Will PTG race this in ALMS in 2007?

Thanks for the great pics. Rumors that PTG will run at least one of these in ALMS later in the year...hope they're true!

Cheers

I bet PTG would race it as the E90 M3 won't go into production for awhile.

146Kg or 326lbs. I would bet the one going into the Z4 M R is going to weigh a bit less than that though.

[Kaptain]

Dyson's new AER V-8 (twin-turbo) engines that power both of its new Lolas weigh just 250 pounds.

[Hallen]

It is purpose built for racing and nothing else. The M3 S54 engine is a street engine. You could probably take 30 pounds off with just removing the AC components.

[Kaptain]

The S54 has an iron-block which adds weight when compared to an aluminum block.

BMW's M5 Product Information Guide says that the 5.0 liter V-10 weighs 240 kg/529 lbs.

Hello,
I still can't find anyone at BMW to provide information on the Z4 coupe Motorsport kit. Would anyone have an e-mail address, contact name or phone number at either BMW Motorsport or BMW who can provide additional sales information.
Thanks,
Harold
