what I have seen is the grip seams to be increased WAY to much. I worried I will go through all of this work installing RSRBR only to find it turns it into a joke like SEGA rally.
Can SOMEONE please give me a bit of info on this.
I concur with Damien's comments. Using RSRBR2010 certainly doesn't turn it into an arcade style game, it is still very similar to the default RBR in many ways. Of course, the physics varies quite a bit depending on which cars you drive (and RSRBR2010 adds a huge number of cars). I have tried many of the arcade style Rally games, and RBR remains waaaaay ahead in the driving realism.
As Damien has already said, the only way for individuals to test it and decide is to install it and try for yourself. The good news is that the default RBR is still available for your use as a comparison, RSRBR doesn't replace the original content, it just adds a whole new amount of content (cars, tracks, track surface options, weather options) and of course, most importantly, the option to race on-line (you can also use RSRBR2010 off-line if you wish).
The installation process may look complicated at first, but if you follow the basic instructions, it's actually quite straight forward. Everything is simple auto installers. Install the base RSRBR2010, install the update 03, then install the cars (either complete car set, or individual or class car packs depending on your desire).
