Has anyone used these? I did a search and found very little.
wow, i can't believe a 'search' did not reveal much.
i have recommended them many times here, and like them very much. i had them on my old SW20 Toyota MR2, then my 2L TS 156, then on my 3.2L GT.
i like the option to 'adjust' them. i find the 'softest' setting lacks rebound control (for my liking), so around 3/4 of a turn suits me best. this is with Eibach Pro Kit springs (which were on the 156 and also on the GT).
i have Bilstein B6 on my 155, which i chose to try - something different. they are non-adjustable, but not too bad. a little too firm on the compression, and a little too soft on rebound for me (with Eibach Pro Kit springs); still very good though.
the B8 is essentially the same as the B6, but with shorter pistons and designed for cars lowered greater than about 35mm. so they are no better, just suitable for a different application.
personally, for dampers, i will stick with KONI Sport in the future. only thing potentially better, is a set of coilovers like the KWv2, but i think they would be overkill for a TS 156.
