it would be cool to have diff engine options for the LX's...and maybe the dev could just make 2 diff engines that the only diff. in the engines is the sounds....or powercurve or if they want u could even have a power diff go for it devs!
well i can see the logic behind the request, as a standard Lotus-7 rep (be it caterham, dax, tiger, quantum, whatever), can be made with pretty much any engine you want, so +1 for the idea.
However, -1 for the practicality, as there are so many options, it would be impossible.
Next you'll be asking for De-Dion rear suspension on them!
