Erm... First thing is to understand the suspension layout and how it works, the Koni adjustables only adjust the damping of the springs, which give the ride height. So it's the spings that you'll need to drop the car 60mm. The Koni's will only 'control' the chassis at it's lower ride height/spring strength.

And spring strength is the key, the stronger the spring, the tougher the ride.... But.... The Koni's will only control rebound.

So... 25mm drop springs with strong re-coil strength and Koni's set to maximum adjustment = fillings in the footwell....

But...40mm drop springs with softer re-coil strength and Koni's set to intermediate adjustment = nice compromise ride.

BUT.... It's a shot in the proverbial dark, as the Koni's are only adjustable off the car.

IMHO 60mm’s too much, Koni’s on rock hard are too much…

Best Chassis set ups are compromises… Including the ARB’s and bushes…

60mm might look good (if you can find the springs), but the spring rate is almost certainly going to be too hard as the Koni’s will need to be equally as strong to ‘control’ the bounce… This will lead to a perfect set up for Castle Combe… But not your local B road or High Street… The car will bump steer, tramline and suffer torque steer… making it, ultimately slower than it is today… Even though it doesn’t feel like it.

Trust me, I’ve been there with Koni’s…
