i'm contemplating black matte forged wheels (maybe hre p40 series) for my agate gray c2s and i'm a newbie to aftermarket wheels. is there a huge difference between hre wheels vs any other monobloc forged wheel on the market (besides the large markup)?
thanks

Forged wheels are generally stronger and lighter than cast wheels. That being said, not all forged wheels are made the same. HRE, Forgeline, Volk and BBS are probably the best wheel brands out there. Their products are raced regularly, and you are paying for premium quality. IMHO they're worth the price. When buying forged wheels, take a look at the tonnage of the forge press they use, weight of the wheel, and the warranty offered.

I've got a set of 19" P43S for my 991 C2S, and they are fantastic.

If what you say is correct, porsche must feel comfortable putting cast wheels on many variants of premier sports cars. If I don't track the car is there any major advantage of forged over cast wheels that justifies the price differential. The ROI seems minimal in DD setting.
As this is my first foray into porsche, are there many complaints from 911 owners in regards to the oem cast wheels?

If you're not going to track the car, either wheel will be fine. Just watch the weight of the wheel, and make sure to get something that is TUV or JWL certified.

I'm using my iPhone right now, but I'll post more about forging when I get to my desktop.

Simply put, these certifications provide a reassurance in the form of proof that, for example: albeit cast, the FF01 is a strong wheel - capable of withstanding a large amount of force, abuse, heat, etc., while simultaneously displaying an attractive design.

We know you sought the input of fellow members, but we hope you don't mind a brief explanation from us. If you have any questions regarding HRE wheels, please let us know.

Would you expand on the aftermarket wheel purchase- for example other posts in this forum note there is no issue moving to 305's on a c2s without changing the wheel( 20x11). Also, what about tpms, center caps, ? Offset( what does that mean?), lug nut pattern,etc.. If I'm going to drop 5-7 k on wheels, tires, etc., I would love more insight direct from the manufacturer.
Thanks

I think HRE and Forgeline are either 5000 or 6000.

BBS makes a very good cast wheel as does ADVAN.

Thats pretty much the range. Fully forged are around the 5.5k-10k range.
