If you can get some Lotus centre caps then those wheels might
look quite good.
However they may not
work quite as well as the originals.
The lower profile sidewalls will make for a stiffer ride and may upset the car's already brilliant handling. My Elan had already had its suspension "breathed on" when I got it, and while the lower ride height looked great, I've scraped the nose a few times on speedbumps, garage ramps and even in multi-storey car parks.
When we did our IOM trip back in about 2007, my Elan performed superbly on the track-day that we did there, but on bumpy roads it pogoed about so much that it felt nervous and quite frankly unsafe, which caused me to slow down. So in a nutshell, it was as fast if not faster than any other Elan on track (on the day), but amongst the slowest of them in the "real world"!
You need to research your tyre sizes to ensure that you don't muck up your speedo or grind away your wheelarch liners.
Bear in mind you'll also have to declare the modification to your insurers. This may not cost you anything for the first mod or two, but they can start ramping up the premiums after that.
I don't want to put a damp squib on your idea - I'm all for performance upgrades if they return the investment and are done right. What "grinds my gears" is when upgrades that have cost you a lot of money actually end up making you go slower!
Lotus ride and handling engineers were and are some of the best in the business, and the Elan had about the biggest development budget of any Lotus ever. If wheels have been introduced to the market that do the job even better than those on which our cars were originally designed to run, then that's great. Question is, do you want to spoil your car, or spoil your car?!?
