I tried the FXR 'Grip' set around AS3 and managed to do a 1:57.8. I race on AS3 a lot, mainly on AMG and have done 1900+ laps on it so I know the track and the car quite well. My PB using a Conedodgers set is 1:42.19.
Some constructive criticism about the set;
1. It has a 23% restrictor on it.
2. Downforce is set on max (front and rear)
3. Gearing is too long for any circuit. I didn't get into 6th gear and vmax was 134mph opposed to a usual 167mph.
Also one setup for all circuits isn't going to be very fast. South City will require a completely different setup to a fast smooth track like Aston/Kyoto.
It's a nice idea you giving something back to the forum community, but I think some of the sets could probably do with a little more attention.
