sorry, but all these wt are splitting hairs.
if you really want to reduce such wt, then yes, this is one very expensive way to go about it. but it is wt reduction for sure.
if you are in it for the looks, the CL "look" wheels are pretty good and far cheaper. BBS motorsport E88 with CL look cap comes to mind, very lwt as well
if you think CL are easier to change the wheels, you are WAY wrong. the CL on these GT3's are not the cup car stuff. i would actually pay to have five bolts rather than CL.

 

i'm with you here MOOTY

 

Weight is one thing but 20-25k to do this is nuts IMHO....just buy a 10GT3

 

If you can source your own wheels/tires, the actual center-lock conversion kit is only $2600.00 for the 997TT. Not too bad, I suppose.

 

We have done the Cup car centerlock conversion for road cars.
Feel free to drop me a line.


We also offer a very lightweight road and track worthy 5 bolt wheel - the GMG WC-GT wheel 18x9 and 18x12.

 

Fabryce,
Since you guys have done the conversions, I think it would be very helpful if you could confirm the exact unsprung weight savings by making the switch.
Five pounds per corner savings just for the CL hubs seems like a lot. But if correct, that might just make it worth the investment.

 

To be 100% honest I don't know if there are any weight savings. Center locks are used in racing for the ease and ability to quickly change the wheel during a pit stop.

 

Some people installed titanium bolts for the mk1 wheels..
i guess this will shave the 5 lbs per corner ?

 

i was gonna do this a few months ago. i was told 4k to do the conversion without rims. 1k a wheel

 

Guys,

If you look in the GMG WC-GT wheel release thread (there are few so you might have to search) AMT chimed in about the weight difference between CL and 5 Lug. Bottom line, AMT says the 5 lug design is lighter due to extra material required to reinforce the CL design. In the end the REAL advantage of CL is not weight.

You are correct. We are able to make almost any 5-lug wheel lighter than its similar Centerlock cousin. This is true regardless of homologation (TUV or SAE). With all the fastening torque confined to a single area, the resulting mass adds a little more weight, but usually not more than 250 grams.
But the Centerlocks sure look cool! Only you can decide if it is worth the dough for the conversion.
Me? I wouldn't do it.

PS: We don't use the AMT name anymore. The company name since 7/09 is Advanced Structural Alloys, LLC. Forged Alloys USA is our aftermarket division.

 

I couldn't imagine a bigger waste of money. If you want to go faster, spend $10k on driving lessons. THEN, spend some money on suspension upgrades.

I don't care what Porsche says in their marketing material. They are designed for looks...i.e., mimicking what real race cars use.

thanks suncoast on the centlock price. about 1300 less than i was quoted 4 months ago

 

Can't say they didn't also do it for the weight reduction. The same reason the GT2 RS has a sticker on the hood with the Porsche crest, versus the metal badge. Every little bit helps!
