Aluminum is a very soft metal. When it is polished, it looks great, but it's very high-maintenence, so I have eliminated them from my line of products. To replace them are these STAINLESS STEEL units...much harder metal to stand up to the elements. I make them in all 5 "standard" trim radiators which include OEM NA, OEM TT, Koyo, Howe, and Z1 Howe. These are NOT universals. I can also make one for you if you have any other radiator made on ther planet that you can install on your Z32.
The introductory price thru the remainder of the month of September is $200 plus $12 shipping. The regular price for these will be $220. If for whatever reason you can't access my website http://www.megaz.net/ you will soon be able to purchase these at AMZ Performance.
