Holy Old Thread Revival!
Anyhoo...
I just bought a set of BC BR coilovers and chucked them in my Gen 3 SW20 today.
Fairly straightforward fitting process apart from the brake line brackets being a bit thicker than standard. This resulted in some 'persuasion' to get the lines to fit in the brackets properly.
I also had some issue with the camber bolts on the front, but that was probably more me than anything else.
I'm going to get a wheel alignment and the castor and camber tuned for best cornering performance, but from what I can tell thus far, they're pretty good.
I've gone for the previously mentioned 16 clicks rear and 10 clicks front from the softest setting, but I really need to do a bit more 'testing'.
Overall; happy with the price, they look good, they're simple to adjust, and they were pretty much a straightforward fit. Would recommend. :)
