LS1 Thermostat Mod
I just stumbled across these two articles which talk about shimming the stock thermostat to lower the effective temp. I did a search and couldn't find anyone who had done this to their 'vette. Anyone have any experience with it? Seems like a good way to save ~$60 for a new t-stat.

I did mine after buying a 180 hypertech stat and it failed. I used .100 in shims and the car runs around 178 on the highway on a cool day - whatever that would be :)

I don't mean to hi-jack this thread but, where do you get the shims. I've read about this before. I want to shim to about 180, ~.07 and, I haven't a clue on where to get the shim.
Thanks,

I've e-mailed both owners of the threads and neither sell and shim material. Looks lie we'll have to dig it up ourselves.

I just looked around the junk box and found a small ball bearing that was ~.100. A dremel with a cutoff wheel and a nail (or stainless screw if you are ****) will work also.

I bought the Hypertech and it works, just as advertized. If it doesn't , I would suggest looking for another cause. On my car there was quite an accumilation of leaves blocking the radiator....

Re: LS1 Thermostat Mod (hogurt)
Are we talking about a way to save $60? :banghead:
I am not sure, but I won't "rig" anything on my $50k car.
