LCR is not as good on the twisties as the CTR, end of!!! And grip isn't the
problem either.. Having owned a CTR for 3 years and 100,000k and the LCR for just under 3 years and 80,000k I thik I can give a good unbiased opinion.. The LCR has a lot more grip than the CTR i've found (well with Conti sports on it anyway) and mine's mapped!!!! The CTR is a lot more chuckable though, the better handler and just more fun in general..
As for speed. Same skilled driver in both, similar to about 90, then the CTR will start to edge away, tried and tested many many times with my cars and my mates.. But obviously people meeting others on road will have different outcomes as more than likely driving skill..
Both great cars though, leave it at that I say..
