Hi londoner,
Yes, I have done it. I have been the lastweekend under the car for replacing the cooler and uninstall the air conditioning.
Result: Cool Air, but a great action ... insured hands and fingers, an aching back and so on. And as always, you get the feeling that some bolts and washers are coming just from the Titanic...
Our stock cooler has a 1.5 cm air-gap to the condensor of the aircon. The new high-performance allali-radiator is 1cm thicker than the originals (52mm). So regarding your 32mmstock-radiator there must be enough space for him even with the aircon to assemble. But there must be one of you Lotus Turbos who must proof this exactly as your nose is different.
I have asked the manufactury whether they could also build a 42mm variant too for those of you, who want the aircon stay in place, so you get a greater gap between it. But I couldn´t recommend to let the aircon in place. First I have hesitated also to destroy the completeness of the car. But if you look at the pictures, you will see, that the condensor covers the radiator in such a complete way, that any kind of clean-up operations failed. So my cooler died an agonizing heatdeath

And the condensor would have been followed in 1 or at least 2 years cause his back wasn´t able to be cleaned too. Furtherwise the dirt of the condensor was sprayed on the radiator too. So it is not only a Lotus-law to add lightness

it is necessary with view to the maintnance.
Additionally, the cooler is now of course more efficient, his layout serves more coolness like the plus of material does it twice, it is also nice to keep it clean and -ultimately- it is a wonderful piece and design which could everybody see, who must bowdown in front of the erotic lines of our cars
So i am very happy about the cool breeze in the engine bay: MORE cooling POWER, a weight saving of more than 1,5kg, a better weight distribution, less understeering, …
For the next examples I would have let shortened the manufactury simply the pins at the top a bit, as it has not much space to the construction in my case But this is forced due to handmade carvariations not due the radiator.
