It does suck that these companies are going belly up.
But the prices they are asking (im not just talking about ARC here either) are just stupid...DO these companies not know that there are now heaps of import parts being produced by American and Australian Companies that offer the same level of quality but at 1/3 the price.
Asking 2000 dollars for a 15 year old design intercooler kit is a bit silly. The prices should drop as time goes by and after they have paid off their R&D costs, as per the American market.
Think the LS1 V8 for example, 12-14 years ago stroker kits were US$15k+ now the very same kit is US$6k or less, and the company has developed cheaper kits as the market became available for them to do so.
The Japanese tuning companies have not, and IMO we the buyer have had enough of paying through the nose for a HKS/GReddy/ARC/Tomei stamp on the side, especially when the product dates back to the mid 90's, and we have local product here we can buy for much less.
Another E.G is JUN con rods, they are Produced by Arrow in the UK, and cost around AUD$2K for a set of 6, now you can buy the exact same product minus the JUN packaging for around AUD$1200 from Arrow.
Maybe the Japanese car owners do not research their stuff and simply point at a workshop car and say "I want the exact same as that" or they believe the parts list has to have all the big names on the side. I'm not sure, I did see above that they were moving towards the Cheaper Chinese Sourced parts like HPI etc.
Anyway I may be way off, but there is my tree fiddy
