First and second radiator brands in 3 row are aprox. $600. The third and fourth brands in 3 row are aprox. $300. Advantages? Disadvantages? Warranty? Experience?

I can share my experience with DeWitts a few years ago and I’m totally happy with it. Drop in installation with no issues. It keeps my car right below 200 degrees in Japan summer traffic and I couldn’t ask for more. It comes with a seal to the radiator to the shroud and a thin spacer, but everything fit perfectly. I will paint the plastic spacer black the next time I’m in there. I’m very please with the quality and customer service. Best wishes in your quest.

Dewitts here in AZ desert runner with Dewitts SPAL fans. 5 years no issues to date

Dewitt double row since 2015. No complaint!

Bought a single row DeWitt for my first ZR-1. It was drop in and go. Even the single row has 50% more capacity than stock.

My current ZR-1 has a Ron Davis radiator probably 20 years old. Perfect!

Perhaps before upgrading, there's this anecdote:

After my bumper and radiator got smooshed (WANNAGOFAST incident), Pete had a stock radiator he'd swapped out of a customer's car for a 3-row after market radiator.

While the stock radiator was out, I soaked the core in Simple Green for a few hours, and then back flushed the crud out using a pressure washer (a car wash pressure washer would work to, I recon). That was circa 2014 and my temps stay right in the window established with Marc's fan control settings ~205y ish.

It has never over heated except for one incident where RPM was in the cavitation region too much (doing some spirited twisties in Rocky Mt Nat'l Park:o)

At any rate, when I back flushed that core, I musta flushed out a quart of sand and bug guts before the core was finally clean. I couldn't help but wonder if all that debris was the reason someone was having Pete install a new after market radiator in the first place??

Keep an eye on those 30 year old plastic end tanks....

Ron Davis is for you highly modified guys and I get that. But what about Champion and Frostbite? Are they welded? Epoxied? Made in China? Say they fit but don’t? What is the caveat? It is a three wait from Summit to get a Dewitt but will ship a Frostbite tomorrow.
