I know one of the guys took most of the exhaust off because apparently it was to loud for the mot (although it flew threw many mots with it on when i had it) it did have a remap and it should have a printout in all the history. Im currently trying to find the same koni coilovers for my 180 so will put the link up when i find them (they have adjustable stiffness on the top mounts, front and rear, if the car still has the proper adjuster key for them it should have the part number on that,
The car was a track car before i got it but i couldnt find much info on that
if you have any other questions just ask
