Storm Motorsport also run a Oil cooler in the same place aswell.

If you have not checked your oil temperatures why are you contemplating fitting an oil cooler? It is added expense, weight and complication you may not need.
Combined oil temp and pressre guage costs £60 ish. Oil temp only about £40.
You can fit easily yoursef.
FYI oil manufacturers generally claim their fully synthetic oils are good to 140 deg C. Personally I don't want to see more than 125 C.

I would never, ever, ever, want to run oil at 140ºC in an engine on track. Despite what oil manufacturers say it's "good" for, a subaru engine WILL kill itself with oil that hot on track. We run our TA car at a max of 120ºC and you can see the difference in oil pressure compared to 100ºC when studying the datalogs. Hotter oil also leads to increased oil lost into the breathers, more pronounced oil surge and generally lower reliability.
An oil cooler works very well in the TMIC position, on our 2007 TA car we ran a 25 row cooler behind the front left quarter of the bumper, venting into the wheel well, this position is about the worst. For knockhill TA we put a slightly smaller 19 row cooler in the TMIC position, and it worked much better overall.
Heatsoak is nonsense for an oil cooler, don't worry about it unless you want to develop a lot of power at idle, and are concerned about the oil temps while doing so.
The most important bit is as Harvey says, get a temperature gauge!
