Talked to Ray about these some more. Ray knows what he's talking about - lots of track experience, etc. in his track-only 05 STI (TTA). He also has an 07 WRX that has the BR Series on there along with big brakes, sways, end links, 18" wheels, etc. The coilovers have been on the car for about 2 years with no problems. Several track days per year also. The quality of the parts is really good. The range of adjustability is good. He thinks for a street car that sees some track and autocross days the BR Series are perfect, especially for the money. For a track-only car he would go for the ER Series to get the higher spring rates and independent adjustability on compression/rebound.
These come with a 1-year warranty. After that it is $95 for a replacement.
Have sold a couple sets of BR so far.
