Thanks lads, went with the DW 65C for the moment as it seems simple enough and I can upgrade down the track when I look at getting into the higher HP's.

Soksta, I had a look through your driveway thread and seen that you had the STI wing attached to your Rex... I gave Neil a ring at Unique Auto Refinishings and just waiting on a call back now, if you read this before he rings back, roughly how much did the part, fitting and spray of the wing set you back? Looks damn fine btw.

Once again, much appreciated with all the effort in replies. Invaluable lessons being learnt.
