I think the ride is comparable to my AST 4100 setup with 500/650 and it definitely woke the handling up on the car. I was a little disappointed with the standard spring rates, but at these rates I am REALLY satisfied. To me, it feels like this where it should have came from a performance perspective. Those looking for stock like ride, the 400/450 setup was very good. I would just not run camber plates with those spring rates and stick to the stock top mounts.
Good info. I am actually bumping my rates up to 450/550 at the 7" length.

A recent pretty straight and positive review of the B12: http://oppositelock.kinja.com/e46-m3...kit-1797361567

I need to pull the trigger. I'm not wild about the way my cab is riding...

Mr. Wolfe
Stock suspension lack much, if any, comfort as far as springs and shocks are concerned.

I have had the B12 for a few months and put 3,000 miles on it. They are way more comfortable than the stock SACHS setup.

I moved from the stock SACHS setup / stock 19's / worn out Potenzas to B12's / APEX ARC-8's / Michelin PSS in one shot. So I cannot pinpoint whether its the tires, light wheels or the B12 spring / shock setup that improved the handling the most...but I'm very happy with how my car handles now.

Here are some pictures...

You and I should keep in touch. I'm right by you in RPV and I also roc ka VW as a daily! Know of any other LSB cars in the South Bay? I saw another cab a couple years ago getting tires at Coscto, so I only count three!

Yes we should! I sent you a PM. I'm in West Torrance - you are more than welcome to take a ride in my LSB to see if the B12 is for you!

With my current setup it handles a lot better than my heavily modified (suspension wise) R32 (H&R RSS coilovers, reinforced subframe, swaybars, camber plates, solid bushings, tubular control arms, etc.) - but the R32 is running on Hankook V12's so not exactly a fair comparison.

I do believe there is a LSB owner on 19 CSL wheels in Redondo Beach. So that would make 4 of us! I last saw it parked on the street with a car cover. I think the guy was trying to sell it on Craigslist a while back but didn't sell.

But my neighbor has a PY E46 M3 and there is someone a few blocks down in my neighborhood with a Steel Gray E46 M3 as well. They both are stock. Both enthusiasts but I don't think they are on the forums.
