As for getting a ECU as your first engine mod... unless you like having to retune your car after every mod you get, eg intake... headers... catback... etc... i would recommend you sit down and do a fair bit of research into what you are going to buy, because some mods can work with the stock ECU where as other need a ECU to operate properly, and decide if your going to:
a) Get the ECU tuned for a stock car, then retune after every engine mod
b) Get the ECU tuned for a stock car, then buy the rest of your mods, get them fitted all at once, and have one retune.
c) Get mods that are compatable with the stock ECU, then get the aftermarket ECU and have them all tuned at once (only thing you would worry about would be headers, most STREET intakes and catbacks will work with stock ECU)

As for suspension... please do ALOT of research in that department also, as some things work and others don't.

But yeah... its time to read as much about moded DC5r's as possible.

Good luck.
Hmm i agree with 45SET he is 100% correct would b a huge hasle to keep retuning ur ecu so just do all the mods you can with out having to touch the ecu then buy a ecu when u want more power, DC5R is all about handling as it is a track car so dont buy cheap suspension get the best u can afford , peace.
