No sure if anyone knows yet or not but i found a website for silicone hoses. Its not for kits but you can buy by the foot. I got all the hoses together that i would need and it only came to $58.68 (compared to $170.00 on others) thats for 40 ft of 3.5mm 15ft of 4mm 16ft of 6mm and 4ft of 8mm. Since rx7store is not selling them no more. I thought i would try and post some helpful info. Website is http://www.siliconehose.com/

 

Yep! Thats where I got mine last year also. Fast delivery and appears to be good quality.
I posted this on someone elses thread and they said it was to good to be true and must be low quality but I have compared it to Hose technigues and looks and measures the same!

 

Boostcontroller.com is also good
