According to Bill Koenig, the Dymag importer for several years, the new alloy center Dymag weights are as follows:

19x8.5= 7.8 kg 19x11.5=9.35kg

This info as of Fall 2009

 

crazy that the BBS's are lighter than the Dymags

 

Maybe too light = not strong enough and that's why BBS sez the FI is not intended for racing. You can go too far in trying to reduce weight.

 

I saw that warning and you might be right, but I think the issue depends on what criteria BBS uses to determine that the BBS Fi is "not intended for racing." Is it possible they use such stringent criteria that none of these consumer wheels passes the criteria anyway? It's very possible IMHO, considering this is BBS Motorsports Division we are dealing with. Maybe when they said racing, they meant all out professional racing?

It would be interesting to see the criteria they use to arrive at that conclusion!

 

Interesting thread guys. Those F1's do look sizzling hot with the black and polished combo but hell exxy at 2k per rim. I'd also question the durability for street use being so light. Jeez wouldnt you just hate hitting a pothole with those babies.....arrrg!! Makes the P40's a bargain...they too look super hot with the black and polished....great pics .

 

IMHO BBS' concerns are legitimate. On the racetrack, conditions can be quite severe. Often what is seen are high cornering speeds, combined with high cornering loads, combined with rough surfaces (kerbs, pavement, etc.). This can create tough conditions for wheels. These conditions are rarely seen on the street. (Dymag discovered this harsh reality as well).

The BBS F1 product is their competitive response to a strong trend in the market towards lightweight forged wheels. They are well aware of the benefits of low unsprung weight and were losing business to a long list of competitors.
I am always impressed by the amazing "Godlike" reverence paid to BBS. They have an wonderful reputation. But they are human and do not walk on water. $8000 per set is a lot of dough.

 

Hi Mike, very much agreed with the trend towards lightweight monoblock. I hope/suspect HRE, Champion, etc., are all monitoring. And yes 8000 is getting up there. I wonder if that 2000 is for the front wheel, or both? Isn't rear usually more expensive than front?

Ok I am guilty as charged of the BBS reverence :-). It's hard for me not to be so since I keep seeing them on race cars! I've read it's not comped either, no? Thanks again for making this thread extremely interesting and informative for me.

 

Surprisingly, both the front and rear 19" BBS FI's are the same price based on information from BBS USA and Vivid Racing.

 

I just posted the pictures fro my car with the BBS FI

 

Thanks for the info. BTW, you have great taste -- nice mods in your car!

Hn, thanks for the pics. Congrats. Looking at your pic, I could see where the weight saving come from: thin thin spoke and almost no center disc!

Thanks for the info. So I *might* have been right with my theory. It's possible gen 2 Dymag is (ever so slightly) heavier than gen 1 Dymag because gen. 2's center is mag-alum versus gen. 1's magnesium.
Mainly for "academic" interest really, as wheel is of course no longer available.

 

Champion/PES GP7 s are among the lightest rims for 997tt.
19 lbs front and 21 lbs rear.

 

Can you send me a PM please with fittments for 996tt
Tks

 

Can you post images of the charcoal please

 

I just posted a simple photo of the Tech1-110 in Matte Black vs. Matte Charcoal.
Also a pic of the Tech1-207 in gloss Charcoal.

 

Very nice! Is this your car?

I believe the weights of the PES GP7 are 19 front , 22 rear (8.6 kg front, 10 kg rear) https://www.6speedonline.com/forums/...ed-wheels.html , very light and approaching the super-light group. The cost was very attractive too (I believe 4500 or so). Wheel is no longer available AFAIK however.
"eclou" (who else) was the first to have this wheel. Back when all I thought about wheel was "look," not weight.
