TC klein? how do I contact them

["Jeff Lloyd" <jslz3@hotmail.com>]

TC Klein and his race shop are famous in the bmw community,
I am aware he has done a lot of development with the Z3 platform
and I would like to contact him or one of his developers, (not a usless 
sales person) but someone that can give me answers on solving handling 
deficencys I am currently experencing with my stock class setup. I also 
would like to purchase the required parts.

Thanks
Jeff Lloyd
