The cost was about $2000.00 and it came powder coated white with a bracket for a detatchable swim platter. I really checked them out and their work is flawless. The owner, Colon has been in the business forever and runs a clean shop. I went with them mainly because you really pay for the Armstrong name, my quote was $3100.00 for the same application. I will let you all know if the wives tale of 10% better speed and economy holds true but I'm not holding my breath for a 48mph top end with only 115's. [img]images/icons/rolleyes.gif[/img]
