Sorry I don't know the answer to your question, though I've never heard anyone suggest there was a major change to the suspension on LCI cars.
Several things to think about to improve ride quality though:
- Don't go above 18" wheel diameter
- Replace the runflat tyres with non-runflat
- Consider a good quality upgrade to the suspension e.g. Koni FSDs or (if you can afford it) Ohlins Road & Track.
Just my five penn'oth.
