Wondering what is recommended for hoses on a track day C6? Lots of info here about radiators and coolant/water/water wetter etc. but couldn't find any on which hoses to use. Car is 2006 C6 LS2 MN6 with 68K miles. Factory radiator cracked so wanted to do the whole system while I'm at it. Leaning towards a DeWitts with integral oil coolers.

Thanks,
Steve

I am still running the stock hoses from 2003 on my C5Z06 racecar. I haven't seen the need to change them for something more expensive.

Stock. Unlike the old days, OEM hoses are pretty darn stout. If money is burning a hole in your pocket, take a look at Samco.

Stock, but on a track car I think I would start carrying spares after 5 years.

I had the same thought you did and replaced all my hoses with silicone from a Corvette Forum vendor when I installed the new radiator. That crap sprung a leak in less than a year and I went back to OEM. Also noticed that the vendor no longer sells those.

Insufficient sealing capacity at the joints?

Sounds like factory hoses with regular replacement is the way to go. Has anyone done a materials stress test for temp? From what I can find, temp would be the main concern as chemical resistance to oils, fuel, and ozone are good.

Pin hole leak in the middle of the hose -- you can see the streams! Got these from LG Motorsports and they leaked after 13 months and 7500 miles. "More durable" the ad said.

My LG's have been on for 3 years for me and counting. They came with the car when I bought it and were probably 1-2 years old already. Ripped out the radiator twice in the last year, lots of R&R around the hoses, no issues. I think you had a fluke. Another vote for LG Silicone hoses here.
