Spoke to jkm about ic....they commented that the Ths is very heavy..
Weighs the same as the s3 and the twintercooler together so no real comparison to be made.
I would have a twintercooler if the hose fitment wasn't so bad. Never liked the fact so much cutting about is needed and that if you put one of the undertray screws back in it will go straight into the hose.
THS has been running perfectly on the vRS for over 2 years now. Takes a little longer to fit than the twintercooler though. Usually around an hour longer. Also the most oem fitting if you don't want a cooler sitting right behind the bumper.
Forge are just releasing a new cooler to match the THS along with a larger alloy rad. Not sure if its on their site yet but I'm told its larger than the THS.
