Recently, more like a few months ago had a set of 18x8's fitted to tein flex's on my s15.
Although the guys weren't very knowledgable about adjusting the suspension height in general, they had one guy who had done so before.
The team were dedicated at getting the right height so that the car handled and looked well.
The worked past their regular 4:30 stop on the friday just to get the job done.

Even though there was extra work involved in the adjustment I was only charged an extra 1/2 hour of labour..

these guys supply can get most major wheel brands in.. speedy's enkei's roh's koya's antera's and a few specailist lines too.
