Block Airflow to Oil Cooler?

What would be the best say to temporarily block off airflow to the oil cooler for street driving that I could remove before tracking it?

I've heard that Elises with dual oil coolers sometimes have trouble getting oil to temp with normal street driving. I'll preface this by saying I don't have an oil temp sensor and apparently there is no sensor I can read with OBD2, so I'm not exactly sure if my oil is coming up to temp or not. I'd rather be on the safe-ish side while driving on the street and block of airflow to an oil cooler.

I removed the wheel liner and looked at the front radiators. It doesn't seem like I can easily shove a piece of sheet metal between the air inlet and the radiator. I could attach the sheet metal to the back of the radiator, but I'm not sure if water would get stuck in the radiator or between the radiator and the plate. I guess I could leave a small gap for drainage.

I'm just worried that I'll **** it up somehow haha

Every high performance car I've owned has had an oil cooler, either oil to air or oil to water. There's no reason to believe the Lotus is any different from the other cars. I'd say the safest thing to do is leave it alone.

There is a oil thermostat on the engine which bypasses the coolers until the oil is up to temp so there is no need to block them.

If you want simple, just put tape over the venting slots on the wheel liners. Peel it off when you go to the track. This will reduce air flow through the coolers when the tape is in place.
