I dont particularly like low grip driving and use RS on virtually everything - although using RS on a Prius for example just isnt right, almost feeling like an X2010 in slow motion you have so much grip compared to power.
I prefer the higher cornering speeds and shorter breaking distances RS tires give, keeps the speed up more. I understand why people like low grip driving, and I agree that it can be fun. Its just that the only times i've really enjoyed it is when im using either the Tank Car or a near-stock FD RX7, the latter of which was only on sports mediums.
Comments like this, however, make me laugh:
Racing Medium and Racing Soft tires should just be removed. None of the cars come stock with these tires (the highest being Racing Hard tires).
RE: an earlier comment that was along the lines of 'you need to use low grip tires or you arent good', thats nonsense.
I was in a room the other night with a bunch of people that I belive often race on low grip tires. It was 450pp Sports Medium, with only abs allowed. The first race around the ring, I got quite badly beaten (not last!), albeit that was partly due to me climatising to the tires and partly as I was using the Tank Car.
The next 7-8 races were very close, I used a stock (barring transmission and supsension etc) '00 RX7 type RS in them all at 448pp, I could run with them and often was faster than them, despite the fact I never use the tires.
Im not claiming im great or anything - I know im not.
