I recently purchased Tein Basis Advance from 949. Despite a small delay due to waiting on springs I requested Emilio shipped the coilovers to me saturday even though it cost him a bit more. As always 949 went the extra mile to make a customer happy.
Coming from xidas (had to sell due to my budget for this year so for the price of my used xidas I got coilovers, c3ms, and 225 rs3's)
Coming from 700/450 xida the ride quality is surprisingly very nice. They are no xidas, but still very tolerable given the rates.
As for the damping I would have to say the same thing. While no xida the coilovers do a pretty good job despite a very bumpy airport with very bad tarmac.
Overall on if someone is on a budget I highly recommend these. My car had to run in DP the day of the event, but had I put in all 30 lbs of my interior I would have won STR by over a second.
So needless to say interior is going back in and im dropping back down to STR.
Here is a video of my best run.
