I would not recommend these guys for a couple reasons. I went there for a quote, and they would not put any numbers down on paper.Also, I've been racing now for 20 years plus, and all they were doing was spouting offthe latest gimmick words and trinkets to throw on my car. They don't have the track experience they claim...a lot of exaggerations is how I saw it. Very typical..."add a couplegizmo's, do a vid and throw pics on the net, and hope the fools come rolling in to wastetheir money". If you want good track advice, you need to find guys who were at the track last week,not at the track last year. These guys are just hobby accessory installers...IMO.
