I've seen THIS on german ebay, I was actually lookin for some coilover (mostly for the look, no racing needs) and I thought the price of these was interesting.
Does anybody ever heard of B+G, or have any experience to share?

B+G is a swedisch investment firm that decided to step into car tuning (and allready stopped since it was too much of a hassle to get a good name....)
These are rebadged Intrax coilovers which normally cost approx. 1080 Euro's.
Think the quality is approx the same as the cheaper Biltstein kit an more for track than road use but definitely not bad and always better than just lowering springs.

so i suppose I won't have much customer support in case of failure - but seriously, do you think they'll be too harsh for road use only?

The dampers can still be ordered at Intrax but no there will be no guarantee.

However I know a car that fitted them and I liked the ride, a bit firmer than standard with H&R springs but you get control over your car in return.
Step in some Audi's or Beamers and you know what really harsh means.....
