Love this product!  I have been using RS683 since spring of 2010 in two of my cars and have noticed a firmer pedal feel in both. At the track, both my V70R Volvo and Porsche 911 Carrera have had no fluid boil issues either on track or during cool down in the pits. I cannot say the same for [...]

RS683, Brake harder deeper, longer… I’ve been using RS683 in my Porsche GT3 for a couple of months now. This stuff is really great! Keep up the good work!
