Welcome to the club! Yes the forums still going all these years after starting (started back in 2009!), got our regular members who keep it ticking over. We also have quite a few members from the Netherlands here, and infact a lot of members from all over Europe.
Looks like you've been busy with your aerodeck! They are brilliant cars, and just seem to go on forever. The 1.5's are getting quite rare now (can't remember the last time i actually saw one) so good choice.
The change in suspension transforms these cars, check out our members cars for ideas. Simple swaps the the MGZS suspension makes a big difference to the handling (and lowers it a bit too) and is a cheap and easy way to improve them. MeisterR make coilovers specific to the Civic M's (I bought them for my MB6 5 door vti and also my Aerodeck) and are fully adjustable. Again, the difference in handling is amazing, no more understeer!!
Enjoy the club and forum mate!
