And don't forget to take into account that they are to very different cars. One is a front wheel drive mini replica and the other is a RWD, front engined, turboed bugger to try and drive fast. You can't use the same techniques driving a FWD as you would use in a RWD car. Completly differenct dynamics involved. And that my friend is the the beauty of LFS.
But, a few pointers to get a RWD drive car to handle better. (I come from a mousing perspective so if you wheel then you could disregard some of them more technical aspects)
Firstly, handling. Slow in, fast out. You can't chuck a RWD car around like you can a FWD. The engine is in the front so all the wieght is at the front. The driven wheels need all the help they can get to keep traction so keep it steady. 'Feel' the car and the limit of traction you can't just put the pedal to the metal in a RWD. You need to ease the throttle and ease the car around the corners. You'll soon get it right and you'll appreaciate the driving experiance all the more for it. Prehaps if you mention whether you are a mouser or not I will help you get the best out of your driving if you use a mouse. Obvioulsy a pedal and wheel setup is less critical of throttle input.
Secondly, setup. (Obviously with a mouse you need to take other things into consideration. Again, let us now what control method you are using and we can get more in depth depending on what.) To give yourself a more stable setup is the aim here. As a beginner you want a forgiving, easy to drive set untill you get more confident and able to control RWD. As mentioned have a look at the Inferno sets (There are other's around too. I think Bob does some easy drive sets) but keep away fom the WR sets. They might seem appealing but trust me you will not be able to drive them. They have been tailor made by the WR holders and their styles and skill levels differ greatly from your own. Instead just keep it simple. I would really reccommend that you take some time to learn how to setup your own car. It may feel you don't have the time and that you'd rather be racing but setting up is as much a part of LFS as racing is. You will probable find that the better you get the more you will wan't to set up your own vehicles anyway. That way you can tailor your car to your driving. Also, by learning about how a car handles you can adjust to a RWD car easier because you understand why it handles the way it does. You should learn about wieght transfer, grip levels, dampening, ARB's and all that jazz. Because LFS really will reward you for finding out, LFS really is that good.
But you probable won't want to do that, you just want to be out there racing. So a quick fire checklist for you to look at in your setup. Actually scrap that, I need to know if you mouse or not.
Tell me that and I'll help some more.
