Thanks all
I will probably end up with the manual if the thing has an outside chance of temperture issue in the heat especially here in SFL. This would also be a secondary track car with the M3 trading the duty. The M3 has just had a complete cooling system upgrade and never gets hot on track.
Here is the one I kinda like. Not sure on the Megan coilover for this car. I would try out the Dinan stuff but I think there is better out there for the N54.
