I was not referring to the cost, but the forged tonnage. The higher the number, the stronger and lighter the wheel generally is. ah I see. Well the OP now knows the price too then lol.

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

As Speedsterr mentioned, the TPMS sensors and caps can be transferred over or ordered along with your wheels - we can cut your wheels to allow the stock components of your OEM wheels to remain intact.

As for the offset, put simply, the offset basically indicates how deep or shallow a wheel will fit inside your wheel well - this also determines the amount of conical (or concave, depending on the design) depth a wheel will exhibit. For example 20x12 wheel with an offset of ET25 will have a greater profile depth than a wheel sharing the same specs but with an offset of ET50. Keep in mind, a wheel with a 20x12 ET25 spec will sit out further towards the fender lip, while a wheel with an ET50 spec will sit further in bore, towards the interior fender lining, closer to the body.

The lug bolt pattern, in this case for Porsche: 5x130, pinpoints where on the wheel forging the lug bolt holes will be bored during the beginning stages of creating a wheel. 5 is the number of lugs required to securely bolt the wheel to the wheel hub/axle, while 130 is the diameter (in millimeters) of the bolt "circle", where the lugs will sit.

Hope this helps!
