Just wanted to come on here and give a short review on the Rush SR. I searched this forum for any reviews/insights on the car before I ordered it but didn't find any.
I received my Rush SR a few months ago and was able to run a couple track weekends with it at Homestead with NASA. I highly recommend taking it for a test drive if you are interested in buying a race car. I test drove it last year and immediately placed an order for one and proceeded to sell my Ariel Atom SRA. The difference between the SR and Ariel is night and day. The car feels very planted on the track and I feel very comfortable pushing it to it's limits after only one track day. I will post a video here after the Sebring event. Unfortunately my Smarty Cam had a loose cable so the Homestead video I have cuts in and out(I also forgot to enable the overlay).
