B4's or B6's

is there any noticable diffence bettween the two? or is it negligable? also do the B4's make a diffence over standard suspention?

B4 is the model used to replace standard dampers. They're considerably better quality than the Vauxhall fitted ones, marginally tighter and will last more than 20k.

B6 is the "sport" damper, and you'll find they're considerably tighter than the standard ones. Only go with those if you can cope with a choppier ride or you do track days etc. They're good around town and on A- and B-roads, but if you do a lot of motorway driving you may find the B6 a little too bumpy.

Edit: I see they do two types of B6 - one is firmer than the other. I think the B6 I had as part of the B12 kit was the firmer type. If you go here you can see the difference: http://www.bilstein.de/cms_website/e...cts/Catalogue/

Isn't there also the question of lowered suspension and the choice between the two? As I understood it, the B4s were okay on std and SRi (-15mm each end), but if anyone went a lot lower, say more than -40mm over std, then B6s or even B8s were needed.

Might be wrong though, cos I'm looking at switching to 'softer' B6 with Eibach Pro sometime in next few months, from a std ride height (just got to sell the flippin house, move and free up a spot of capital). Having said that, I also fancy doing a few other mods, but it's down to cash with them as well...
