Oh and not too mention that the TM02's are at least 25% less expensive than the majority of the forged lightweight Monoblocks on the market.
Enkei has also proven within their own R&D that the RPF1 is too light of a wheel and will not produce as fast a lap time as the heavier TM02. A lot of material is sacrificed in the thickness of the inner rim barrel. When this becomes too thin it will sacrifice rigidity under cornering forces, even hard acceleration and braking. If a reputed and raced wheel is heavier then there's probably a good reason for it. Please don't be blinded by wheel weight too much.

Im going to ask you for some support on that statement. Start a separate thread if you want, but Im interested to see some evidence of this RnD. Maybe you can email the AME rep for more info.
Bump for my favorite wheels.

It's an extremely valid topic and one that was published in an Option Magazine article back in 2008 I believe. I managed to find a digital copy of the article. I'm surprised I could not find a post for it here.
A quick synopsis is below:
Regular High Rigidity Enkei GTC-01 18×10 +22: 23.76 lbs.
Specially Lightened Version Enkei GTC-01 18×10 +22: 19.8 lbs.
The weight of the lightened version was reduced by 3.96 lbs. Both used Advan A048 (265/35-18 M-Compound). Testing was performed at Ebisu East Circuit using MCR’s Z33 driven by Kobayashi and under the same specs (ie., tire pressure, # of laps, etc.)
Regular High Rigidity GTC-01
Best Lap: 1 min. 4.646 seconds
Top Speed: 147.16 km/h @ 17.83 seconds
Specially Lightened GTC-01
Best Lap: 1 min. 5.045 seconds
Top Speed: 141.46 km/h @ 17.74 seconds
A very rough and quick recap: The surface temperature of the tires for the less rigid, specially lightened GTC-01 were higher overall with extensive wear on the outer portion while not enough contact/usage on the inner portion. The high rigidity regular version GTC-01 showed even usage throughout the inner and outer parts of the tire. Also, the low rigidity, lightweight version wheels gave/bent when taking aggressive high speed turns even affecting the height of the car which even led to scraping and alignment problems. Furthermore, the lighter version accelerated much quicker, but ultimately did not lead to faster times. In summary, Kobayashi expressed that a balanced wheel with both rigidity and lightweight characteristics is important, but he never imagined that the effects of rigidity played such a large role.

Keep in mind this is just for one lap. Imagine an endurance series/race.
This will help explain why Enkei hasn't produced a wheel that's as light or lighter than the RPF1. Post RPF1 all the wheel weights with regards to MAT process have increased in weight to improve stiffness.
What I did not expect was the wheel to outperform the RE30 which is technically a more superior manufacturing process.
FYI, we sell all the brands mentioned above so it makes no difference but knowledge is power. Oh and don't shoot the messenger.

Again, not trying to rabble rouse here, just trying to clarify on your earlier statement which basically said that RPF1s will flex if pushed. The lightened wheels in this test have absolutely no correlation to production Enkei wheels and furthermore they laud the MAT and other Enkei manufacturing processes, which are used to construct multiple Enkei wheels, including the RPF1. Again, duh...this is essentially an Enkei advertisement.
Im sure wheels made too light will flex and alter the desired contact patch under certain loads to the detriment of the tire's performance. Just don't know if throwing the RPF1 under the bus as a scapegoat is the way to do it, especially when you're trying to sell Enkei wheels.
And yes, I used to run RPF1s
Bump for these rare wheels, you don't see these floating around very often.

Well the GTC01 is a stronger wheel than the RPF1 from what I understand. As a result you can use deductive reasoning. The RPF1 is over 10 years old now. Bang for buck you can't beat the RPF1 but just saying lighter isn't always better. Lighter doesn't always mean faster.

To the top. There's been a ridiculous amount of interest. Let's see some more sales.
I'm gonna offer a $20.00 store credit on top of your purchase once you provide us I-trader feedback. Let's get tradin'.
