LFS is a simulator yes? IMHO road cars shouldnt have the amount of adjustments they do now i mean when would you have adjustable gear and diff ratios on an econobox for instance? If that same econobox was to be raced then thats a different thing as it would have roll bars to start with and run on semi slicks at least.
Even if it was club spec racing the cars still wouldnt have the amount of adjustability they do now, sure its alot of fun making sets but most sets are made to take advantage of LFS's flaws rather than be repeatable in real world situations.
Make the race cars racier and leave the shopping trolleys to tyre pressures and minor stuff , maybe to please everyone the current cars could be like RL and come in stock, club and full race versions.
Thats my two cents which is actually worth one cent due to the economic crisis atm..
