[SBillinson]

I put a $110 single-core radiator with plastic tanks in my modified car because it was the lightest one I could find. I have put about 50 passes on the car running between 145-147 MPH and the radiator has held up fine. I've slammed the front end several times from violent wheelstands too.

I have a fitted aluminum fan shroud which may provide some rigidity but it attaches between the tanks. It's definitely not holding the radiator together.
