BCRacing Coilovers Standard Springs Rates?

Anyone know the spring rates that come with the BR Series ZB-01-DS kit?

Back around 2011 I purchased a used set of BC Racing Coilovers (BR series) from someone on the KappaPerformance forum. However, they had custom springs rates of 6kg front and 8kg rear because they were into auto crossing.

I've since decided to buy some new softer springs rates from BC, but their BR series spec page does not state what the standard spring rates are on ZB-01-DS coilover kit.

I contacted BC and was told the springs are: 62-220-7kg @ $50.00. So I'll be ordering four of them this weekend.

Beware that the front and rear stock springs on the Solstice and Sky have different spring rates.

The people at BC are frequently wrong on this topic.

Buyer beware!
