Hey there, back again. Well I have been doing LOTS of research on Superchargers. Downing Atlanta seem to be the only one who manufactured kits for the 318iS, but stopped when they could no longer source the MP62 supercharger from Eaton. Well as it transpires, another company called Magnuson products (http://www.magnusonproducts.com/
) DO stock the MP62 blower .... and an Australian company called Harrop Engineering also stocks a compatible unit, unfortunately neither of them do kits for BMW's of any kind, let alone the 318iS.
SO.... email sent to Jim Downing at Downing Atlanta and I wait to see if they bother responding............... I am a little disenchanted, I have to admit.
With regards the strut brace, I went and had a chat with my local suspension specialist. He gave me a very long winded and technical answer about dynamic forces and other stuff.... but the short version is that the alloy brace I am getting is OK. Phew !!
Still hasn't arrived yet though
