And case in point I have been (re)searching failures for these and was not able to find much which tells me hey are not half badDon't forget, they also have been known to crack.

Well, I hope this comes off as data sharing and nothing more. The only reason I bring this up is our Signature wheel was being compared to the offering from P51 in regard to weight. I am not an engineer, but this is what I’ve learned thus far.They are definitely not as strong as fully forged ones and I would definitely not use them the same way.

I am not sure I said anything differently than what you said (BTW, I never even attempted to compare them or say they are similar other than weight).. Except maybe the failures you mention about - I would love to see some pics (you can email me those if you do not want to post them up) - I see that as data gathering as well so people (including myself) can make better decisions going forward.Well, I hope this comes off as data sharing and nothing more.

A spun or rotary forged/cast wheel simply does not have the same grain structure or material density as a fully forged aluminum wheel. The process in which it is produced and the metals used are not as strong. A 21lb wheel of that spun/rotary construction type is going to have inherent areas of weakness due to the lack of material. The wheel needs to be heavier in order to be strong. It is the same reason the OEM cast wheel on the GT350 weighs 33lbs. It had too have so much more material in order to handle the loads it would see from the Shelby. Contrarily, you can have thinner spokes on a forged aluminum wheel because the grain structure is stronger/stiffer and does not need more material.
On the same token, if had a 18lb fully forged aluminum wheel and compared it to the 18lb carbon fiber wheel it likely would not be as strong or stiff as the carbon fiber. You just can’t produce a strong/stiff enough forged aluminum wheel with that little material. The properties of the metal won’t allow it the way carbon fiber will. At least not without some other expensive process to increase density/hardness etc.
With that being said I have knowledge of at least 5 separate wheel failures on that wheel design through my travels. There are likely more. I won’t post pictures of them, although I have a couple.
Not looking to bash that wheel, but it’s important to give context to why a wheel that light, of that construction type, when compared to a fully forged wheel is not necessarily a good thing.
I encourage everyone to go and do their own research and be knowledgeable about what you get. Don’t just take it from me. Like you said, as long as you know what you are buying up front.
