the front is where you feel the hardness of the co's... and 2's in the front will be very hard. I will probably change the fronts up to 8/12 and rears 7/12. I've heard from other sonic s1 users that this is a good setting. Freeway dips are great - no more bottom outs as I did with the H&R's!!! and I am slowly getting used to my new handling. The car is definitely more confident in the twisties and I am really enjoying the new characteristics the vehicle has now.
