Hi, I was looking into some titanium retainers and I came across KMS Engineering's Ti-Retainers on ebay and saw they were only $110 + shipping. I was going to order the crower ones, but I like the price of these. Only downfall is that I've honestly never heard of them. The parts look like they're well designed and they do other things also: Springs, valve guides, etc... And I've heard of some people on this board of having engines built by them, but never heard of any results. So if anyone has any opinions about their quality/workmanship, lemme know. Thanks.
