    Great springs

    Swift makes great springs. I haven't put these in yet, running different springs now.

    It's a matter of trial and error to get the car balanced.

    The picture is what is in the car now. The helpers are too soft so I bought assist springs as well.

    Swift with springs

    Excellent customer service and product. Highly recommend purchasing from this company. Just had my first autocross with the new springs and they performed excellently. Quite happy.
