What's good about Titan, as mentioned, is that it is customizable and serviceable. I visited them after reading good reviews and feedback from the forum. They took me for a test drive in a customer's car (which I don't think is appropriate... I won't want my car to be test driven the way it was driven if I left it with them...) and when I asked them about lowering ride height, they offered to chop my stock springs which didn't sound too right to my ears. But nonetheless, I have time and again read numerous good reviews from those who have gone to them!
p/s : I visited them about 2 to 3 years back
