Hi and welcome!

I have a very similar build...only diffs may be bicolor red leather interior and stock exhaust...for now.

I would consider the Alcantara...I've had it in many of my cars, including Lambos but my Huracan and Rover SVR are now full leather. I think the H seats in Alcantara would be more comfortable and next time around I will probably go back to them, they grip you better too. The Rover seats feel much nicer and do not mind the full leather here.

Unless it's changed, you have to take the lift and Magneto together, I think both are mandatory along with the LDS. To be honest I have not driven a non-LDS H, but I couldn't imagine it being any better @ low speed or on the track without, the LDS is great IMHO and a huge selling point.

Save your $$$ and don't spend it on the Mimas, buy some ADV1's instead, you're in the ballpark of 7k, stay with OEM sizing so you can reuse your factory tires and sensors, if not add another ~2k

Depending how "aggressive" you like your exhaust, saving $$$ again and going aftermarket is a better bet.

If you don't opt for the full Style Package I'd at least opt to incorporate some of the design elements. The front gloss black splitter and exhaust tips in black look great against Rosso Mars. It also adds gloss black to the grills, front bumper grill trim, and bonnet side vents. I have this package on my car...check this thread New member, photographer from Chicago with exotics in the garage!, tons of picts of my car, Mars with ADV1's. Look for picts of other Rosso Mars with a red front splitter; these do not have the Style Package for comparison.
